摘　　要：2021年秋季,安康市蚕桑产业发展中心对苏州大学提供的桑蚕新杂交组合JR×HR进行了桑叶育与人工饲料育实验室对比试验。结果显示:与对照种菁松×皓月相比,试验种结茧率高,茧层率低,万头蚕收茧量低,解舒率低,茧丝长短,解舒光折大;试验种桑叶育龄期经过短,虫蛹统一生命率低;试验种人工饲料育龄期经过长,死笼率低,虫蛹统一生命率高。In the autumn of 2021,Ankang Sericultural Development Center conducted a laboratory comparison test on breeding with mulberry leaves and artificial diet of a new silkworm hybrid variety JR×HR provided by Suzhou University.Results show that compared with the control variety Jingsong×Haoyue,the test variety has high cocoon rate but low cocoon shell rate,cocoon quantity of ten thousand silkworms,reelability and short silk filament,its reelability refraction is big.Additionally,the new variety has short production duration and low uniform life rate for pupa when it is fed with mulberry leaves,but when it is fed artificial diet,the production duration is long,the death rate is low and the uniform life rate for pupa is high.
