摘要: 选用叶绿体rbcL基因对鸢尾属植物的分类和系统发育进行了分析。以雄黄兰为外类群,对21份鸢尾属材料和GenBank下载的共49条序列采用最大简约法构建系统进化树,探讨了鸢尾属的分类系统。针对有争议的物种,聚类结果表明:马蔺与白花马蔺关系较远;扁竹兰和蝴蝶花亲缘关系较扇形鸢尾近;细锐果鸢尾和锐果鸢尾亲缘关系近,大锐果鸢尾较之远;四川鸢尾和薄叶鸢尾聚类近;西伯利亚鸢尾系内物种间聚类复杂,亲缘关系不清楚。

Abstract: The phylogenesis of Iris L. was analyzed using the chloroplast genes rbcL. Classification was performed with maximum parsimony method and the gene tree were constructed with Crocosmia crocosmiflora as outgroup, 21 wild populations of Iris L. from China and download 49 sequences from GenBank. As for disputed species, clustering trees results showed Iris lactea var. chinensis(Fisch.) Koidz. had close relationship with Iris lactea Pall.. Iris confusa Sealy had more close relationship with Iris japonica Thunb. than that with Iris wattii Baker. Iris goniocarpa var. tenella Y.T. Zhao was very relevant to Iris goniocarpa Baker, but Iris goniocarpa var. grossa Y.T. Zhao was distant. Iris sichuanensis Y.T. Zhao and Iris leptophylla Lingelsh. were closely related. Clustering relationships of Series Sibirica were very complexed, and genetic relationgships were not clear.

Key words: Iris L., rbcL sequence, systematic classification
