摘　　要：长期以来对血雉Ithaginis应划归雉类还是鹑类和是多型属还是单型属一直存在着争议。在此对3个亚种,西藏亚种Ithaginiscruentus tibetanus,甘肃亚种I.c.berezowskii和四川亚种I.c.geoffroyii的6个个体的血雉与典型的雉类雉属Phasianus、锦鸡属Chrysolophus、长尾雉属Syrmaticus及典型的鹑类石鸡属Alectoris、鹌鹑属Coturnix和雪鸡属Tetraogallus的线粒体DNA细胞色素b的部分基因序列比较,系统进化树中血雉与雉类聚在一起。根据血雉地理分布,多亚种中心理论,区域地理历史,环境演变和分子钟指示的时间,血雉可能于早上新世起源于横断山脉。3个亚种之间序列差异为4.1%~7.2%,与雉科其它属的种间差异度比较,其遗传分化已达到种的水平,与形态差异相吻合。The phylogenetic relationships of Ithaginis should belong to Phasianini or Perdicini,monotype genus or multi-type genus have been remained controversy.We analyzed the sequence of Cyt b gene 6 individual in 3 subspecies of the Ithaginis.Comparison typical Perdicini（Alectoris,Coturnix,Tetraogallus）and typical Phasianini（Phasianus,Chrysolophus,Syrmaticus）in Phasianidae,the Phylogenetic tree showed that Ithaginis should be classified into Phasianini.According to their distribution,the theory of multi-subspecies centre,geographic history,changed evironment and the time of molecular clock,that the ancestors of Ithaginis might have origin in Hengduan Mountain Region during early Pliocene.Considing the divergence of the subspecies,we discovered that the difference among these three subspecies of Ithaginis were 4.1%-7.2%.Compared with species of other genera,the genetic divergence among the three subspecies of Ithaginis was up to distinct species,which is in consistent with the morphological difference.
