Seeds of sesame (Sesamum indicum L), genotypeTMV3 were treated with various concentrations of EMS and Colchicine like 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4, 1.6, 1.8 and 2.0 % and the LD50 values observed at 1.0 % of EMS and 0.6 % of Colchicine. Based on their LD50 values appreciable concentrations only selected for further study and their effects on various morphological characters such as plant height per plant, number of branches per plant, number of leaves per plant, days to first flowering, number of capsules per plant, number of seeds per capsule and seed yield per plant (g) were measured quantitatively and the results showed that all the characters were consequently or significantly reduced when compared to control and also EMS showed more effective than colchicine.
