摘　　要：以家鹌鹑为参照,并搜集国内外6个家鹌鹑和野生鹌鹑群体的相同资料,检测野生日本鸣鹑和野生普通鹌鹑群体中编码脏器、肌肉酶型的10个结构基因座上的基因频率分布,计算各座位杂合度、群体平均杂合度及其差异性检验和遗传分化系数等相关指标,用模糊聚类多元分析方法对我国境内分布的2种野生鹌鹑生物多样性和遗传分化程度进行分析。结果表明:相对日本列岛的野生鹌鹑而言,我国野生鹌鹑群体遗传多样性更为丰富,野生日本鸣鹑和野生普通鹌鹑的群体平均杂合度分别为0.388和0.298,与家鹌鹑群体多样性差异和遗传分化程度较小,差异不显著。多元分析也表明我国野生鹌鹑与各种家鹌鹑群体有较近的亲缘关系。Genetic diversity of two wild quail species distributed in China, wild Japanese quail and wild Common quail, were studied with gene frequency of 10 loci in viscera and muscle in 9 quail populations at home and abroad, thereinto, the data of 6 quail populations were cited from other researchers. According to the comparison of corresponding genetic index of quail populations, such as heterozygosity of each locus, mean heterozygosity, genetic differentiation coefficients and multivariate analysis method, the results were shown as follows, in contrast to wild quail populations across Japanese Islands, wild quail in China possessed of rich biological diversity, and mean heterozygosity of wild Japanese quail and wild common quail were 0. 388 and 0. 298, respectively; Moreover, the two wild quail species had no significant difference in genetic diversity and differentiation with kinds of domestic quail populations. In addition, the two wild quail was also closer to domestic quail populations in phylogenetic relationsbip than wild quail across Japanese Islands based on fuzzy cluster.
