摘要
2018年春,河南省蚕业科学研究院对北方蚕区3对桑蚕新品种进行了实验室鉴定试验。试验结果表明:鲁87×鲁88万头产茧量24.13kg、万头茧层量6.285kg、万头产丝量4.938kg,分别比对照品种高出8.12%、15.43%、15.21%;永中3号4龄起蚕虫蛹率比对照品种高3.53个百分点;苏婴×熙阳的茧丝纤度2.427dtex,纤度较细。
In the spring of 2018,Henan Sericulture Institute conducted a laboratory identification experiment on three new silkworm varieties from northern silkworm rearing area.Results showed that the cocoon crop per 10 000 silkworms of Lu 87×LU 88 was 24.13 kg,the cocoon shell weight per 10 000 silkworms was 6.285 kg,and the silk yield per 10 000 silkworms were 4.938 kg,which were 8.12%,15.43%and 15.21%higher than that of the control,respectively;Yongzhong No.3 had a 3.53 percent higher larva-pupa rate at 4th instar than that of the control;the size of cocoon filament of Suying×Xiyang was 2.427 dtex,with a rather fine size.
