Abstract

In order to evaluate GENETIC VARIATION and response of spring WHEAT genotypes to different environmental conditions, sixteen WHEAT genotypes (including 4 durum WHEAT and 12 bread WHEAT genotypes) were examined in optimum and post-an thesis DROUGHT STRESS conditions in two separate experiments using Randomized Compete Block design with four replications. Results showed that environmental effect was significant for grain harvest index (GHI) and thousand grain weight (TGW) at 5 and 1% probability levels, respectively. Genotypic difference for GRAIN YIELD (GY), TGW, GHI and biological yield (BY) were found significant. There were significant correlation between GY and GHI at the 1% probability level in both optimum and DROUGHT STRESS conditions. The highest similarity value in traits changes obtained from GY and BY based on variable cluster analysis. Coefficients differences of GENETIC VARIATION of traits were not significant in DROUGHT STRESS condition, while there were significant GENETIC VARIATION for GY, BY and GHI in optimum condition. Generally, it seems that interaction effects of internal processes of plant, specially relationship between sink - source may lead movement and accumulation of dry matter in to grain.
