摘　　要：为了解不同桑树品种叶片对洞庭原蚕和碧波原蚕的生命力、种茧质量及F1卵质的影响,试验采用云桑1号、湖桑197、湘7920桑树品种的叶片分别饲养洞庭原蚕和碧波原蚕。结果表明,不同桑树品种叶片对饲养的洞庭原蚕、碧波原蚕幼虫1～4龄经过影响不明显,但对洞庭原蚕和碧波原蚕的5龄经过和全龄经过有明显的影响,原蚕全龄经过均以湘7920的饲育区最长(洞庭原蚕605 h、碧波原蚕604 h)。从原蚕个体重量、生命力各项指标、种茧质量和F1卵质综合成绩来看,在贵州省春季环境条件下,适宜洞庭原蚕和碧波原蚕饲养的桑树品种依次为云桑1号、湖桑197、湘7920。The leaves of 3 Mulberry （Morus alba） varieties, Yunsang No.l, Husang197 and Xiang 7920, were used to feed Dongting original silkworm and Bibo original silkworm to study their effects on the vitality, seed cocoon quality and F1 egg quality. The results showed that the effect of mulberry varieties leaves on the 1-4 instar larva of Dongting original silkworm and Bibo original silkworm was not significant, while on 5 instar larva and whole instar was obvious. Whole instar length of original silkworm fed by Xiang 7920 was the longest （Dongting original silkworm, 605 h; Bibo original silkworm, 604 h）. Ac-cording to the indexes of individual weight, vitality of silkworm, seed cocoon quality and Fx egg quality, mulberry varieties suitable for cultivation of Dongting original silkworm and Bibo original silkworm in Spring in Guizhou province ranked as Yunsang No.l, Husang197, Xiang 7920.
