The induced mutation through different gamma irradiation frequencies viz. 100, 200, 300, 400 and 500 Gy in some agronomic traits of five mungbean cultivars was studied at Research Area of Faculty of Agriculture, Gomal University, D. I Khan for consecutive three years. The results of analysis show that a wide range of variability exists in all the characters except plant height. The genotypic effect on days to flowering, days to maturity, plant height. Number of branches, Number of pods and Number of clusters ranged from 43.82 to 44.96 days, 87.60 to 91.75 days, 42.16 to 51.61 cm, 1.83 to 2.07. 16.97 to 21.46 and 4.44 to 5.56, respectively. Similarly, mutagenic effects on days to 50% flowering days for maturity, plant height, number of branches, number of pods and number of ranged from 44.05 to 45.62 days, 88.62 to 91.83 days, 47.07 to 43.43 cm. 1.62 to 2.00, 17 to 22.30 and 4.53 to 5.50 respectively. The genotype X dose interaction was highly significant for days to 50% flowering, maturity, number of branches and clusters and non-significant for plant height and number of pods.
