The present study was performed to analyze the Genotype-Environment (G x E) interaction for 21 maize hybrids over 3 locations to identify suitable and stable hybrids. Grain yield data were subjected to the AMMI analysis. Analysis revealed significant G x E interaction which could be attributed to differential ranking of the genotypes across the environments. The G x E interaction was further axis captured into PCA axes, of which the first PCA 52–69% to the total G x E variance. Perusal of the biplot analysis indicated that five hybrids Viz., Seed tech, Super-36, Vivek QPM-9, Prakash and Vivek hybrid-33 were identified as having general adaptability with high mean yields and PCA scores nearer to zero.
