The mtDNA from 14 Raccoon dogs of 7 geographical populations was analyzed with 8 restriction endonucleases, and the restriction map was constructed. Furthermore, UPG molecular phylogenetic trees of the mtDNA were constructed based on the genetic distances. Our results indicated that the differentiation was obvious within geographical populations of the subspecies N. p. procyonoides, and that the event of divergence in Chinese Raccoon dog first occurred between the southern and northern populations, and then, between the western and the eastern populations. We proposed that both of the Huabei and Shanxi populations which had not been identified could be classified into two independent subspecies respectively.
用8种限制性内切酶分析了7个地理种群的14只貉的线粒体DNA（mtDNA），构建了限制性图谱。此外，基于遗传距离构建了mtDNA的UPG分子系统发育树。我们的结果表明，亚种N. p. procyonoides的地理种群内分化明显，中国貉的分化事件首先发生在南方和北方种群之间，然后发生在西部和东部种群之间。我们建议，尚未确定的华北种群和山西种群可分别归为两个独立的亚种。
