2023年春季北方蚕区家蚕新品种实验室鉴定(山西点)报告

Report on Laboratory Identification of New Silkworm Varieties in Northern Silkworm Raising Area(Shanxi Site)in Spring of 2023

2023年春,山西省蚕业科学研究院对天然彩色茧家蚕新杂交组合“313×410”进行了实验室鉴定。结果表明:该品种全茧量、结茧率、虫蛹统一生命率、万蚕收茧量、万蚕茧层量、上车茧率、茧丝长、解舒丝长、茧丝纤度均略高于菁松×皓月,茧层量与菁松×皓月相当,万米吊糙低于菁松×皓月。综合分析认为:家蚕新杂交组合“313×410”抗逆性较强,好饲养,茧形大、产量高,茧丝质量优。

In spring of 2023,the Shanxi Sericulture Research Institute conducted a laboratory identification on the new hybrid combination of natural colored cocoon silkworms"313×410".The results showed that its total cocoon yield,cocooning rate,uniformity of cocooning pupae,cocoon yield per 10,000 silkworms,cocoon shell weight per 10,000 silkworms,cocoon shell percentage,cocoon filament length,length of non-broken filament,and size of cocoon filament were slightly higher than those of the Jing Song×Hao Yue variety.Its cocoon shell weight was equivalent to that of Jing Song×Hao Yue,while the raw silk roughness per 10,000 meters was lower than that of Jing Song×Hao Yue.A comprehensive analysis suggests that the new silkworm hybrid combination"313×410"exhibits strong resistance,which is easy to rear,produces large cocoons with high yields,and has excellent silk quality.
