The present investigation was undertaken to assess the genotype x environment interaction in sesame by evaluating fourty five genotypes in four different environments created by sowing at two locations (Anand and Vaso) in two different seasons (summer and Kharif) of the year 2019. Pooled analysis of variance across four environments revealed the significant difference among tested genotypes. Variances due to environments were highly significant for all the characters suggested that environments were effective in influencing the performance of genotypes. Mean squares due to G  E interaction were significant for branches per plant, capsules per plant, seeds per capsule, seed yield per plant and oil content revealed that genotypes reacted differentially to different environmental conditions. Both linear and non-linear components were important for genotypic and environmental interactions. The genotype Rama showed desirable mean value of seed yield and average responsive to all kind of environments. Genotypes AT-334, GT-2, PKVNT-11, AKT-101 and Tillottama denoted high mean values of seed yield and high responsive to favourable environments. While, genotypes AT-288, AT-314, AT-390, GT-1, GT-5, GT-10 and TC-66 had high mean values of seed yield and performed well in poor environmental conditions signifying that the stable genotypes can be directly used for different suitable environmental conditions.
