Abstract

Terminal HEAT AND DROUGHT STRESS, are the common results during wheat growth, in subtropical and semi arid climates such as Khuzestan province. This study was carried out in randomized complete block design with three replications and twenty five SPRING WHEAT genotypes for evaluating, heat stress , normal and late planting at Ahwaz, and water stress, full irrigation and lost anthesis drought at Behbahan research station during two years 1994-95 and 1995-96. Simple analysis of variance was conducted for seed number per square meter (SN), seed weight (SW), seed yield (SY), and multiple analysis of variance between both environments. Since the comparison of an average of factors may be an unsuitable index in stress condition for tolerance determination, and in order to reciprocate effects between genotype and environment, STABILITY ANALYSIS was conducted, and genotype responses in all environments was computed based on regression definition (R), standard deviation (S2d), coefficient of determination (R2), and genotypes means. Results showed that the regression analysis, the stress susceptibility index (SSI), and SY identified the genotypes tolerance to stress. The sever conditions, HEAT AND DROUGHT STRESS, SN, SW, and SY 12, 13, and 28% respectively. The Attila genotype wheat, SSI=0.83, R=1.18, and SY=4807 kg/ha. Superior genotypes for terminal HEAT AND DROUGHT STRESS conditions, and the Fong wheat, SSI=0.45, R=0.68, and SY=4279 kg/ha., compatibility to severe conditions and it’s early maturity were recommended for late planting in Khuzestan.
