Induced Mutation Studies in Some Mungbean (Vigna radiata L.)wilczek Cultivars

Muhammad Yaqoob and Abdur Rashid
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 for consecutive three years. A wide range of variability exist 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 clusters ranged from 44.05 to 45.62 days, 88.62 to 91.83 days, 47.07 to 48.43 cm, 1.62 to 2.00, 17 to 22.30 and 4.53 to 5.50 respectively. The genotype X dose interaction were highly significant for days to 50% flowering, maturity, number of branches and clusters and non-significant for plant height and number of pods
