利用性别控制技术实现"农村专养雄蚕,蚕种场多养雌蚕"对提高蚕茧生产的茧丝产量和品质,以及降低雄蚕杂交种的生产成本具有重要意义.将育成的高发生率和高孵化率雌蚕无性克隆系与平衡致死雄蚕杂交,按不完全双列杂交方法组配成31个雄蚕杂交组合,通过3年5期的比较试验,从中筛选出综合经济性状优良的新型雄蚕品种雌35×平28和雌29×平28,并在浙江主蚕区成功试养.新型雄蚕品种与现行雄蚕品种相比,张种产量提高8.53%,解舒丝长增加45 m,鲜茧出丝率提高0.7个百分点.新型雄蚕品种的育成有望进一步降低雄蚕杂交种的生产成本,加速专养雄蚕产业化的进程.

Realizing the technology of rearing only male silkworm in rural area and rearing more female silkworm in eggs-producing station were very important to improve the yield and quality of cocoon silk,and to reduce the productive cost of male silkworm hybrid eggs.Using the method of incomplete diallel crossing,31 combinations of male silkworm were prepared by crossing the female silkworm parthenogenetic clones with high hatching rate and the balanced lethal male silkworm line.Two new male silkworm varieties named Female 35×Ping 28 and Female 29×Ping 28 have been selected out through 5 comparison tests in 3 years,The two new male silkworm varieties have been reared successfully in the main silkworm rearing areas of Zhejiang Province.Compared to the current male silkworm variety,cocoon yield per box of eggs of the new male silkworm varieties increased by 8.53%,length of none-broken filament was 45 m longer,and raw silk rate of fresh cocoonn increased by 0.7 percentage point.The breeding of these new male silkworm varieties makes it expectable to further reduce the production cost of male silkworm hybrid eggs and to accelerate the industrialization process of specially rearing male silkworms.
