摘　　要：云夏3×云夏4是一对含有多化性血统的二化性夏秋用种。2021年晚秋蚕期云南省农业科学院蚕桑蜜蜂研究所进行了云夏3×云夏4原原种饲育对比试验。中日系原原种品比试验的结果,云夏3A、云夏4A全龄发育经过时间较短,云夏3B的全茧量较小、茧层率较高,云夏3A、3B的克蚁收茧量明显低于菁松A、B,云夏4A的全茧量、茧层率、虫蛹统一生命率以及克蚁收茧量明显高于皓月A、B。Yunxia3×Yunxia4 is a pair of dualistic summer and autumn species with multiple sexual lineages.In the late autumn of 2021,the Research Institute of Sericulture and Bees of Yunnan Academy of Agriculture conducted a comparative test on the breeder seed of original species for Yunxia3×Yunxia4.The results of the comparison test of Chinese and Japanese original varieties showed that the full-age development of Yunxia 3a and Yunxia 4A took a short time,the total cocoon amount of Yunxia 3B was small and the cocoon layer rate was high,the cocoon collection amount of Yunxia 3a and 3b was significantly lower than that of Jingsong A and B,and the total cocoon amount,cocoon layer rate,unified pupa life rate and cocoon collection amount of Yunxia 4A were significantly higher than that of Haoyue A and B.
