Evolutionary history, systematics and taxonomy of charrs of the genus Salvelinus and especially of the representatives of the S. alpinus–S. malma species complex remain confused that is connected with a substantial ecological and morphological flexibility of this group and with supposed ancient hybridization between some taxa. For the analysis of phylogenetic relationships and introgressive hybridization between the species of the genus Salvelinus including three endemic species from Lake El’gygytgyn and all main representatives of the S. alpinus–S. malma species complex, nucleotide sequences of the mtDNA control region and two nuclear genes (ITS1 and RAG1) were analyzed. The differences in the topologies of individual gene trees, among other reasons, were connected with incomplete lineage sorting and historical introgressive hybridization between certain taxa. Several cases of mtDNA capture by different taxa and phylogenetic groups were proposed. Main phylogenetic groups of the S. alpinus–S. malma species complex were revised. The origin and phylogenetic relationships of southern Dolly Varden from North America were not unambiguously defined. We proposed that introgressive hybridization had an important role in the evolutionary history of charrs, in particular, in the appearance of a high level of morphological, ecological and taxonomical diversity.

Salvelinus属炭，特别是S. alpinus – S. malma种复合体的炭疽的进化历史，系统学和分类学仍然令人困惑，这与该群体的实质性生态和形态灵活性以及某些物种之间的古老杂交有关分类单元。为了分析Salvelinus属的物种之间的系统发育关系和渗入杂交，包括来自El'gygytgyn湖的三种特有物种和S. alpinus – S. malma的所有主要代表物种复杂，mtDNA控制区和两个核基因（ITS1和RAG1）的核苷酸序列进行了分析。除其他原因外，单个基因树的拓扑结构差异与某些类群之间不完整的谱系分类和历史渐渗杂交有关。提出了不同的分类和系统发生群体捕获mtDNA的几种情况。高山链球菌–马尔玛链球菌的主要系统发生群物种复合体进行了修订。北美南部多莉·瓦尔登（Dolly Varden）的起源和系统发育关系没有明确定义。我们提出，渗入杂交在炭黑的进化史中，特别是在形态，生态和分类学多样性高的外观上具有重要作用。
