摘　　要：测定了浙江省５个地方鸡种及来航鸡（对照）线粒体Ｄ－环区的部分序列（５３９ｂｐ），构建了鸡种的分子系统树。在所测序列中共有２４个变异位点，变异率为４．４５％。结果显示，浙江省地方鸡种分为两支，有两个母系来源，一支为仙居鸡，它和外来品种来航鸡关系较近，有共同的母系祖先。另一支为灵昆鸡、白银耳鸡、乌骨鸡和萧山鸡，它们有着共同的母系祖先，其中灵昆鸡，白银耳鸡、乌骨鸡关系较近，萧山鸡与此３种鸡关系较远。A lotal of 539 bases of mitochondrial DNA D-loop region of five native chicken breeds of Zhejiang Province and the white leghorn chicken (as the control) were squenced by DNA sequencing technique, and the phylogenetic trees of the chicken breeds were constructed. The results showed that 24 variation sites i.e. 4.45% sequence divergence were detected among the 30 DNA sequences, and the six breeds belonged to two different maternal lineage, one included Xianju chicken and White Leghorn chicken which had the same maternal origin, the other included Lingkun chicken, Baiyiner chicken, Wugu chicken and Xiaoshan chicken which had the same matriarchic ancestor. Among the latter lineage, Lingkun chicken, Baiyiner chicken and Wugu chicken had a closer relationship to each other than to Xiaoshan chicken.
