Application of genotype by environment (G × E) interaction would be used for identifying optimum test condition of the varietal adaptation in the establishment of breeding purpose. Yield and yield components were used to perform additive main effect and multiplicative interac-tion (AMMI) analysis. Significant difference for G × E interaction were observed for all variable examined. For yield, 0.18 of total sum of squares corresponded to G × E interaction. Correlation analysis was carried out between genotypic scores of the first interaction principal compon-ent axis (IPCA 1) for agronomic characters. Significant correlations were observed between IPCA 1 for yield and capsule bearing stem length (CBSL), number of capsule per plant (NOC). The biplot of grain yield means for IPCA1 which accounted for 34% of the variation in total treatment sums of squares showed different reaction according to G × E interaction, genotypes and environments. Taegu showed relatively lower positive IPCA1 scores, and it also showed smaller coefficient variation of yield mean where it is reco-mmendable as a optimal site for the sesame cultivar adap-tation and evaluation trial. In case of variables, Yangbaek and M1 showed relatively lower IPCA1 scores, but the score direction showed opposite each other on the graph. Ansan, Miryang1, Miryang4, and Miryang6 seemed to be similar group in view of yield response against IPCA1 scores. These results will be helpful to select experimental site for sesame in Korea to minimize G × E interaction for the selection of promising genotype with higher stability.
