摘要: 试验分析了7个微卫星基因座位OarAE101、OarJMP8、BM143、BM6506、BM1824、BM6438、ILSTS004在辽宁绒山羊4个家系中的遗传多态性。结果表明,7个微卫星标记中仅有4个微卫星位点(OarAE101、OarJMP8、BM143、BM6506)表现出了多态性。OarAE101位点多态信息含量最高,为0.727;BM143位点多态信息含量最低,为0.526。在所标记群体中平均有效等位基因数为3.249个;平均多态信息含量为0.635;遗传杂合度均值为0.638。说明辽宁绒山羊品种内的遗传变异处于一个较高的水平,遗传多样性丰富,选择潜力很大。

Abstract: The genetic polymorphisms of 7 microsatellite loci (OarAE101, OarJMP8, BM143, BM6506, BM1824, BM6438, ILSTS004) in four families of Liaoning cashmere goat.The results showed that there were 4 microsatellite loci (OarAE101, OarJMP8, BM143, BM6506) showed polymorphism in 7 microsatellit loci. Polymorphic information contents of OarAE101 was the highest, PIC was 0.727, and that of BM143 was the lowest, PIC was 0.526 at 7 microsatellite loci in Liaoning cashmere goat. The average effective numberofallele, the average PIC values and the average genetic heterozygosity were 3.249,0.635 and 0.638, respectively. It showed that variety the hereditary change was in a high level of Liaoning cashmere goat, the heredity multiplicity was very rich, the choice potential was very big.

Key words: Liaoning cashmere goat; microsatellite; genetic diversity
