| 摘 要： | 利用微卫星标记技术，分析了山西黎城大青羊、吕梁黑山羊、波尔山羊、南江黄羊（黑）、南江黄羊（黄）五个山羊群体的分子水平上的遗传多样性，结果表明：7个微卫星位点均为高度多态位点。可以用于山羊群体遗传多样性的评估；平均多态信息含量（PIC）达0．8341～0．9026；5个山羊群体平均观察杂合度（0．6258-0．8629）均低于平均期望杂合度（0．8594—0．9115），证明5个山羊种群具有丰富的遗传多样性和广泛的遗传基础，但品种内存在着一定程度的近交，尤其波尔山羊近交较严重。以Nei氏标准遗传距离为基础的UPGMA和N-J聚类结果表明：吕粱黑山羊与南江黄羊（黑）首先聚为一类，而没和黎城大青羊先聚：国内四个山羊群体与国外品种波尔山羊亲缘关系较远。 |

| Abstract: | The genetic diversity of five goat populations was surveyed using 7 microsatellite loci. The five goat populations included Li -cheng blue goat,lvliang black goat,Boer goat, Nanjiang huang goat (blank), Nanjiang huang goat (yellow). The 7 microsatellite loci showed high polymorphism information content value. They can be used for the genetic diversity evaluation in goat breeds.The mean polymorphism information content value was between 0.8341 ~0.9026,which indicated that the 5 populations had abundant genet... |
