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。

Particularly,the CP content of H.compressa from Caoba is 3.0% higher than that of H.compressa cv.Chonggao.Therefore,there is a promising for H.compressa from Caoba to offer an alternative to be a new variety.By the clustering analysis,all native accessions are classified into four different types,which is helpful to choose and utilize further.
