摘要/Abstract

摘要： 以60只内蒙古绒山羊为研究对象，利用PCR-SSCP技术，选取KAP基因作为候选基因，并利用SPSS软件下的GLM程序分析了KAP基因与产绒量性状、体重性状和绒细度性状的关系。结果表明：产绒量性状上，S1位点的BB基因型和S2位点的BB基因型可以作为标记基因型;在体重性状上，S2位点的BB基因型和S3位点的AA基因型可以作为标记基因型，绒细度性状上，S5位点的BB基因型可以作为标记基因型。在体重和产绒量性状上S2位点的BB基因型，可以作为多性状标记辅助选择的标记位点。

Abstract: Choosing KAP gene as candidate gene, the genetic relationship between KAP gene and economic traits (cashmere yield, weight and cashmere fineness ) of 60 Inner Mongolia cashmere goats were analyzed by PCR-SSCP method, using GLM procedure of SPSS software. The result showed: BB genotype at S1 site and BB genotype at S2 site was favorable marker genotype for cashmere yield trait, BB genotype at S2 site and AA genotype at S3 site was favorable marker genotype for weight trait. BB genotype at S5 site was favorable marker for cashmere fineness trait. BB genotype at S2 site can be the marker genotype of multi-trait marker in assistance selection.
