[email protected] Abstract: The interaction of genotype by the environment is very common in multi-environment trials of maize hybrids. This study evaluates the quantity and the quality of grain production and the stability of four maize genotypes in a field experiment that was conducted in five different locations for two years. In order to make a reliable evaluation of the performance of genotypes in the environ- ments, principal components analysis (PCA) was used to investigate the correlation of the yield, soil Citation: Katsenios, N.; Sparangis, P.; properties and quality characteristics, while the additive main effects and multiplicative interaction Chanioti, S.; Giannoglou, M.; (AMMI) analysis detected the narrow adaptations of genotypes at specific mega-environments. For Leonidakis, D.; Christopoulos, M.V.; the yield, AMMI analysis indicated that a group of five environments (ENV1, ENV8, ENV6 ENV10 Katsaros, G.; Efthimiadou, A.
