摘要: 以120只内蒙古白绒山羊为研究对象,利用PCR—SSCP技术,选取编码羊毛纤维组成蛋白基因中KAP1.3和KAP6.1的部分序列作为候选基因,通过对其多态性的研究,探索将该基因作为候选基因来间接选择绒山羊经济性状的可行性。结果表明,应用分析软件中的单因素方差分析中,角蛋白辅助蛋白的多基因家族中的甘氨酸酪氨酸角蛋白辅助蛋白(KAP6.1)中,位点s2与产绒量有显著的相关性(P〈0.05);多重比较发现S2位点的AA基因型和BB基因型与产绒量之间有显著的相关性(P〈0.05);AB基因型和BB基因型的绒细度之间差异显著(P〈0.05)。

Abstract: 120 Inner Mongolia cashmere goats were selected in this study. Parts of the sequences of KAP1.3 and KAP6.1 genes from cashmere fiber protein were selected as the candidate genes by PCR-SSCP techniques. The selection of the economic traits of the candidate genes were evaluated through studying on its Polymorphism. The results showed that there was significant correlation between the site S2 and the cashmere yield trait(P〈0.05) in KAP6.1 in the muhi-gene family of the keratin accessory protein by oneway Anova of the analysis software. The AA and BB genotypes were also significant correlated with cashmere yield trait by multiple comparison (P〈0.05). The AB and BB genotypes had signifieant effects on fine wool quality (P〈0.05).
