Abstract
Among breeding program, releasing a new genotype with the desired yield stability and high performance under different environments is the main goal for wheat breeders. This study is aimed to identify the high adaptability and stability bread wheat genotypes with high yielding and resistance to yellow rust disease. Thus, twelve field experiments were conducted with 8 genotypes across 2 seasons (2019/2020 and 2020/2021) at 6 locations, viz. Skha, Etay-Elbaroud, Gemiza, Kafer El-Hamam, Matana and Nubaria in a randomized complete block design. The combined analysis of variance for grain yield cleared the significant effects of genotype (G), environment (E) and GE interaction, accounting for about 2.77%, 89.72%and 7.49% of the total variation, respectively. Additive main effect and multiplicative interaction (AMMI) analysis confirmed significant of the first two IPCA's and greatness the environmental variation. Genotype main effect plus GE interaction (GGE) biplot showed main two mega-environments, the first had most environments with winner stable genotype G3 (Line 3) as well as G1 (Line 1).Second mega-environment contained only two environments with winner check varieties. GGE biplot for the genotypes comparison, illustrated that genotypes G3 (Line 3) was found to be most adaptable and ideal stable across all tested environments, and then it should be recommended for releasing with wider environmental adaptability. Three molecular markers were used to evaluate the selected breeding materials for detecting the presence of different rusts resistance genes. Then, it can be used in the bread wheat breeding program to pyramid different resistance gene using Marker Assisted Selection (MAS).
