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.

Abstract


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.
