Abstract

This study aimed to assess the performance of six bread wheat genotypes introduced by a national wheat research program. These genotypes were sown at four planting dates 20^thOctober, 10^th November (recommended), 30^th November and 20^th December during two winter seasons of 2019/2020 and 2020/2021. The separate experiments were arranged in a randomized complete block design with four replications in each environment. The combined analysis of variance showed that mean squares due to environments were highly significant for number of spikes m^-2, 1000-kernel weight as well as grain yield (ard/fed) this result indicated that the studied genotypes exhibited different effect from environment to other. Mean squares due to genotypes x environments were highly significant for all studied traits except number of spikes/m². Parameters of phenotypic stability indicated that wheat genotypes Giza 171 and Misr3 are considered a stable verity for studied environments for grain yield (ard/fed), respectively, where had a coefficient of regression don’t significantly differ from one and less amount of S²di and adapted.
