N2  - A study was conducted to identify maize hybrids with stable grain yield among 24 commercial hybrids in 5 test environments. The variation in genotypes, environments and genotype environment interaction (G x E) was significant. Maximum variation was explained by difference in environmental conditions (55.92%) and least by genotypes (9.81%). The 2 AMMI principal coordinates axes (PCA) estimates explained 80% of the phenotypic variation. For the quantitative measure of stability, AMMI Stability Value (ASV) was calculated using PCA scores. Among these hybrids HQPM-1 was found to be most stable with ASV of 0.32. Based on this experiment using various biplot methods, it is concluded that Hyderabad environment is best for testing the hybrids for wider adaptability and Karnal and Kanpur locations can be used to identify location specific hybrids. The hybrids G5 (TNAU Co-6), G14 (LVN 99) and G 18(VS 71) performed best in Udaipur, G23 (Bio 9544), G12 (VN 8960) and G21 (HTMH 5101 Sona) and G24 (Bio 9522 S) were found best in Hyderabad and Delhi. At Karnal G20 (900M Gold), G6 (PMH-1), G13 (LCH 9) and G22 (HTMH 5401) are considered to be the best genotypes whereas in Kanpur G7 (PMH-2), G11 (HQPM-1) and G 2 (WLS-F133-4-1-1-B-2-BBB/CL02450-BBB) were found to be best
