摘　　要：采用杂交育种的方法,育成了春用家蚕新品种新.莹×玉.泉。经四川省、江苏省实验室品比鉴定和农村试养的成绩表明,新品种的万蚕产茧量、万蚕茧层量、茧丝长和鲜茧出丝率均超过对照品种菁松×皓月,解舒率、洁净、纤度等主要经济性状与对照品种相似。新品种与对照品种相比更容易饲养和繁殖。2007年1月通过四川省家蚕品种审定,适合于长江流域及其以北蚕区春期饲养。By using the method of cross breeding, a new multi-way hybrid silkworm variety, ＂Xin·Ying × Yu·Quan＂, was bred for spring rearing. The results of laboratory identification and countryside rearing test-in Sichuan and Jiangsu Provinces showed that cocoon crop per 10 000 larvae, cocoon shell weight per 10 000 larvae, raw silk rate of fresh cocoon, and length of cocoon filament were higher than those of the control, ＂Jingsong × Haoyue＂. Meanwhile, the main economic characters （such as reelability, neatness, size, etc. ） of ＂Xin·Ying × Yu·Quan＂ were similar to the control. In addition, it was easier to rear and has higher reproductive ability than the control. Thus, ＂Xin·Ying × Yu·Quan＂ had been approved by Silkworm Variety Evaluation Commission of Sichuan Province in Jan, 2007. It was suitable to rear in the valley of the Yangtze River and north area in China.
