Analysis of genetic diversity and structure of Urals populations of western race of Siberian larch (Larix sibirica Ledeb.) based on intermicrosatellite markers polymorphism

The preservation of the genetic diversity of a species is possible only if the gene pool of its populations is preserved. Particularly important are studies of patterns of distribution of genetic variability for species that occupy vast areas and are of economic importance, such as species of the genus Larix Mill. The purpose of this study is to analyze the genetic diversity and structure of some populations of L. sibirica of Ural based on intermicrosatellite polymorphism. Using the ISSR markers, the genetic diversity and structure of 6 natural populations of Siberian larch L. sibirica in the Urals were analyzed. The analysis revealed 120 ISSR markers, of which 116 were polymorphic (P95=0.967). The main parameters of the genetic diversity of populations were determined and it was shown that the Ural populations of Siberian larch are characterized by a higher genetic diversity. At the same time, the highest rates of genetic diversity were found in the VSN population (P95=0...
