The nucleotide sequences of the nuclear rDNA ITS regions were determined for 34 species of the genus Primula L. and one species of the genus Cortusa L., family Primulaceae Vent., and used to infer the phylogenetic relationships among these species. This analysis species of the Russian flora and the flora of adjacent territories were studied for the first time. The results clarified the taxomic structure of the genus Primula and confirmed the entity of some of its sections; but not the subgenera sensu J. Richards. Our data do not support an independent status of the genus Cortusa, placing it as one of the terminal lineages of the section Cortusoides Balf. f. in the genus Primula.
测定了报春花科报春花属34种植物和假报春属1种植物的核糖体DNA内转录间隔区（ITS）的核苷酸序列，并用于推断这些物种之间的系统发育关系。首次对俄罗斯植物区系和邻近地区的植物区系进行了此项分析。结果阐明了报春花属的分类结构，并确认了其一些组的实体；但不包括J.理查兹意义上的亚属。我们的数据不支持假报春属的独立地位，而是将其作为报春花属中假报春组的一个末端谱系。
