摘　　要：根据GenBank在绵羊1、4、6号染色体上选取13个微卫星基因座,对被测中国美利奴绵羊群体部分毛用性状的表型数据资料按基因型分组进行方差分析和多重比较。结果表明,标记羊毛细度的BM6506、OARDB6基因座不同基因型间差异达到了极显著水平(P<0.01),标记羊毛细度的BM2263、BMS835I、LSTS044、OARAE57、BMS178基因座不同基因型间差异达到了显著水平(P<0.05),可对羊毛细度进行标记;标记羊毛长度的BMS835和BM6438基因座不同基因型间差异达到了极显著水平(P<0.01),标记羊毛长度的BMS2263、OARDB6、OARCP26、BM143基因座不同基因型间差异达到了显著水平(P<0.05),这些基因座可对羊毛长度进行标记。13 micro satellite loci were selected in sheep 1,4 and 6 chromosomes from Genebank, according to genotype group, the wools phenotypes data of the tested sheep population were analyzed by ANOVA and multiple comparison. The result indicated that, wool fiber diameter of different genotype marked by BM6506 and OARDB6 has got the significanty different level（ P 〈 0.01 ）, and BM2263, BMS835, ILSTS044, OARAE57, BMS1788 have got the difference level（ P 〈 0.05） ,so those micro-satellite loci could mark wool fiber diameter; wool natural length of different genotype marked by BMS835 and BM6438 have got the significanly different level（ P 〈 O. 01 ）, and marked by BMS2263, OARDB6, OARCP26, BM143 have got the different level（ P 〈 0.05）, so those micro-satellite could mark wool natural length.
