This study was executed to assess the twenty-one single cross maize hybrids with three local checks
(BHM-12, BHM-13 and BHM-14) in five locations of Bangladesh for its adaptability and stability
and also to study the genotypes and environment interaction. Yield data of twenty-four maize hybrids
was analyzed through the additive main effects and multiplicative interaction (AMMI) and GGE
biplot methods. Considering the grain yield, bi~1 and S2 di~0 value, it was observed that G10 and G16
were the higher yielding and suitable across the environments. On the other hand, G20 and G14 were
higher yielding but were responsive to favorable environments. Among the five locations, the
environment of Hathazari was the poorest, whereas Barishal and Dinajpur were the most favorable
environments for maize production. When hybrids were compared with ideal genotypes, it was
observed that G14, G16, G10, and G20 were closed to the ideal genotypes so that they can be more
desirable than other tested hybrids. The AMMI biplot indicated that G24, G16, G13, G17 and G14
were positioned adjacent to the biplot’s origin which indicated their stability in performance across
environments. Finally, stability analysis with the help of GGE and AMMI statistics identified two
hybrids G14 and G16 that could be used as reference for future crop improvement program.
