Ripe, fresh seeds of six high-yielding cultivars were irradiated with 1-4 Krads of gamma rays and seed germination and seedling abnormalities were studied. Cultivars showed differential radiosensitivity with regard to germination and seedling chlorophyll abnormalities. The reduction in germination was found to be almost linear and the LD50 (in terms of germination) was between 2.5 to 3.5 Kr in most of the cases
