The least allelic diversity and the least level of the observed heterozygosity (Но= 11,6%) are peculiar to Swiss stone pine, and the highest heterozygosity is peculiar to Stankewiczii Pine (Но=21,6%). All three species are characte- rized by a low genetic subdivision and differenti- ation of populations. Old trees of Chalk Pine dif- fered by the lowest values of every index of genetic polymorphism, especially by the level of the obser- ved and expected heterozygosity, as compared to more young age groups of plants from populations of this species. Relict populations of Scots pine from Kremenets Hills had the higher level of gene- tic polymorphism than those of Ukrainian Carpat- hians, and approximately equal to Chalk Pine po- pulations from the Donetsk region. All populations of the three investigated species had a very close to the equilibrium by Hardy-Weinberg's law genetic structure.Allelic structure of trees from relict popu- lations of Scots pine, Chalk Pine, and Crimean black pine is fully reproduced in their seed proge- ny, and a genotypic structure is declined from the equilibrium because of the excess of homozygous genotypes. Seed productivity of Chalk Pine, Norway spruce, and Scots pine is high both in their populations and stands. Heterozygosity level of Chalk Pine seed progeny maintained at identical level in the harvest of two consecutive years and changed in Crimean black pine populations from Mountain Crimea. In a primary introduction stand of Norway spruce allelic diversity considerably decreases as compared to natural populations, but their level of heterozygosity is maintained. Trees of Chalk Pine and Swiss stone pine substantially differ within one population on heterozygosity as well as their seed progeny. Marker loci, producing a plenty of heterozygous seed, are defind and patented for a Chalk Pine and developed for the Swiss stone pine for selection in populations oftrees.
