Using the isozyme analysis, genetic variations in six species of the genus Oxytropis DC. (Fabaceae) from Kamchatka was assessed. It was demonstrated that diploid species from the section Arctobia were characterized by a low level of variations typical of endemic plant species. At the same time, polyploid species from the Orobia section demonstrated very high values of the heterozygosity parameters (H o varied from 0.200 to 0.274). It has been suggested that the level of polymorphism of the oxytropes from Kamchatka was shaped as a result of the interaction of a number of factors, among which the most important are the ecological confinedness of the species, the specific features of the reproductive system, and gene drift. In the species of Orobia section, it is also the presence of the polyploid genome.
