The present investigation was carried out to study the extent of variability existed in the sesamum varieties namely TMV 4, TMV 7, VRI 2, Thilak and TNY Local after induction of mutation through chemical mutagens namely EMS. The results of M1 generation revealed that there was a shift in the mean for the characters Viz., Days to first flowering, Plant height, Number of branches per plant, Number of capsules per plant, Length of capsule, Number of seeds per capsule, Seed yield per plant, 1000-seed weight and Oil content towards positive /negative directions. In M2, chlorophyll mutants namely, albina, xantha, chlorine, viridis and few viable mutants like giant plant, bushy plant, unifolitat leaf, narrow leaf, crinkled leaf, short capsule, black seeded, sterile plant and pigmented mutants were recorded figures 1 and 2. A significant increase in number of plant height, number of capsule per plant, number of seed per capsule and seed yield per plant was noticed in M2 generation. The PCV and GCV showed significantly higher values in yield component characters such as number of capsule per plant, number of seed per capsule, Length of capsule and seed yield per plant in M2 generation. The yield attributing traits like number of capsule per plant, number of seed per capsule, Length of capsule and 1000-seed weight recorded high heritability coupled with high genetic advance as per cent of mean in M2 generation.
