We have analysis of ISSR-markers polymorphism of seven populations of Larix sibirica Ledeb., cultural and natural origins, located in the Perm and the Sverdlovsk regions. It was found 119 ISSR-markers, of which 116 (P95=0,974) were polymorphic. Seven studied populations of L. sibirica had different levels of genetic diversity. When comparing the three groups of populations, genetic variability was higher in cultured populations and in natural populations of the mountainous part of the Urals, it is lower in natural populations of the flat central part of the Perm region. We defined the genetic structure of populations and found that the studied seven populations highly differentiated (GST=0,543). We have made recommendations for developing programs for the conservation and reproduction of populations of L. sibirica.
