摘要
利用杂交育种及系统选择方法,育成了综合经济性状优良的春秋兼用家蚕新品种恒·丰×富玉。经浙江省家蚕新品种实验室鉴定和农村生产试验表明,该品种孵化、眠起、上蔟齐一,茧丝品质优,万蚕产茧量、万蚕茧层量、5龄1日万蚕茧层量分别比对照品种秋丰×白玉提高2.45%、4.91%、5.22%;一粒茧丝长1158m,解舒丝长996m,洁净96.10分,鲜茧出丝率16.12%,均优于对照品种。日系新品种富玉抗BmNPV感染能力较白玉有明显提高。2010年2月该品种通过浙江省农作物品种审定委员会审定。
A new silkworm variety ＂Heng. Feng × Fuyu＂ for spring and autumn rearing with excellent comprehensive economic traits was obtained through cross breeding and pedigree selection. The results of laboratory identification and rural productive test in Zhejiang Province showed that it was uniform in hatching, molting and mounting. Compared with those of the control variety Qiufeng x Baiyu, the cocoon weight per 10 000 larvae, cocoon shell weight per 10 000 larvae, and cocoon shell weight per 10 000 larvae of 1st day of the 5th instar increased by 2.45%, 4.91% and 5.22% respectively. The length of single cocoon filament and none-broken filament was 1 158 m and 996 m respectively, neatness was 96. 10 points, and raw silk rate of fresh cocoon was 16.12%, all of which were also superior over the control variety. More over, anti-BmNPV infection ability of the new variety Fuyu was obviously improved over the variety Baiyu. This new silkworm variety had been approved by the Agricultural Crop Variety Evaluation Commission of Zhejiang Province in February of 2010.
