摘　　要：针对蚕种和蚕茧生产省力化、规模化的发展需求,选育出综合经济性状优良的斑纹限性抗血液型脓病家蚕新品种农科5号。浙江省家蚕新品种实验室鉴定结果显示,农科5号的4龄起蚕虫蛹率与对照(秋丰×白玉)相仿,万蚕产茧量、万蚕茧层量分别比对照提高11.34%、15.12%;洁净94.98分,出丝率比对照高1.17百分点。浙江省农村生产试验结果显示,农科5号的张种产茧量48.2 kg,比对照提高9.54%;健蛹率96.56%,比对照提高2.92百分点。抗血液型脓病检测结果表明农科5号的抗病指标为对照的161倍。新品种于2021年5月通过浙江省主要农作物品种审定委员会审定,适合在浙江全省蚕区春期及条件较好的区域秋期饲养。In response to the need for labor-saving and large-scale development of silkworm egg and cocoon production,a new sex-limited marking quaternary silkworm variety with resistance to Bombyx mori nucleopolyhedrosis was bred.According to the laboratory new silkworm variety identification results in Zhejiang Province,the larvae-pupa survival rate of Nongke 5 was almost the same as the control variety QiufengxBaiyu,while its cocoon weight and cocoon shell weight per 10000 larvae increased by 11.34%and 15.12%,respectively.Its neatness was 94.98 points and its raw silk rate was 1.17 percentage points higher than that of the control variety.In the rural production test of Zhejiang Province,the cocoon yield per box of eggs of Nongke 5 was 48.2 kg,9.54%higher than that of the control variety,and the healthy pupae rate of Nongke 5 was 96.56%,2.92 percentage points higher than that of the control variety.Detection results showed that the index of resistance to nucleopolyhedrosis of Nongke 5 was 161 times that of the control variety.Nongke 5 was approved by the Crop Variety Evaluation Committee of Zhejiang Province in May 2021 and suggested for rearing in spring in Zhejiang Province in autumn in some areas with good condition.
