| Abstract | ||||
| The present investigation was carried out at the experimental farm of Sids and West west El-Minya Research Stations to evaluate the yield productivity of 16 bread wheat varieties during the two growing seasons of 2018/2019 and 2019/2020. The experimental design used was a randomized complete block design (RCBD) with three replicates. Four stress tolerance indices were calculated using the grain yield under Sids location as favorable environment and West west El-Minya location as a stress environment. The genotype by trait GxT biplot graph was automated to compare wheat varieties in terms of their multiple traits for each location separately. Results showed significant differences among wheat varieties, growing regions and their interaction for most studied traits across the two seasons. The grain yields produced under West west El-Minya region were slightly lower compared to that produced under Sids region indicating that the West west El-Minya is promising region for future wheat cultivation despite its stress conditions. It is revealed that Gemmeiza 9, Gemmeiza 10, Giza 171 and Shandaweel 1 had the maximum grain yields across the two growing regions. In addition, they recorded the highest values of the four tolerance indices. It is obvious that Sids 1, Giza 171, Misr 2 and Shandaweel 1 reflected the best performance in terms of most studied traits under West west El-Minya region while Sids 14, Shandaweel 1, Sakha 95 and Giza 171 were the best varieties under Sids conditions. It is obvious that GxT biplot graph is considered an easy and effective visual to interpret results. | ||||
