[Characterization of the Bellevalia sarmatica (Georgi) woronow populations from Volgograd oblast using molecular genetic identification].

DNA samples obtained from the populations of the Red Data Book species Bellevalia sarmatica (Georgi) Worovow from Volgograd oblast were examined using RAPD and AFLP analyses. DNA marking revealed considerable differences in the levels of interpopulation and intraspecific polymorphism of the Bellevalia. Furthermore, RAPD analysis, despite of lower levels of interpopulation polymorphism identified, made it possible to obtain clearer data on population subdivision upon statistical treatment of the results. The results of this study can be used in developing conservation strategies for maintenance of the species abundance and genetic diversity, as well as in elaborating the criteria for construction genetic collections.
