Generally accepted that F. moschata is a common element of the nemoral flora. Its area occupies the territory from western bourders of Europe and reaches the Ural Mountains on the East. From the last part of the XX century, data of detections of musk strawberries in plant communities in Western and Eastern Siberia, including the southern part of the Krasnoyarsk region, have been appeared. Locations of such cenopopulations of musk strawberry described for small-leaved forests (mainly) and fir forests of the Yenisei Sayan Mountains. The article aims to describe the phytocenotic confinement of growth in the Yenisei Sayan Mountains of two populations of F. moschata (samples No. 17-16 and No. 18-28), verified by cytogenetic tests and PCR diagnostics. We have shown that samples No. 17-16 and No. 18-28, in hybridization with experimental samples of F. moschata of European origin, form full-fledged achenes with germination characteristics of the species. To establish the species affiliation of the samples, we used a molecular marker - the alcohol dehydrogenase ( adh 1) gene. Comparing the DNA amplification result for samples No. 17-16 and No. 18-28 with primers specific for the adh 1 gene sequence showed the lengths of amplified fragments identity set for investigated samples to the F. moschata of European origin PCR profile. Comparison of the floristic similarity of these two plant communities, where the studied samples of F. moschata grow, showed little correspondence of these communities in species composition ( KJ = 0.2). This fact indicates the ability of F. moschata to develop not only ecological niches of small-leaved forests close to its needs (sample no. 17-16) but also fir forests (sample no. 18-28) in the Yenisey Sayan Mountains. The article discussed the origin (allochthonous or autochthonous type) of F . moschata population in the natural plant communities of the Yenisey Sayan Mountains on previous herbarium collections and our samples.
