Effect of different gamma sterilizing doses on the fertility and progeny production of pulse beetle (callosobruchus maculatus)

The effect of gamma radiation doses on fertility and progeny production of c. maculatus was studied and sexed adults were ex-posed to various radiation doses. After irradiation, six pairs replicates were selected from each radiation dose and released into 5g mungbeans. The results showed that fertility was improved upto 41% in females from male irradiated and 86% in females from female irradiated. The improvement and fertility was upto 52% and 80% at 2.5 Krad when the irradiated parents were male and female respectively. The genetic damage in subsequent generation was higher in progney process of irradiated parent male. (A.B.)
