Abstract:
The mutagenic effects of different doses of gamma rays (400, 500, 600 and 700 Gy) on sesame (Sesamum indicum L.) genotypes i.e. AKT-64 and N-8 in M₁ generation with aims to evaluate the effects of gamma rays on days to 50% flowering, days to maturity, plant height, number of branches per plant, number of capsules per plant, 1000 seed weight and seed yield per plant. In M₁ generation the results revealed that there was more reduction at higher doses compared to lower doses for all the characters. Mutation breeding offers the possibility of recovering some of the lost but useful variability in sesame, especially improved yield.
