The article presents information on interspecific relations of 8 characteristic taxa of the genus Papaver L. of Transbaikalia, Pribaikalye and Eastern Sayan. A molecular genetic study of poppies in the region and their relationship to the endemic of the coast of the lake Baikal Papaver popovii Sipl. Because of a comparative analysis, data on the relationship of poppies of the Baikal Siberia were obtained. Relationships between the species of P. rubro- aurantiacum, P. pseudocanenscens and P. setosum, uniting into one clade, are revealed. On the other hand, the analysis of samples from different Transbaikalian populations of the same species of P. nudicaule showed their heterogeneity and, at the same time, they also had some morphological differences. The study results confirmed the independence of the endemic taxa Papaver popovii Sipl. However, genetic analysis revealed its proximity with another endemic species of the western coast of Lake Baikal — P. olchonense. It should also be noted that the analysis of the phylogenetic tree confirmed the independence of such species as P. croceum and P. czekanowskii. The position of P. rubro-aurantiacum, which forms the subclade from the relationship of P. setosum — P. pseudocanenscens, deserves attention.
