Abstract: Three sesame entries viz. Gujarat Til-4 (GT-4), Gujarat Til-10 (GT-10) and Patan-64 were treated with 0.5%, 1.0%, 1.5%, 2.0% and 2.5% doses of Ethyl Methane Sulphonate (EMS).In M₁ generation the mutagenic effect of EMS on seed germination with respect to different doses was studied. In M₂ generation analysis of variance, estimation of genotypic coefficient ofvariation (GCV), phenotypic coefficient of variation (PCV), heritability and geneticadvance (GA) were undertaken. Characters like plant height, number of pods per plant, 1000 seed weight and yield per plant exhibited high values of GCV and PCV whereas high heritability coupled with high genetic advance as percent of mean were observed for plant height, number of capsules per plant and yield per plant.
