The objectives of this study were to identify socioeconomic, market and agroecological determinants of farmers' maintenance of rice diversity at the household level and derive implications for policies in designing on-farm conservation programs. We assess spatial rice diversity at farm level using household survey data. A household decision making model is conceptualised using microeconomic theory to assess and identify factors influencing on-farm rice diversity. The model is then tested econometrically by using various factors affecting farmers' variety choice and diversity decisions. The findings show that household-specific socioeconomic, agroecological and market factors are important in determining on-farm rice diversity. The significant variables in explaining richness and evenness of rice diversity include distance to the nearest market, subsistence ratio, modern variety sold, land types and adult labour working in agriculture.

This chapter discusses the challenges to agroecosystem management, and how adopting a diversifi ed approach will enable farmers to farm longer and more sustainably in an environment of greater uncertainty, in the face of climate change.","owner":{"id":32955890,"first_name":"Devra","middle_initials":null,"last_name":"Jarvis","page_name":"DevraJarvis","domain_name":"wsu","created_at":"2015-07-10T02:44:02.203-07:00","display_name":"Devra Jarvis","url":"https://wsu.academia.edu/DevraJarvis"},"attachments":[{"id":44850482,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/44850482/thumbnails/1.jpg","file_name":"Challenges_to_agroecosystem_management20160418-524-1edmxng.pdf","download_url":"https://www.academia.edu/attachments/44850482/download_file?st=MTczNDAyNzM2MSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Challenges_to_agroecosystem_management.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/44850482/Challenges_to_agroecosystem_management20160418-524-1edmxng-libre.pdf?1460979466=\u0026response-content-disposition=attachment%3B+filename%3DChallenges_to_agroecosystem_management.pdf\u0026Expires=1734030961\u0026Signature=NEd14JO1a4EobW1~5HOpRTi7u-FTMPoUh8qX3rUvyUP4pFdzLefDNKt7i-sBtXdEwxe2oAzDaPhil-XYCau4SKz-xzNSaqdjm3CajlIusZmyMEEPngwafY~A7ALxwLiGJDgaS~Nl1BSYNwzaSzuXH8DIykxfORpU0Tmp~I7UK4usWZEbMaF71H1d8pPs~~55fjAZGaO9Qzn54TGKIPU9NFKC5i6rdrPKMYZ2qPLPkyRl~vVTLavbhsgSi5~PDkoupXWjXlbDeTL3XQkOgLYMZjJrOl0ZSIMEqcIbtDt5ICOUzt~PeSwJtqSTzMoAPJ6kq4HybhVHGwghOyjeqGNxCQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="13874927"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" rel="nofollow" href="https://www.academia.edu/13874927/All_Maize_Is_Not_Equal_Maize_Variety_Choices_and_Mayan_Foodways_in_Rural_Yucatan_Mexico"><img alt="Research paper thumbnail of All Maize Is Not Equal: Maize Variety Choices and Mayan Foodways in Rural Yucatan, Mexico" class="work-thumbnail" src="https://a.academia-assets.com/images/blank-paper.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" rel="nofollow" href="https://www.academia.edu/13874927/All_Maize_Is_Not_Equal_Maize_Variety_Choices_and_Mayan_Foodways_in_Rural_Yucatan_Mexico">All Maize Is Not Equal: Maize Variety Choices and Mayan Foodways in Rural Yucatan, Mexico</a></div><div class="wp-workCard_item"><span>Pre-Columbian Foodways</span><span>, 2009</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">...

While many cases of deliberate introgression of desirable traits into crop cultivars as part of breeding programmes are known, the extent and significance of natural or farmer-assisted introgression is uncertain. A range of techniques have been used to document natural hybridization and introgression of agricultural crops and their wild relatives in many crops including maize, wheat, barley, oats, pearl millet, foxtail millet, quinoa, hops, hemp, potato, cocona, casava, common bean, cowpea, pigeon pea, carrots, squash, tomato, radish, letuce, chilli, beets, sunflower, cabbage, and rasberries. However, the majority of these studies are based on morphological characters, and few have investigated the frequency with which such new types are produced and retained in natural and agroecosystems for farmer selection. Even more limited is information on the role of farmers in recognizing and selecting new genetic variation from the natural introgression of crops with their wild relatives, and the impact, once selected, of these new genetic combinations on the crop diversity. Molecular evaluation of natural introgression linked to investigations of farmer recognition and use of introgressed types provide ways of evaluating whether farmer selection for introgressed types is a significant process in increasing the genetic diversity of crop plants.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="89a678b776f4106cd594fd18a2328942" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":44850488,"asset_id":13874924,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/44850488/download_file?st=MTczNDAyNzM2MSw4LjIyMi4yMDguMTQ2&s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="13874924"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="13874924"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 13874924; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=13874924]").text(description); $(".js-view-count[data-work-id=13874924]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 13874924; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='13874924']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 13874924, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "89a678b776f4106cd594fd18a2328942" } } $('.js-work-strip[data-work-id=13874924]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":13874924,"title":"Wild relatives and crop cultivars: detecting natural introgression and farmer selection of new genetic combinations in agroecosystems","translated_title":"","metadata":{"grobid_abstract":"Whether new combinations of genes that result from hybridization and introgression between wild and cultivated taxa are maintained, with the resultant development of populations with new characteristics, depends on natural selection, and in the case of crops, on human selection.

On farm conservation is an important component of the global strategy to conserve crop genetic resources, though the structure of costs and benefits from on farm conservation differ from those associated with ex situ conservation in gene banks.

Jumli Marshi was the most common traditional rice variety, accounting for 85% of samples collected. The genetic diversity of these landraces was assessed by agro-morphological variability and microsatellite marker polymorphism. Forty-two qualitative and quantitative traits and 39 microsatellite (simple sequence repeats, SSR) markers were assessed among accessions with 10 different names. The accessions showed low morphological diversity with an average Shannon Weaver diversity index of 0.23. Only 16 morphological traits showed significant variation among the accessions. Discriminant function analysis showed that only 36% of accessions could be clustered according to name by morphological traits. Only one SSR locus was polymorphic, distinguishing only one accession. The names used by farmers to describe the phenotypic characteristics of panicle and grains were inconsistent indicators of genetic identity.

A baseline survey in Jumla, a high-altitude site (2200-3000 m), identified rice landraces with different names that differed in phenotype and were adapted to the extreme high-altitude environment. Jumli Marshi was the most common traditional rice variety, accounting for 85% of samples collected. The genetic diversity of these landraces was assessed by agro-morphological variability and microsatellite marker polymorphism. Forty-two qualitative and quantitative traits and 39 microsatellite (simple sequence repeats, SSR) markers were assessed among accessions with 10 different names. The accessions showed low morphological diversity with an average Shannon Weaver diversity index of 0.23. Only 16 morphological traits showed significant variation among the accessions. Discriminant function analysis showed that only 36% of accessions could be clustered according to name by morphological traits. Only one SSR locus was polymorphic, distinguishing only one accession. The names used by farmers to describe the phenotypic characteristics of panicle and grains were inconsistent indicators of genetic identity. We conclude that the Jumla landrace population has a narrow genetic base. The diversity detected was sufficiently low for it to be possible that there was a single origin for all of the Jumla landraces. #","owner":{"id":32955890,"first_name":"Devra","middle_initials":null,"last_name":"Jarvis","page_name":"DevraJarvis","domain_name":"wsu","created_at":"2015-07-10T02:44:02.203-07:00","display_name":"Devra Jarvis","url":"https://wsu.academia.edu/DevraJarvis"},"attachments":[{"id":44850491,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/44850491/thumbnails/1.jpg","file_name":"j.fcr.2005.04.014.pdf20160418-2109-95sq2y","download_url":"https://www.academia.edu/attachments/44850491/download_file?st=MTczNDAyNzM2Miw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Rice_landrace_diversity_in_Nepal_Variabi.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/44850491/j.fcr.2005.04.014-libre.pdf20160418-2109-95sq2y?1460979465=\u0026response-content-disposition=attachment%3B+filename%3DRice_landrace_diversity_in_Nepal_Variabi.pdf\u0026Expires=1734030962\u0026Signature=a3-E0qZjwXMkfM~S5SP9wBayl039bqt5ffzWjRJgsXZX7vZdJrND59NJ87ql8zKAO04MIG-kZ4CbiytcxjSkny6wAtzsH7dRCVU2-gIKclXE4vM65I-JKO4UHuKs8WGSbcqtHUE-VjfyFDmo724jWJC4BZ3DLCM3k79kFrhb7WJSOIbdstnzLBr1srjJECinU9fRuxjIcEs2ekZK7yU-zlIaIjgexDhoD-VimueTYlBkYJEvNzGi8wP6D-kvkAXs-WU~KiA5Y1MpNc9U5fBWVoUJpvyfKZ5jm8XlSK5VIEF2MCYbx27a0qo8DI9zQnPw~y8OucVsm9cUPixq2k1aUQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":156,"name":"Genetics","url":"https://www.academia.edu/Documents/in/Genetics"},{"id":3855,"name":"Polymorphism","url":"https://www.academia.edu/Documents/in/Polymorphism"},{"id":43028,"name":"Genetic Diversity","url":"https://www.academia.edu/Documents/in/Genetic_Diversity"},{"id":87479,"name":"Field Crops","url":"https://www.academia.edu/Documents/in/Field_Crops"},{"id":217324,"name":"Soil sciences","url":"https://www.academia.edu/Documents/in/Soil_sciences"},{"id":227672,"name":"Discriminant function analysis","url":"https://www.academia.edu/Documents/in/Discriminant_function_analysis"},{"id":547589,"name":"Quantitative Trait Loci","url":"https://www.academia.edu/Documents/in/Quantitative_Trait_Loci"},{"id":871402,"name":"High Altitude","url":"https://www.academia.edu/Documents/in/High_Altitude"},{"id":876158,"name":"Diversity index","url":"https://www.academia.edu/Documents/in/Diversity_index"},{"id":2002434,"name":"Simple Sequence Repeat","url":"https://www.academia.edu/Documents/in/Simple_Sequence_Repeat"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="13874917"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/13874917/Who_Maintains_Crop_Genetic_Diversity_and_How_Implications_for_On_farm_Conservation_and_Utilization"><img alt="Research paper thumbnail of Who Maintains Crop Genetic Diversity and How?: Implications for On-farm Conservation and Utilization" class="work-thumbnail" src="https://attachments.academia-assets.com/44850492/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/13874917/Who_Maintains_Crop_Genetic_Diversity_and_How_Implications_for_On_farm_Conservation_and_Utilization">Who Maintains Crop Genetic Diversity and How?: Implications for On-farm Conservation and Utilization</a></div><div class="wp-workCard_item wp-workCard--coauthors"><span>by </span><span><a class="" data-click-track="profile-work-strip-authors" href="https://wsu.academia.edu/DevraJarvis">Devra Jarvis</a>, <a class="" data-click-track="profile-work-strip-authors" href="https://independent.academia.edu/RRana2">R.

This uniform resistance is met by the continuing evolution of new races of pests and pathogens that are able to overcome resistance genes introduced by modern breeding, creating the phenomenon of boom and bust cycles.

A collaborative programme with national partners in Vietnam, Mexico, Peru, Burkina Faso, Morocco and Hungary, and Bioversity International (formerly the International Plant Genetic Resources Institute (IPGRI) has designed tools to assist scientists and decision-makers to understand how scientific and institutional information about in situ conservation of agricultural biodiversity on-farm can be integrated and inform policy choices. This paper shares information about the critical components of the policy development process and how the process might enable a participatory, bottom-up approach for supporting the conservation and use of agricultural biodiversity on-farm.","owner":{"id":32955890,"first_name":"Devra","middle_initials":null,"last_name":"Jarvis","page_name":"DevraJarvis","domain_name":"wsu","created_at":"2015-07-10T02:44:02.203-07:00","display_name":"Devra Jarvis","url":"https://wsu.academia.edu/DevraJarvis"},"attachments":[{"id":44850498,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/44850498/thumbnails/1.jpg","file_name":"The_agricultural_biodiversity_policy_dev20160418-20998-cbwe4m.pdf","download_url":"https://www.academia.edu/attachments/44850498/download_file?st=MTczNDAyNzM2Miw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"The_agricultural_biodiversity_policy_dev.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/44850498/The_agricultural_biodiversity_policy_dev20160418-20998-cbwe4m-libre.pdf?1460979465=\u0026response-content-disposition=attachment%3B+filename%3DThe_agricultural_biodiversity_policy_dev.pdf\u0026Expires=1733835579\u0026Signature=KcKdTv19E8hAZKvHO6Y2NIu4L86jKg5Nh65Pn-M1DBroi4wOUbF73P5sbJDW8mCGGRF2uc3~FCE0hryztww51bGam88i9E203p2d6Yu8J2yrMd9XGPje89Ru7FUY5WXoVy4vBndjX6jXHvl5HLyJp~QxltcutOSF6KM9KqZ98krNRsPd6lF7u8eWXAzFYnWSdFNGwm2lkhY14LDf2hkp2WUzkAHq-MOAsr3ofKIbVpLkvwxTSWnEEDwpY-HSXfBfTtf2V7jr-4pU8QwTXAyLTooGQgReXHxbGZ6avlSuL~6H7QUqJ4xQzzWnvrkW3P0i-xijWIycflxTVDI4QEW5JQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":7451,"name":"Information Policy","url":"https://www.academia.edu/Documents/in/Information_Policy"},{"id":10722,"name":"Policy Development","url":"https://www.academia.edu/Documents/in/Policy_Development"},{"id":11975,"name":"Peru","url":"https://www.academia.edu/Documents/in/Peru"},{"id":16655,"name":"Vietnam","url":"https://www.academia.edu/Documents/in/Vietnam"},{"id":33125,"name":"Work Environment","url":"https://www.academia.edu/Documents/in/Work_Environment"},{"id":43028,"name":"Genetic Diversity","url":"https://www.academia.edu/Documents/in/Genetic_Diversity"},{"id":47884,"name":"Biological Sciences","url":"https://www.academia.edu/Documents/in/Biological_Sciences"},{"id":48494,"name":"Biodiversity Conservation","url":"https://www.academia.edu/Documents/in/Biodiversity_Conservation"},{"id":58054,"name":"Environmental Sciences","url":"https://www.academia.edu/Documents/in/Environmental_Sciences"},{"id":81403,"name":"Burkina Faso","url":"https://www.academia.edu/Documents/in/Burkina_Faso"},{"id":180836,"name":"Design Tool","url":"https://www.academia.edu/Documents/in/Design_Tool"},{"id":687951,"name":"Farm management","url":"https://www.academia.edu/Documents/in/Farm_management"},{"id":821516,"name":"Decision Maker","url":"https://www.academia.edu/Documents/in/Decision_Maker"},{"id":904692,"name":"Bottom Up","url":"https://www.academia.edu/Documents/in/Bottom_Up"}],"urls":[{"id":7026442,"url":"https://www.researchgate.net/profile/Bhuwon_Sthapit/publication/254221321_The_agricultural_biodiversity_policy_development_process_Exploring_means_of_policy_development_to_support_the_on-farm_management_of_crop_genetic_diversity/links/54578c300cf2bccc49109031.pdf"}]}, dispatcherData: dispatcherData });

Finally, the study implies that the cost-effective means of promoting and sustaining on-farm conservation programmes is to target them in market isolated geographic locations of high crop diversity where farm households have more heterogeneity of agroecological conditions and more active family adult labour working on-farm.","owner":{"id":32955890,"first_name":"Devra","middle_initials":null,"last_name":"Jarvis","page_name":"DevraJarvis","domain_name":"wsu","created_at":"2015-07-10T02:44:02.203-07:00","display_name":"Devra Jarvis","url":"https://wsu.academia.edu/DevraJarvis"},"attachments":[{"id":44850467,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/44850467/thumbnails/1.jpg","file_name":"socioeconomic_and_agroecological_determinants_conservin.pdf","download_url":"https://www.academia.edu/attachments/44850467/download_file?st=MTczNDAyNzM2Miw4LjIyMi4yMDguMTQ2&st=MTczNDAyNzM2MSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Socioeconomic_and_Agroecological_Determi.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/44850467/socioeconomic_and_agroecological_determinants_conservin-libre.pdf?1460979466=\u0026response-content-disposition=attachment%3B+filename%3DSocioeconomic_and_Agroecological_Determi.pdf\u0026Expires=1734030961\u0026Signature=RXd147YMHtm8F2i9kQMq4~qqGyYkkuzckZG4YVF~wheLQC5xBSeaGZMrZUVtovsNwkApB0Z-6lYk-3-oEddTJ3Pupxf6oIHh67jnrLU3ZyeHZ7R3GVceYAodzZEvzjhOwF1tWBinbRLx8peFbf5EvTyabct0g3eOdI7wyVDHRL8l3PuzDvT6rTNfqnKxnR00Wi7qQq~oiH7S~oO7mXyMVCK42s4gCoNsXOIlIu87nLc2nuv7dJ35ED5bUcFHgoNDb4iGjuVEh1RVtmnx2YDnyXQi1r7nfbeGdu0w7Zio5qMT5rLP63QuK-4jh2w4eW~i-YXBNC~-OcbuO03gli1WdQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":165565,"name":"Cost effectiveness","url":"https://www.academia.edu/Documents/in/Cost_effectiveness"},{"id":467419,"name":"Womens' role in household decision-making","url":"https://www.academia.edu/Documents/in/Womens_role_in_household_decision-making"},{"id":586327,"name":"Household Survey","url":"https://www.academia.edu/Documents/in/Household_Survey"},{"id":978092,"name":"Diversity Indices","url":"https://www.academia.edu/Documents/in/Diversity_Indices"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="13874928"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/13874928/Challenges_to_agroecosystem_management"><img alt="Research paper thumbnail of Challenges to agroecosystem management" class="work-thumbnail" src="https://attachments.academia-assets.com/44850482/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/13874928/Challenges_to_agroecosystem_management">Challenges to agroecosystem management</a></div><div class="wp-workCard_item wp-workCard--coauthors"><span>by </span><span><a class="" data-click-track="profile-work-strip-authors" href="https://wsu.academia.edu/DevraJarvis">Devra Jarvis</a> and <a class="" data-click-track="profile-work-strip-authors" href="https://independent.academia.edu/JennieBarron">Jennie Barron</a></span></div><div class="wp-workCard_item"><span>Managing water and agroecosystems for food security</span><span>, 2013</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">As growth in population, gross domestic product (GDP) and consumption continues, further demands ...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">As growth in population, gross domestic product (GDP) and consumption continues, further demands are placed on land, water and other resources.

Measurements of richness, evenness, and divergence showed that considerable crop genetic diversity continues to be maintained on farm, in the form of traditional crop varieties. Major staples had higher richness and evenness than nonstaples. Variety richness for clonal species was much higher than that of other breeding systems. A close linear relationship between traditional variety richness and evenness (both transformed), empirically derived from data spanning a wide range of crops and countries, was found both at household and community levels. Fitting a neutral ''function'' to traditional variety diversity relationships, comparable to a species abundance distribution of ''neutral ecology,'' provided a benchmark to assess the standing diversity on farm. In some cases, high dominance occurred, with much of the variety richness held at low frequencies. This suggested that diversity may be maintained as an insurance to meet future environmental changes or social and economic needs. In other cases, a more even frequency distribution of varieties was found, possibly implying that farmers are selecting varieties to service a diversity of current needs and purposes. Divergence estimates, measured as the proportion of community evenness displayed among farmers, underscore the importance of a large number of small farms adopting distinctly diverse varietal strategies as a major force that maintains crop genetic diversity on farm.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="4f2fd5e86842effa17c6e5fd68a2173d" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":44850511,"asset_id":13874925,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/44850511/download_file?st=MTczNDAyNzM2Miw4LjIyMi4yMDguMTQ2&s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="13874925"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="13874925"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 13874925; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=13874925]").text(description); $(".js-view-count[data-work-id=13874925]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 13874925; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='13874925']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 13874925, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "4f2fd5e86842effa17c6e5fd68a2173d" } } $('.js-work-strip[data-work-id=13874925]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":13874925,"title":"A global perspective of the richness and evenness of traditional crop-variety diversity maintained by farming communities","translated_title":"","metadata":{"grobid_abstract":"Varietal data from 27 crop species from five continents were drawn together to determine overall trends in crop varietal diversity on farm.

Measurements of richness, evenness, and divergence showed that considerable crop genetic diversity continues to be maintained on farm, in the form of traditional crop varieties. Major staples had higher richness and evenness than nonstaples. Variety richness for clonal species was much higher than that of other breeding systems. A close linear relationship between traditional variety richness and evenness (both transformed), empirically derived from data spanning a wide range of crops and countries, was found both at household and community levels. Fitting a neutral ''function'' to traditional variety diversity relationships, comparable to a species abundance distribution of ''neutral ecology,'' provided a benchmark to assess the standing diversity on farm. In some cases, high dominance occurred, with much of the variety richness held at low frequencies. This suggested that diversity may be maintained as an insurance to meet future environmental changes or social and economic needs. In other cases, a more even frequency distribution of varieties was found, possibly implying that farmers are selecting varieties to service a diversity of current needs and purposes. Divergence estimates, measured as the proportion of community evenness displayed among farmers, underscore the importance of a large number of small farms adopting distinctly diverse varietal strategies as a major force that maintains crop genetic diversity on farm.","owner":{"id":32955890,"first_name":"Devra","middle_initials":null,"last_name":"Jarvis","page_name":"DevraJarvis","domain_name":"wsu","created_at":"2015-07-10T02:44:02.203-07:00","display_name":"Devra Jarvis","url":"https://wsu.academia.edu/DevraJarvis"},"attachments":[{"id":44850511,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/44850511/thumbnails/1.jpg","file_name":"A_global_perspective_of_the_richness_and20160418-9244-kyuark.pdf","download_url":"https://www.academia.edu/attachments/44850511/download_file?st=MTczNDAyNzM2Miw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"A_global_perspective_of_the_richness_and.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/44850511/A_global_perspective_of_the_richness_and20160418-9244-kyuark-libre.pdf?1460979692=\u0026response-content-disposition=attachment%3B+filename%3DA_global_perspective_of_the_richness_and.pdf\u0026Expires=1733852926\u0026Signature=a5fBIs4PNa8EVfW6ZIkk4-cqlKniVIPhEeEqcwpCkcyldi~xwDO1NM8GcQqejiTQ-XjDF9t6sXPD0-~9N7N0SuJ0YphcrtvJQSp-HKojR1bZmS0tQTLDBDad1VLiHho1FHDvy21GkW0KLEBYPqXRw7ntT2x4lumaB2nyszOY22yqvw8nm~30-Qi4mbgCak2LIKM2Jt9GM9a0SEL4C1kLr1PaxWQEI8LRh3ZYbQcYa3eAou06Zxnn2Pl4FenBXAcn51QQG4VQjqjJa-iOOub31izJr1AF84oMSXdaOjS9oRTzv-tDfvr2QqMmnvQP2-20OHzOEOFdhkuegeFaMHKQYA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":9846,"name":"Ecology","url":"https://www.academia.edu/Documents/in/Ecology"},{"id":17825,"name":"Biodiversity","url":"https://www.academia.edu/Documents/in/Biodiversity"},{"id":28157,"name":"Environmental Change","url":"https://www.academia.edu/Documents/in/Environmental_Change"},{"id":28235,"name":"Multidisciplinary","url":"https://www.academia.edu/Documents/in/Multidisciplinary"},{"id":30372,"name":"Low Frequency","url":"https://www.academia.edu/Documents/in/Low_Frequency"},{"id":43028,"name":"Genetic Diversity","url":"https://www.academia.edu/Documents/in/Genetic_Diversity"},{"id":45213,"name":"Italy","url":"https://www.academia.edu/Documents/in/Italy"},{"id":1005211,"name":"Breeding System","url":"https://www.academia.edu/Documents/in/Breeding_System"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="13874924"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/13874924/Wild_relatives_and_crop_cultivars_detecting_natural_introgression_and_farmer_selection_of_new_genetic_combinations_in_agroecosystems"><img alt="Research paper thumbnail of Wild relatives and crop cultivars: detecting natural introgression and farmer selection of new genetic combinations in agroecosystems" class="work-thumbnail" src="https://attachments.academia-assets.com/44850488/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/13874924/Wild_relatives_and_crop_cultivars_detecting_natural_introgression_and_farmer_selection_of_new_genetic_combinations_in_agroecosystems">Wild relatives and crop cultivars: detecting natural introgression and farmer selection of new genetic combinations in agroecosystems</a></div><div class="wp-workCard_item"><span>Molecular Ecology</span><span>, 1999</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Whether new combinations of genes that result from hybridization and introgression between wild a...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">Whether new combinations of genes that result from hybridization and introgression between wild and cultivated taxa are maintained, with the resultant development of populations with new characteristics, depends on natural selection, and in the case of crops, on human selection.

While many cases of deliberate introgression of desirable traits into crop cultivars as part of breeding programmes are known, the extent and significance of natural or farmer-assisted introgression is uncertain. A range of techniques have been used to document natural hybridization and introgression of agricultural crops and their wild relatives in many crops including maize, wheat, barley, oats, pearl millet, foxtail millet, quinoa, hops, hemp, potato, cocona, casava, common bean, cowpea, pigeon pea, carrots, squash, tomato, radish, letuce, chilli, beets, sunflower, cabbage, and rasberries. However, the majority of these studies are based on morphological characters, and few have investigated the frequency with which such new types are produced and retained in natural and agroecosystems for farmer selection. Even more limited is information on the role of farmers in recognizing and selecting new genetic variation from the natural introgression of crops with their wild relatives, and the impact, once selected, of these new genetic combinations on the crop diversity. Molecular evaluation of natural introgression linked to investigations of farmer recognition and use of introgressed types provide ways of evaluating whether farmer selection for introgressed types is a significant process in increasing the genetic diversity of crop plants.","owner":{"id":32955890,"first_name":"Devra","middle_initials":null,"last_name":"Jarvis","page_name":"DevraJarvis","domain_name":"wsu","created_at":"2015-07-10T02:44:02.203-07:00","display_name":"Devra Jarvis","url":"https://wsu.academia.edu/DevraJarvis"},"attachments":[{"id":44850488,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/44850488/thumbnails/1.jpg","file_name":"Wild_relatives_and_crop_cultivars_detect20160418-7107-1p6jpt5.pdf","download_url":"https://www.academia.edu/attachments/44850488/download_file?st=MTczNDAyNzM2Miw4LjIyMi4yMDguMTQ2&st=MTczNDAyNzM2MSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Wild_relatives_and_crop_cultivars_detect.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/44850488/Wild_relatives_and_crop_cultivars_detect20160418-7107-1p6jpt5-libre.pdf?1460979467=\u0026response-content-disposition=attachment%3B+filename%3DWild_relatives_and_crop_cultivars_detect.pdf\u0026Expires=1734030961\u0026Signature=O59zzxbQ4b~jSLZLsZm9e-9gtSL8~MbRgoQxr91t7E65oZhALuoc~1WRhKALueq7-xBjxArQAXycfL-5dJJTr3qVatWkZwBOM3YgsHCUjt0JVKEza3N2GB1bzBlX47mIRXBgvwJ3~4~kqZNam1vzwopXqAT7OZ~bt10iUCvDEzeVT6VHbHSGMu8FgpfNzcuws7c3N6BYNA~jWTcdUZz-xIbcgSFTmKn0pCI6W7FXw9GNUohQuT6STWsl4yK-qy3cCRsADEko-inlItG3e43o~Dn0eHMCR5xutS6pnYMsubpmbA8~IiQI7I-7BRERfZqzJvWAxhfveopfI~YgX3884g__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":156,"name":"Genetics","url":"https://www.academia.edu/Documents/in/Genetics"},{"id":46119,"name":"Molecular Ecology","url":"https://www.academia.edu/Documents/in/Molecular_Ecology"},{"id":47884,"name":"Biological Sciences","url":"https://www.academia.edu/Documents/in/Biological_Sciences"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="13874923"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/13874923/The_agricultural_biodiversity_policy_development_process_Exploring_means_of_policy_development_to_support_the_on_farm_management_of_crop_genetic_diversity"><img alt="Research paper thumbnail of The agricultural biodiversity policy development process: Exploring means of policy development to support the on-farm management of crop genetic diversity" class="work-thumbnail" src="https://attachments.academia-assets.com/44850499/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/13874923/The_agricultural_biodiversity_policy_development_process_Exploring_means_of_policy_development_to_support_the_on_farm_management_of_crop_genetic_diversity">The agricultural biodiversity policy development process: Exploring means of policy development to support the on-farm management of crop genetic diversity</a></div><div class="wp-workCard_item wp-workCard--coauthors"><span>by </span><span><a class="" data-click-track="profile-work-strip-authors" href="https://wsu.academia.edu/DevraJarvis">Devra Jarvis</a> and <a class="" data-click-track="profile-work-strip-authors" href="https://independent.academia.edu/FaddaC">C.

Genetic diversity gives a species or a population the ability to adapt to changing environments. For resource-poor farmers, adaptive animal breeds, crop varieties and cultivars adapted to particular micro-niches, stresses or uses are the main resources available to maintain or increase production and provide a secure livelihood. The economic value of genetic diversity for productivity and yield traits is discussed in the literature. However, it is diffi cult to value many other aspects of agricultural biodiversity as these have both direct and indirect values in terms of qualitative traits such as food, nutrition and environmental uses that include adaptation to low input conditions, co-adaptive complexes, yield stability and the consequent reduction of risk, specifi c niche adaptation, and in meeting socio-cultural needs. Together, the direct and indirect values of genetic resources for resource-poor farmers are expressed in a range of options in the form of the crop varieties and species they use for managing changing environments.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="230357b2a8cdcd2cc9efd5fcaf9e119f" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":44850523,"asset_id":13874922,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/44850523/download_file?st=MTczNDAyNzM2Miw4LjIyMi4yMDguMTQ2&st=MTczNDAyNzM2Miw4LjIyMi4yMDguMTQ2&s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="13874922"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="13874922"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 13874922; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=13874922]").text(description); $(".js-view-count[data-work-id=13874922]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 13874922; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='13874922']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 13874922, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "230357b2a8cdcd2cc9efd5fcaf9e119f" } } $('.js-work-strip[data-work-id=13874922]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":13874922,"title":"The value of plant genetic diversity to resource-poor farmers in Nepal and Vietnam","translated_title":"","metadata":{"grobid_abstract":"Genetic resources for food and agriculture are the biological basis of world food and nutrition security; and they directly or indirectly support the livelihoods of over 2.5 billion people.

Published findings regarding prospects for on farm conservation as economies develop are summarized and empirical examples of suitable policies to support farmers' decisions are placed in the context of economics principles.","owner":{"id":32955890,"first_name":"Devra","middle_initials":null,"last_name":"Jarvis","page_name":"DevraJarvis","domain_name":"wsu","created_at":"2015-07-10T02:44:02.203-07:00","display_name":"Devra Jarvis","url":"https://wsu.academia.edu/DevraJarvis"},"attachments":[{"id":44850496,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/44850496/thumbnails/1.jpg","file_name":"Economic_concepts_for_designing_policies20160418-9244-8exp6y.pdf","download_url":"https://www.academia.edu/attachments/44850496/download_file?st=MTczNDAyNzM2Miw4LjIyMi4yMDguMTQ2&st=MTczNDAyNzM2Miw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Economic_concepts_for_designing_policies.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/44850496/Economic_concepts_for_designing_policies20160418-9244-8exp6y-libre.pdf?1460979466=\u0026response-content-disposition=attachment%3B+filename%3DEconomic_concepts_for_designing_policies.pdf\u0026Expires=1734030962\u0026Signature=b-d5WOD18f8QSiWRVr1qFk9YGoBUfXFp1aljPOR-JJeo2IAc~~qiSp078c~ysCGkxtl9I~SmVvaw~2XY71dclQ5dAHDTM6wVBhovABEve5Kz~AiXgPjouzPvKH-4f5D-WKvvCj~kewupbIDmadJdKkMGhwQR49CFPLkjfIFXSoiOx82AQ35OdsSODrLefWC49YzJKL5-Hdp4Gb7M7semVQJNPdp5KtxOFp29hlybdS8P0jxvXMRs2ISnBExT~jLGQYMAggR1f93oiskGJV~0xNvcVt6nBX7NMp7RdsUoZPz3fHW1sWTfybUX7KwipFsOtKQz0L1JRxBTp34oZXC6Yg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":14934,"name":"Agricultural Biotechnology","url":"https://www.academia.edu/Documents/in/Agricultural_Biotechnology"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="13874920"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/13874920/Rice_landrace_diversity_in_Nepal_Socio_economic_and_ecological_factors_determining_rice_landrace_diversity_in_three_agro_ecozones_of_Nepal_based_on_farm_surveys"><img alt="Research paper thumbnail of Rice landrace diversity in Nepal.

This study was undertaken to test whether features of the traditional seed system can significantly influence the diversity of a crop and its conservation on-farm. In Jumla (high-hill), the barley seed system is completely informal and is mainly from farmer to farmer. In the present study, the seed flows and the pattern of genetic diversity in barley were investigated to detect differences between the two varieties and test the divergence among populations of each variety These data suggested that Chawali, the more common variety, was less subject to homogenising gene flow between farms than was Lekali. A total of 128 farming households were surveyed for seed supply information and 128 populations for each landrace from two villages: Kartikswami and Talium were collected for SSR diversity analysis. Some 92 SSRs were screened in an initial sample of 20 barley populations of both landraces and 2 improved varieties (LG-51 and Soluwa). Of the 81 SSRs that consistently amplified, only 15 SSRs (19%) were polymorphic with gene diversity values ranging from 0.09 to 0.71. A medium to low diversity was detected among the landrace populations of barley varieties. Chawali populations were less polymorphic within ecological groups, and more divergent between than were Lekail populations. This result accords with Chawali having a more conservative local seed system.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="a149324055a99f0ad7fd68ebf74f36c8" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":44850501,"asset_id":13874919,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/44850501/download_file?st=MTczNDAyNzM2Miw4LjIyMi4yMDguMTQ2&st=MTczNDAyNzM2Miw4LjIyMi4yMDguMTQ2&s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="13874919"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="13874919"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 13874919; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=13874919]").text(description); $(".js-view-count[data-work-id=13874919]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 13874919; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='13874919']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 13874919, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "a149324055a99f0ad7fd68ebf74f36c8" } } $('.js-work-strip[data-work-id=13874919]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":13874919,"title":"Traditional seed management and genetic diversity in barley varieties in high-hill agro-ecosystems of Nepal","translated_title":"","metadata":{"grobid_abstract":"Chawali and Lekali are two common farmer's barley varieties or landraces in Jumla, Nepal (2,240-3,000 m) with small to bold grains and wide adaptation from irrigated low lands to high hills.

This study was undertaken to test whether features of the traditional seed system can significantly influence the diversity of a crop and its conservation on-farm. In Jumla (high-hill), the barley seed system is completely informal and is mainly from farmer to farmer. In the present study, the seed flows and the pattern of genetic diversity in barley were investigated to detect differences between the two varieties and test the divergence among populations of each variety These data suggested that Chawali, the more common variety, was less subject to homogenising gene flow between farms than was Lekali. A total of 128 farming households were surveyed for seed supply information and 128 populations for each landrace from two villages: Kartikswami and Talium were collected for SSR diversity analysis. Some 92 SSRs were screened in an initial sample of 20 barley populations of both landraces and 2 improved varieties (LG-51 and Soluwa). Of the 81 SSRs that consistently amplified, only 15 SSRs (19%) were polymorphic with gene diversity values ranging from 0.09 to 0.71.

A baseline survey in Jumla, a high-altitude site (2200-3000 m), identified rice landraces with different names that differed in phenotype and were adapted to the extreme high-altitude environment. Jumli Marshi was the most common traditional rice variety, accounting for 85% of samples collected. The genetic diversity of these landraces was assessed by agro-morphological variability and microsatellite marker polymorphism. Forty-two qualitative and quantitative traits and 39 microsatellite (simple sequence repeats, SSR) markers were assessed among accessions with 10 different names. The accessions showed low morphological diversity with an average Shannon Weaver diversity index of 0.23. Only 16 morphological traits showed significant variation among the accessions. Discriminant function analysis showed that only 36% of accessions could be clustered according to name by morphological traits. Only one SSR locus was polymorphic, distinguishing only one accession. The names used by farmers to describe the phenotypic characteristics of panicle and grains were inconsistent indicators of genetic identity. We conclude that the Jumla landrace population has a narrow genetic base.
