摘　　要：[Objective] To study the cocoon traits of wild silkworm descendants. [Method] In the selective breeding of domesticated raising wild silkworm and wild silkworm descendants, investigation on the traits of the built cocoons was carried out. [Result] The pointed traits of cocoons displayed obviously in the wild silkworm descendants, its pointed parts were consistent with the rear part of silkworm chrysalis, and the female silkworm has slight difference, indicating the silkworm co- coon pointed trait was hereditary. [Conclusion] This study provided references for the study of silkworm cocoon traits of wild silkworm descendant and guides the selective breeding of silkworm variety.[目的]研究野蚕后代的蚕茧性状。[方法]在驯化饲养野蚕及野蚕后代的选育中,对其所结蚕茧的性状进行了调查。[结果]蚕茧尖头性状在野蚕后代中表现明显,其尖头部位与蚕蛹尾部明显一致,雌蚕略有不同,表明蚕茧尖头性状存在遗传。[结论]该研究为野蚕后代的蚕茧性状研究提供了一定参考依据,对蚕品种选育具有指导意义。
