Evaluation of effect of gamma rays on sesame genotype TTVS 51 and TTVS 19 in M1 generation

Sesame (Sesamum indicum L. syn. S. orientale Linn.) genotypes TTVS 51 and TTVS 19 was exposed to variable doses of gamma rays to study their consequence on several characters like plant height, number of branches, days to 50% flowering, Number of capsule per plant, thousand seed weight and single plant yield. In M1 generation the results disclosed that there was more reduction at higher doses compared to lower doses for all the characters. The findings were obtained in this study evidently indicate the difference doses of gamma rays can be successfully utilized to create variability for various quantitative traits of this crop.
