Abstract: In the present study, seed kernels and scions of mango polyembryonic cvs. Peach and Bappakai were treated with different doses (10, 20, 30, 40, 50, 60, and 70 Gy) of gamma irradiation and compared with control. Results suggest that there was gradual decrease in germination percentage of seed kernels and graft success rate with an increase in the dose of gamma irradiation. There was a complete inhibition of germination of seed kernels and success of grafting was observed in the treatments having more than 50 Gy dose. Based on the probit analysis, it was observed that LD50 of gamma rays for the seed kernels of Peach and Bappakai were 27.54 Gy and 23.44 Gy, respectively. However, LD50 of gamma rays for scions of Peach and Bappakai were 19.95 Gy and 21.37, respectively.
