摘　　要：平衡致死系“平30”迟眠蚕,虽然生长发育较缓慢,龄期经过有所延长,但各龄迟眠蚕的饲养成绩与对照区差异不大,因此在“平30”饲育过程中应慎重淘汰迟眠蚕,避免将发育缓慢的雄性健康个体淘汰,以致种茧雌雄比例失调,从而影响蚕种生产。Late-molted silkworms of the variety“Ping 30”(a balanced lethal system)grow and develop slowly with extended in star periods buthave comparable performance with the control group.Therefore,the elimination of late molted silkworms should be careful during breeding“Ping 30”,to avoid eliminating those healthy male individuals,which affected silkworm production due to the disproportionation of male to female ratio.
