A COMPARISON of ten local and twelve introduced wheat accessions was performed on twelve different induced environments (2 years × 2 sowing dates × 3 water stresses) to analyze genotype × environment interactions (G×E) and estimate stability indices of yield and its components. Mainly the total variations of studied traits were due to the main effects of environmental factors and their interaction, whereas the significant environmental variations were ranged from 10.62% (harvest index) to 43.95% (spike kernels weight). The genotypes differed significantly for all studied traits, moreover these differences ranged from 6.82 % to 50.42% of total variation in 1000-kernel weight and no. of kernels/spike, respectively. G×E interactions were highly significant and their contributions to the total SS accounted for 40.17, 30.78, 18.17, 22.02, 25.46, 18.61 and 88.46% for heading date, no. of spikes/m2, no. of kernels/spike, spike kernel weight, 1000-kernel weight, grain yield/m2 and harvest index, respectively. Three genotypes (NGB10893, Sids1 and Giza168) were high yielding and stable for most of the studied traits. Thus, these three genotypes could be promoted to the next extensive breeding programs.
