Abstract

The present study was carried out at three locations, i.e., Sakha, Sids, and Mataana Agricultural Research Stations, within two successive seasons (2020/2021 and 2021/2022), to evaluate eighteen promising faba bean genotypes derived from eleven crosses along with two commercial varieties, Giza 843 and Sakha 1. GGE model pattern analysis was used to determine stable faba genotypes for seed yield and to conceive of the relationships between environments and genotypes. Results of the combined analysis revealed that there were highly significant differences for genotypes and locations, indicating high genetic variability between genotypes and wide differences between locations. Comparing the check cultivars, Giza 843 had wide adaptability and produced a higher seed yield under Middle and Upper Egypt conditions, while Sakha 1 was superior under Sakha conditions. The new genotype G6 ranked first under all conditions and exceeded the average of the commercial cultivars by 9.8, 8.5, 11.6, and 10.0% under Sakha, Sids, Mataana, and the grand mean, respectively. GGE results revealed that the first principal components (PC1 and PC2) explained 83.57% of the total variation. The most stable genotypes were G6, G13, G15 and the check cultivar G1. These results suggested the release of G6 as a new faba bean cultivar for its wide adaptation and high productivity.
