摘　　要：[Objective] This study aimed to develop a new Bombyx mori variety Shuhuang No.1 and investigate its characteristics.[Method] The new variety was developed through cross breeding and pedigree separation.Its characteristics were identified by laboratory tests and rural promotion practices in Sichuan Province.[Result]The cocoon produced by the new variety Shuhuang No.1 was golden-yellow and radiantly beautiful.Shuhuang No.1 was strong and easy to rear,uniform in development.The male and female ones could be distinguished by their larval color and markings.The cocoon yield per 10 000 the 4th instar larvae reached 20.30 kg; the length of a cocoon filament was about 1 115.0 m,and a non-broken filament was 882.95 mm long,accounting for 79.15％ of the total length.The raw silk ratio of fresh cocoon was 18.39％,and the neatness was 91.25 point.The main economic features of Shuhuang No.1 were better than those of the control.[Conclusion] The new variety had been approved by Sichuan Silkworm Evaluation Commission.It can be promoted in parent silkworm rearing areas Sichuan,Chongqing,Yangtze River basin.[目的]探讨然彩色茧蚕品种蜀黄1号的育成及其特性。[方法]采用杂交育种和系统选择的方法,育成天然彩色茧蚕品种蜀黄1号,并对其进行实验室和农村生产鉴定。[结果]新品种茧丝无需人工染色,色彩天成,金黄、艳丽;新品种具有强健好养、发育整齐、可根据幼虫体色和斑纹区分雌雄的特点;新品种的万蚕产茧量达20.30 kg,一粒茧丝长1 115.0m,解舒丝长882.95 m,解舒率79.15%,鲜茧出丝率18.39%,洁净91.25分。[结论]蜀黄1号已通过四川省家蚕品种审定,适合在四川、重庆等长江流域蚕区饲养。
