| Abstract | ||||
| Seven promising bread wheat lines at six different locations, represented different ecological zones obtained from the national wheat research program and were tested with two new commercial cultivars Misr3 and Sakha 95. in a yield trial in two successive seasons (2017/2018 and 2018/2019). The experimental design was a randomized complete block design with four replications. Stability parameters of grain yield were calculated for the new promising lines and the two commercial cultivars. The results showed that the genotypes G2, G4, G5, G6 and G7 did not differ significantly out yield the two checks cultivars, Misr3 and Sakha 95. Line G6 and Misr 3 showed more stability in grain yield compared to the other genotypes. GGE-biplot analysis showed that it is preferable to grow the genotype G 6 in the regions of Sakha, Sids and Shandaweel, and the cultivar Sakha 95 at Nubaria and Etay-El-Barood regions, while genotype G7 was the best when grown in El-Mattana area. The genotype G6 was considered an ideal genotype. | ||||
