EVALUATION OF MAIZE HYBRIDS SUITABLE FOR DIFFERENT AGRO-ECOLOGICAL REGIONS OF BANGLADESH BY USING GGE –BIPLOT AND AMMI MODEL ANALYSIS (Pages : 1 - 5)

Evaluation of the productivity and performance of maize hybrid in variable environment is a basic demand for releasing verities. The present study assessed genotype × environment interaction and stability for grain yield, plant height and ear height of 15 maize hybrids in 5 different agro ecological regions of Bangladesh during 2016-17. The GGE Biplot and AMMI model (additive main effects and multiplicative interaction) analysis were used to assess the genotype-environment interactions over five locations to select the hybrid having higher yield and other potential attributes. A significant variation for genotypes (G), environment (E) and GEI were observed for the yield and its related characters. Among these tested environments, Gazipur, Ishurdi and Jamalpur were found not suitable to get desirable yields for all tested genotypes; but Rangpur and Barisal were found suitable for the production of maize hybrid. Among the suited two locations, Rangpur was found highly suitable for hybrid maize cultivation followed by Barisal. Considering the mean, bi and S2di, all the hybrids showed different responses of adaptability under different environmental conditions. Among the hybrids, A-9×B-19, BARI hybrid maize-9, 981, 7074/S5-15×M-10, and 7074/S5-15×M-15 exhibited the higher grain yield, bi~1 and S2di~0 indicated that the hybrids are stable across the environment.Download
