Abstract:

Mutagenic effectiveness and efficiency of gamma rays were studied in three genotypes of Indian mustard (two local cultivars and one improved variety). From the present study, it was suggested that the LD50 ranging from 1000 Gy (pollen sterility) to 1200 Gy or above (survival reduction) may be used for gamma ray treatment in Indian mustard. Five types of chlorophyll mutants were observed in the order of Albina> Chlorina=Viridis> Xantha=Alboviridis. The highest mutation frequency was recorded from 1000 Gy gamma ray treatment which was followed by 1200 Gy. Mutagenic effectiveness was found to be highest at 1000 Gy gamma ray treatment. The mutagenic efficiency, in terms of lethality, was found to be the highest at 800 Gy. However, mutagenic efficiency for both injury and sterility was found to be highest at 1000 Gy.
