Genotypes T2 - International Journal of Agricultural and Biosystems Engineering SP - 352 EP - 356 VL - 5 SN - 1307-6892 UR - https://publications.waset.org/pdf/15516 PU - World Academy of Science, Engineering and Technology NX - Open Science Index 54, 2011 N2 - The objective of this experiment was to study of water relations and chlorophyll in different wheat genotypes and their correlations with grain and biological yields. 21 genotypes of bread wheat were compared in a field experiment as randomized complete blocks design with four replications. The results showed that relative water deficit, relative water loss, excised leaf water retention, cell membrane stability, chlorophyll-a, chlorophyll-b, total chlorophyll, grain yield and biological yield were different significantly among wheat genotypes, but SPAD-chlorophyll index, relative water content and chlorophyll florescence were not. Significant correlations were not observed among above mentioned water relations and chlorophyll characteristics with grain yield, but there was a positive and significant correlation between biological yield and grain yield.
