The phylogenetic relationship of Elymus species were analyzed by molecular phylogenetic methods. Comparative analysis of the sequences ITS1-5.8S rRNA gene-ITS2 of the nuclear genome species of genus Elymus and kinship group showed that the species of the genus Elymus have 3 haplotypes. Нaplotype A was found in Elymus species (sections: Turczaninovia, Goulardia и Elymus) and Elytrigia geniculata; haplotype B was found in Elymus species (sections: Turczaninovia, Goulardia); haplotype C (sections: Goulardia и Clinelymopsis) and E. repens. Comparative analysis of the sequences trnL-trnF of the chloroplast genome of genus Elymus related species showed that the species of the genus Elymus form strongly supported clade. The phylogenetic trees were constructed using Bayesian method. Refs 22. Figs 2. Tables 3.
