Mutagenic Effectiveness and Efficiency of Gamma Rays in Blackgram (Vigna mungo L.) Hepper) in M2 Generation
Subscribe/Renew Journal
The mutagenic effectiveness and efficiency of gamma rays viz., 40, 50, 60, 70 and 80 kR in three varieties of urd bean cultivars namely ADT 3, ADT 5 and APK 1 were studied. The effectiveness of gamma ray shows a consistent relationship of lower doses of gamma ray was found more effective in M1 plant and M2 seedling basis. The high effectiveness was recorded in ADT 5 at 40 kR followed by 50 kR in ADT 3 and APK 1 at 50 kR on M1 plant basis. In M2 seedling basis the high effectiveness was recorded in ADT 3 at 50 kR followed by ADT 5 at 40 kR and APK 1 at 60 kR. The mutagenic efficiency directly proportional with the increase in the dose among all the varieties studied.
