摘要
采用杂交育种和系统选择的方法,育成优良家蚕新品种中4、C106、日5,并与引进品种皓月组配成中4.C106×皓月.日5(渝蚕1号)的四元杂交组合。经四川省蚕品种审定的实验室鉴定和农村鉴定,该品种表现出强健、好养、发育整齐、茧丝质优良等特点,全茧量2.45 g、茧层率23.27%、解舒率75.22%,主要经济指标超过对照种。该品种已通过四川省家蚕品种审定,并在生产上试繁推广。
Silkworm races, Zhong4, C106 and Ri5, with excellent quality were bred by the methods of cross breeding and pedigree separation. Three races then were recombined to the introduced race, Haoyue, to develop a multi-way hybrid, ＂Zhong4·C106 × Haoyue·Ri5,＂ designated as Yucan No. 1. The results of laboratory identification and countryside productive test in Sichuan Province showed that it was strong and health, easy to rear, uniform in development, and excellent quality in cocoon and silk. The cocoon weight was 2.45 gram. Cocoon shell rate and reelability were 23.27% and 75.22%, respectively. The main economic indexes of Yucan No. 1 were higher than those of the controls. Thus, Yucan No. 1 had been approved by Silkworm Variety Evaluation Commission of Sichuan Province and started to put into practice.
