Аннотация:In our study, two aggressive-invasive species, Lupinus polyphyllus Lindl. and Heracleumsosnowskyi Manden. from Russia and Ukraine, were investigated. The success in naturalizationof both species is associated with human activities, since they have been used in agriculture andfloriculture and both have qualities such as environmental tolerance, high fertility and phenotypicplasticity. The purpose of this study was to determine the level of genetic diversity of both species. ForHeracleum sosnowskyi Manden., genetic diversity was compared in invasive and native populations.For Lupinus polyphyllus Lindl., the genetic diversity was compared in variety, feral and invasivepopulations. A genetic diversity was formulated using RAPD, ISSR and REMAP. For Heracleumsosnowskyi Manden., the average genetic diversity within the invasive population was similar (0.432),but slightly less (0.502) than within the native Caucasian population. This may suggest the successfulnaturalization of invaders and almost complete reconstruction of their genetic diversity. For Lupinuspolyphyllus Lindl., the genetic diversity for the invasive population was the highest, with an averageof 0.294, while for variety, it was the lowest, with an average of 0.194. The feral population hadan intermediate place with an average of 0.248, which could suggest an increase of diversity in theprocess of naturalization.
