摘　　要：家蚕品种选育的目标经济性状多属于典型的数量性状,其遗传基础研究是家蚕育种发展的重要基础。由于茧丝产量与品质直接关系到养蚕业和丝绸工业的效益,故近百年来茧质相关性状是家蚕数量遗传研究的重点。21世纪以来,随着基因组学的发展和功能基因研究体系的日臻完善,家蚕数量性状遗传研究进入一个新的阶段。近年来,家蚕茧丝产量和茧丝纤度主效基因的鉴定先后获突破,家蚕泛基因组计划研究成果为该领域的发展奠定了更加坚实的基础。本文着重对家蚕茧丝数量性状的分子遗传基础研究最新进展进行综述,以期为针对家蚕茧丝性状的分子改良提供参考。The breeding selective traits of silkworm are typical quantitative traits,and research on their genetic basis is an important foundation for the progress of silkworm breeding.Due to the significant value of silk in sericulture,traits related to silk have long been a focus of quantitative genetic research on silkworms,with a research history nearly 100 years.Since the beginning of the 2lst century,with the advancement of genomics and the continuous improvement of functional gene validation systems,the genetic research on quantitative traits in silkworms has entered a new stage.In recent years,breakthroughs have been made in identifying major genes related to silk yield and fiber fineness in silkworms,and the silkworm pan-genome have laid a more solid foundation for this field.Here we review the progress in the molecular genetic basis of quantitative traits related to silk,aiming to provide references for the molecular improvement of silkworm silk traits.
