Journal Article 2021 01 16 Sesame is one of the most important oil, industrial and medicinal plants that is cultivated in a large area of tropical and subtropical regions. In this study, fifteen sesame genotypes are cultivated to identify the superior genotypes in terms of yield and stability (minimum environmental impact) in four locations (Arak, Birjand, Karaj, and Shiraz) for two years. In combine variance analysis, effect of location, genotype and interaction effect of location × genotype were not significant.. The first and second main components of bipod analysis explained 84.06% and 8.40% (92.46% in total), of environment derived changes on genotypes, respectively. According to the plots, Arak, Birjand, and Shiraz genotypes had a high correlation in term of grain yield. The best genotypes in Arak, Birjand, Karaj, and Shiraz were Darab 14, Safiabad 1, local Ahvaz, and local Isfahan. Also the Karaj location, Fars local cultivar, Khondab local cultivar, and Darab 1 were evaluated as superior. In general, Safiabad 1 and local Khondab were the best genotypes terms of yield and high stability. In contrast, TS-3 and Yellow White genotypes received the most impact from their environment, in addition to low yield. Environment had the least and most impact on Shiraz and Birjand genotypes. Finally,the study area of this experiment were divided into two megaenvironments : Arak, Birjand and Shiraz megaenvironment and Karaj megaenvironment.
