Abstract
The studies during M1 indicated that the reduction in survival percentage was higher in 250 Gy dose in all the varieties treated indicating that the reduction in survival percentage was dose dependent. Gamma irradiation at 250 Gy in R-2001-2, R-8808 and TAG-24 recorded highest mutation frequency indicating that the mutational frequency is depends on the dosage of gamma rays. In general, the frequency of variants for pod features in M2 was more in R-2001-2 (0.36%) than in R-8808 (0.32%) and TAG-24 (0.29%) indicating that R-2001-2 is more sensitive to mutagenic treatments. In all the three genotypes, a dose of 250 Gy gamma irradiation was accompanied by an increase in the number of variants for pod features compared to lower dose at 150 Gy.
