Stability Analysis for some Agronomic and Quality Characters of New Bread Wheat Genotypes under Multi Environmental Trials in Egypt

Trials conducted across multiple environments are critical for characterizing the ideal cultivar for diverse locations. This study aimed to assess the stability of twelve new bread wheat genotypes using certain agronomic and qualitative characteristics in four different agro-climate conditions in Egypt (Sakha, Nubaria, Sids and Shandaweel) in 2022/23 and 2023/24 seasons. To achieve these goals, AMMI, GGE and Eberhart and Russel methods were used. Environments, genotypes, their interaction and interaction principal component axis IPCA1 and IPCA2 showed significant mean squares for all the studied characters. The studied genotypes G7, Misr 3 and Sakha 95 combined stability using AMMI, GGE and Eberhart and Russel methods and the high grain yield. In addition, the genotype G9 showed the same trend for wet and dry gluten contents and protein content. Also, the genotype G2 was the highest one for grain yield as mean across the studied environments but did not show stability using the used methods.
