| Abstract: | Objective] This study aimed to breed silkworm varieties with excellent comprehensive characters suitable to be cultivated in both spring and autumn. Method] The reciprocal cross was made between Chinese cultivar 781 and nine Japanese lines, Japanese cultivar 7532 and nine Chinese lines, to breed silkworm varieties with excellent comprehensive characters. Result] The cocooning rate, survival rate of pupae, cocoon yield per 10 000 silkworms, cocoon shell weight per 10 000 silkworms, whole cocoon weight, cocoon shell weight and cocoon shell rate among different silkworm combinations showed extremely significant difference. Conclusion] The research laid the foundation for analyzing the combining ability of silkworm cross combinations and breeding ideal combinations. |
