popup.description2
Population of Pinus sylvestris L. in the Ukrainian Polesie is characterized by low rates of allelic and genotypic diversity, level of heterozygosity generally found at the lower limit values, as described in the literature for this species. Lowland populations of P. abies from Ukrainian Polesie are characterized by high allelic and genotype diversity and low differentiation. Main indexes genetic polymorphism of P. abies of the Ukrainian Carpathians and Polesie can confirm the above expressed view that populations Carpathian subspecies predominant in the western part of the Ukrainian Polesie. Average heterozygosity 130-140-year-old plant relict populations of P. sylvestris (НО = 0.288, HE = 0.277) Kremenets hills and in the Maloye Polesiye significantly lower than that of 30-40-year-old tree plantations (НО = 0.358, He = 0.330) in the region. Observed heterozygosity of the seed progeny was significantly lower than that of plant of populations (HO = 0.169) and plantations (НО = 0.180). In archival-clonal plantation genetic structure of seed progeny is differed from the genetic structure of the parent plant, which is manifested in a high frequency of occurrence in seed progeny of significant deviations from the distribution of genotypes theoretically expected under the Hardy-Weinberg equilibrium.
