Superior grain quality is the main goal of rice breeders because of its high commercial value. Progress in selection for grain quality with yield in harsh environments is markedly affected by environmental variation. The genotype by environmental (G × E) interaction influence on grain quality was analyzed in this study, comprised of 17 rice hybrids grown in six location- year environments. The objective of this study was to examine the influence of G × E interaction for grain quality in hybrid rice by using AMMI model. Results of the trial revealed that grain quality was highly influenced by environmental factors and brings out the suitability of specific genotype to specific location/season through the biplot. On the other hand, external environmental variables can be regressed on the environmental scores to lead to a useful biological interpretation of the interaction effects, which is not possible in additive effect models. The implications of these results for rice hybrids on grain quality in varied environmental location are discussed.
