Background Enhancing maize grain yield in tropical regions faces significant challenges due to variability agroclimate, soil conditions, and agroecosystems. Understanding genotype (G) by environment (E) interaction (GEI) plant breeding is crucial for selecting developing high-yielding genotypes adapted diverse environments. Methods Ten hybrids, including eight candidates two commercial varieties, were evaluated across ten environments Indonesia using a randomized complete block design with three replications. The GEI effect stability assessed statistics, additive main effects multiplicative model (AMMI), + × (GGE) biplot methods. Results Discussion Analysis of variance revealed effect, indicating differences hybrid responses (GY), allowing analysis. G01 showed the highest GY based on best linear unbiased prediction (BLUP) Correlation analysis indicated strong associations between statistics ( YS i S (6 ) GY, aiding selection hybrids. integration AMMI BLUP method, weighted average absolute scores (WAASB), enabled precise measurement stability. Overall, (R0211), G04 (R0105), G05 (R0118), G07 (R0641) emerged as high-yielding, stable hybrids AMMI, GGE biplot, WAASB rankings. These offer promising genetic improvement programs regions.
