INVESTIGATION ON GAMMA RAY INDUCED MUTATIONS IN MUNGBEAN [Vigna radiata]

Dry seeds (10% sprinkled state content) of mung bean [Vigna radiate L. wilczek] were treated with 100, 200, 300, 400 and 500 Gy ˠ-irradiation to study the agronomic properties of two mung bean cultivars. A wide level of progress exists in the aggregate of the characters. The Mutagenic repercussions for germination, continuation, pollen fertility, number of branches, changes from 35.65 (500 Gy) to 57.71 (100Gy), 55.50 (500 Gy) to 75.43 (100 Gy), 65.23(500 Gy) to 87.71(100 Gy), 59.32 (500Gy) to 83.20 (100Gy), 38.23 (100Gy) to 45.79 (400Gy), 40.55 (500 Gy) to 50.14 (300 Gy), 49.05 (500 Gy) to 76.47 (100 Gy), 47.36 (500 Gy) to 74.00 (100 Gy), 5.85 (500 Gy) to 7.34 (100 Gy) and 5.73 (500 Gy) to 7.56 (100 Gy), 4.91 (500 Gy) to 6.81 (100 Gy), 4.96 (500 Gy) to 6.98 (100 Gy) for VBN3 and Co7 mix emblematically.
