| Abstract: | Four commercial silkworm varieties, Fengyi, Xinhang, Baiyun and 54A, were rejuvenated and their F1 hybrids were compared with that of the present commercial lines. Results showed that there were same in the performance of fifth instar duration and larval duration, and similar in survival rate. However,most of the productivity traits were improved. Therefore, the rejuvenated lines were improved not only in its pure lines, but also in their F1 hybrid, and suggested to be used for commercial production. |
