摘　　要：线粒体DNA中的细胞色素C氧化酶亚基Ⅰ基因,即COⅠ是DNA条形编码的主要基因,是一个很好的物种鉴定工具,目前广泛应用于鸟类系统发育研究。通过测定花尾榛鸡和黑琴鸡COⅠ基因的序列,并结合GenBank中松鸡科13种鸟类的同源序列,对松鸡科鸟类进行了序列变异和系统发育分析。结果显示,松鸡科物种的种间变异大于种内变异。序列分歧和系统分析结果支持花尾榛鸡Tetrastes bonasia归于松鸡科Tetraonidae榛鸡属Tetrastes。黑琴鸡Lyrurus tetrix与Tetrao属中其它物种的分歧小于松鸡科其它属间分歧,且黑琴鸡聚在Tetrao内,研究结果倾向支持黑琴鸡归于松鸡属Tetrao。The mtDNA cytochrome c-oxidase （COⅠ）, an important gene as DNA barcodes, is a very good tool for species identification. Now it has been widely used for phylogeny studies of birds. The COⅠ sequences of the Tetrastes bonasia and Lyrurus tetrix were sequenced in this study. The COⅠ sequence variations and phylogenetic relationships of 13 species of Tetraonidae were analyzed, combined with homologous sequences from GenBank. The results show that variations of interspecies is higher than that of intraspecies in Tetraonidae. Sequence variations and phylogenetic relationships show that the Tetrastes bonasia belongs to Tetrastes of Tetraonidae. The variations among Lyrurus tetrix and other species of Tetrao genus is lower than that among other genus in Tetraonidae. The Lyrurus tetrix was clustered in Tetrao genus in phylogeny tree. The results suggest Lyrurus tetrix belongs to Tetrao genus.
