Abstract

We studied genetic structure of populations of Karelian birch Betula pendula var. carelica (Mercklin) Hämet-Ahti, whichlacks second growth. Based on the values of expected and observed heterozygosity, the predominantselection of homozygotes on the background of decrease of the heterozygotes fraction was revealed. Interpopulation differentiation rate (Fst = 0,145) indicates a high inbreeding frequency. Observed genetic characteristics of the populationssuggest that genetic mechanisms play a role in the current decrease of thepopulation size of Karelian birch and its genetic degradation.
