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。

Of the 36 tussah silkworm varieties, the Nei's genetic diversity index was 0.3243±0.1515, and Shannon information index was 0.4871±0.1975, suggesting that bivoltine tussah silkworm varieties are still rich in genetic diversity even having been conserved in the same place for quite long time. Nei's genetic identity of the 36 varieties ranged from 0.4959 to 0.8347, 96.59% of which was above 0.6, revealing large similarity between different varieties. A clustering analysis showed that these varieties formed two separate clades, one of which included varieties bred by the institute and the other included imported varieties from other provinces or countries.

供试品种资源的Nei氏遗传多样性指数为0.3243±0.1515，Shannon信息指数为0.4871±0.1975，表明长期同地保存的二化性柞蚕品种资源同样具有丰富的遗传多样性；供试品种的Nei氏遗传一致性范围在0.4959~0.8374之间，达0.6以上的占96.59%，表明多数品种资源的相似程度较高。36份品种资源分别以辽宁省蚕业科学研究所育成种为主和以国内外引进种为主聚为两大类群。

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。
