  • emerges. First, genotypes that combine high average yield with a more consistent response appear to be more suitable for general adaptation; in this study, WAASBY and GGE findings the closest candidate to this profile (Table 6; Figures 4a– 4b). Second, genotypes that provide a clear locations can be advantage evaluated for target-environment (specific) adaptation; the which-won-where view supports G3 in Konya conditions and G4 in Bursa (Figure 4b; Table 5). Therefore, recommendations should be presented as general and specific adaptation options, target, considering environmental risk profile, and resource conditions (especially water constraints), rather than attributing a “best everywhere” claim to a single genotype. production the 4.5.
