Abstract
Samples of trees and seed embryos of five Pinus kochiana Klotzsch ex Koch populations in Crimea were comparatively studied at 12 allozymic loci for its genetic variability and mating system. It has been shown that the embryos of seeds reproduce the allelic diversity of maternal plants, but the level of their observed heterozygosity (Ho) is significantly lower, i.e., 0.286 vs. 0.189, respectively. Unlike maternal trees, embryos are characterized by a significant divergence between the observed distribution of genotypes and the theoretically expected one according to the Hardy–Weinberg law for the majority of analyzed loci. The frequency of cross pollination in populations varied from 0.384 to 0.673 according to single-locus (ts) estimates and from 0.639 to 0.841 according to multilocus (tm) estimates.
