RESUMO:

Upland rice breeding programs aim to develop high-yielding and stable genotypes across diverse environments. This study evaluated the genetic potential of upland rice lines under multiple environmental conditions using BLUP-RE, Mahalanobis distance clustering, and GGE Biplot analysis. The results highlighted significant genotype × environment (G×E) interactions, reinforcing the need for selection strategies that prioritize both yield potential and phenotypic stability. Genotypes such as AB112158 and CMG1590 exhibited high productivity and broad adaptability, while cv. Primavera showed lower performance, suggesting that the evaluated environments were affected by water stress conditions and high temperature. Environmental classification identified four distinct mega-environments, optimizing genotype recommendations based on this specific agroclimatic conditions. The GGE Biplot analysis confirmed the importance of selecting genotypes with high stability and responsiveness, ensuring greater yield predictability under variable conditions. The findings underscore the importance of integrated breeding approaches for upland rice, focusing on yield stability and adaptability. These strategies are essential to enhance food security and agricultural sustainability in Central Brazil.
