This research evaluated the adaptability of diverse wheat genotypes from a broad region under varying agroecological conditions during two growing seasons using principal component analysis and hierarchical cluster analysis. The results revealed significant genotype × environment interactions, with grain weight per plant being the most sensitive trait to rainfall deficit. Certain genotypes demonstrated high adaptability across both favorable and unfavorable conditions, highlighting their potential value in wheat breeding programs aimed at improving stress tolerance and yield stability.
