摘　　要：利用微卫星标记技术分析了中国10个地方猪群体的亲缘关系。结果表明:不同的聚类方法导致的结果不同,根据Nei’s距离所得的NJ聚类结果与实际情况较为符合,它将10个地方猪群体分为3个类群:五指山小型猪、滇南小耳猪、贵州小型香猪及其近交系4个小型猪为一类群:沂蒙黑猪、汉中黑猪与荣昌猪为一个类群;二花脸猪、金华猪与巴马香猪近交系为一个类群。Genetic relationship of 10 indigenous pig populations was analyzed by 10 microsatellite markers. Results showed that different phylogenetic methods led to different results. The NJ phylogenetic tree from Nei＇s genetic distance was consistent with the facts. The 10 pig populations were divided into 3 clusters. The first cluster was Guizhou miniature pig and its inbreeding lines, Diannan xiaoer and Wuzhishan miniature pig, the second Yimeng black pig and Rongchang pig, and the third Erhualian. Jinhua and Bama miniature pig.
