摘　　要：茧丝纤度是评价茧丝品质的重要指标,属于典型的数量遗传性状,对其遗传基础的研究具有重要的科学意义和经济价值。本文从家蚕的茧丝纤度性状差异出发,综述了茧丝纤度的遗传分析、不同纤度品种选育、与其他性状的相关性以及控制基因的解析等方面的研究进展。总体上,茧丝纤度遗传基础研究十分欠缺,尤其需加强从分子水平研究其遗传信息。Cocoon silk fineness is an important index of cocoon silk quality and belongs to typical quantitative genetic traits,and the study of its genetic basis has tremendous scientific significance and economic value.Starting from the differences of fineness traits,this paper reviews the progress of researches on the genetic analysis of cocoon silk fineness,the selection and breeding of different fineness varieties,the correlation with other traits and the analysis of control genes.In general,basic researches on cocoon fineness genetics are still very lacking,especially those on the molecular level.
