贵蚕13号在贵州不同海拔地区的适应性

Adaptability of Guican 13 (a New Silkworm Hybrid Combination) in Silkworm Rearing Areas with Different Elevation in Guizhou

贵蚕13号(暂定名)是贵州省农业科学院蚕业研究所选育的一个新组合,适应性广泛,在区试中表现突出,为进一步掌握该品种在贵州不同海拔蚕区的应用效果,于2016—2017年春、夏季分别在威宁县(海拔1 700m)、黄平县(640m)和荔波县(425m)进行饲养试验。结果表明:贵蚕13号在高、中、低海拔蚕区适应性广,发育整齐、少病,产茧量较高、茧质好。与对照品种两广二号相比,贵蚕13号死笼率低、张种产茧、产值增加明显,贵蚕13号适合在贵州各主要蚕区用于春夏季饲养。

Guican 13 with a wide adaptability is a new silkworm hybrid combination bred by Sericultural Institute,Guizhou Academy of Agricultural Sciences.The rearing experiment of Guican 13 was conducted in Weining County with an elevation of 1 700 m,Huangping County with an elevation of 640 mand Libo County with an elevation of 425 min Spring and Summer Seasons during 2016—2017 to further master the application effect of Guican 13 in silkworm rearing areas with different elevation in Guizhou.Results：Guican 13 performances the advantages of wide adaptability,development consistency,less disease,high cocoon weight and good cocoon quality in three silkworm rearing areas with different elevation.Guican 13 with lower rate of dead cocoons,high cocoon yield per case of eggs and output value compared with Liangguang 2（CK）is suitably reared in main silkworm rearing areas in Spring and Summer seasons in Guizhou.
