Applications of AMMI model in cereals

The AMMI analysis provided a better understanding of the GEI through analysis of variance facilitated identification of genotypes possessing stable yields as well as discriminating environments through the biplot display and specificity in adaptability of the genotypes to specific environments.GGE biplot analysis is an effective tool to four achieve understanding about i) investigation of possible mega-environment differentiation in the target environment ii) Selection of superior cultivars for individual mega-environments iii) Selection of better test environments and iv) development of a better understanding of the genotype in to environment.
