强健性多丝量蚕品种“野三元”的育成

Breeding of a New Silkworm Variety "Yesanyuan" with Healthiness and Hypersilk

[目的]培养强健性多丝量蚕品种。[方法]将抗逆性强的野桑蚕与多丝量家蚕品种远缘复合杂交,培育出的优质野桑蚕基础素材野A和野B,并将其与日系蚕品种进行杂交组配,筛选强健性多丝量蚕品种。[结果]经江苏省家蚕新品种实验室鉴定和农村生产试验表明,具有食性优、抗逆性强、产量高、茧丝质优良、繁育性能优的特点,并定名为"野三元"。2008年通过江苏省家蚕品种审定,适宜长江流域春、秋季及北方蚕区全年饲养。[结论]该研究将有助于蚕丝产业的进一步发展。

[Objective]The study aimed to breed silkworm variety with hypersilk. [Method]Eminent mulberry wild silkworm basic materials Ye A and Ye B were, bred by distant complex crossing of wild mulberry silkworm with strong stress resistance and hypersilkgeneous silkworm, then hybridized with Japanese silkworm strain, the new silkworm variety ＂Yesanyuan＂ with healthiness and hypersilkgene was bred. [ Resuh]The results of laboratory identification and rural productive test in Jiangsu Province show that it has excellent feeding habit, strong stress resistance, high yield, excellent silk quality and excellent fecundity. The new silkworm variety ＂Yesanyuan＂ had been apprm,ed by Silkworm Variety Evaluation Commission of Jiangsu Province in 2008, it is suitable to rear in Yangtze River catchment for Spring and Autumn, North sericultural area for all-year. [Conclusion]This result is helpful for the development of silk industry. Key words
