So the optimum treating temperature to bivoltine races was from 44～46℃. When unfertilized eggs were treated with hot water for 3～68 minutes, asexual developed eggs could be obtained. But the optimum soaking time range to bivoltine races was 14～ 16 minutes.

针对我国的二化性家蚕现行品种，其无性繁殖诱导温度以44℃~46℃为宜；无性繁殖的处理时间适应范围较广，从3min~68min都可获得一定比例的无性繁殖发育卵，我国的二化性家蚕现行品种，其无性繁殖处理时间以14~16min为宜。

The asexual reproductive eggs and larvae were obtained when 50 commercial and bivoltine races induced by hot water. But the rate of asexual developed eggs varied markedly among these races, the range was 11. 99～88. 88 percent. About one-third races, their rates of asexual developed eggs attained 70～80 percent. The rate of asexual developed eggs about hybrid was higher than its parent.

对我国50个二化性现行品种资源进行无性繁殖发生率调查，结果表明各品种都可经诱导获得一定比例的无性繁殖发育卵和幼虫，但品种间存在较大差异，其发生率范围在11.99~88.88%之间，有1/3品种的无性繁殖发生率达到70~80%，而杂交种的无性繁殖发生率明显超过原种的水平。

Seveteen fine biovotine female lines also had been bred out after 5～10 generations selecting directly to the bivoltine genetic resources, which included 8 Chinese female lines, 8 Japanese female lines and 2 hybrid female lines. These female lines could be reproduced easily by asexual reproductive way, their rate of asexual developed eggs were high with only female generations and economic characters were also stability.

采取直接利用无性繁殖性状较优良的二化性现行品种资源构建雌蚕无性繁殖系的方法，经5~10代的无性繁殖继代选择，初步育成了17个雌蚕无性繁殖品系，其中中系品种8个，日系品种7个，杂交种2个。
