Abstract

The Inter Simple Sequence Repeats (ISSR) analysis of 93 samples of a rare endemic species Allium regelianum, growing in Volgograd oblast is conducted for the first time. Using the six primers, 109 fragments are obtained, of which 87 (79.8%) are polymorphic. The intra- and interpopulation diversity of A. regelianum is estimated. The highest rates of intrapopulation diversity are noted for populations from Krasnoyarskii khutor, Serafimovichskii administrative region, and Khrenovatyi liman, Nikolaevskii administrative region. Analysis of the interpopulation differences revealed a relatively high level of similarity between populations and a low level of subdivision.
