摘　　要：鉴于黑的分类归属一直未能有定论 ,本文中通过分析线粒体细胞色素b基因的序列 ,并重建亚科的系统发生 ,在此基础上探讨黑的分类归属。在重建的系统树中 ,亚科物种之间表现为平行枝的关系 ;亚科物种间的序列分歧在属内与两个属间之间变化不明显 ,提示亚科的物种可能是来自于一个快速辐射演化事件的群体。对细胞色素b基因的序列分析结果以及重建的分子系统进化树提示 ,将黑独立为Dupetor属是不适合的 ,因而我们支持Bock的观点 ,将黑置于苇属之内。There is still controversy on the classification of black bittern. In present study, we elucidated the its phylogenetic relationship within subfamily Botaurinae based on analysis of mitochondrial Cytochrome b gene sequences. The results showed that there was the parallel branches relationships among the species of Botaurinae based on phylogeny trees and no obvious divergence between inter-genera and intra-genera, which suggested that all species within Botaurinae possibly originated from a rapid radiation event. The results also indicated that black bittern should be put in Ixobrychus genus, instead of Dupetor genus, which was consistent with Bock′s opinion.
