Abstract

In order to analyze the genetic structure, subdivision and differentiation within and between two small isolated populations of the Crimea relict endemic, Pinus stankewiczii (Sukacz.) Fomin, electrophoretic analysis of the isozyme variation at nine enzymatic systems was carried out using 183 oldest trees. It was demonstrated that in populations of P. stankewiczii, 80% of the genes were in polymorphic state. Each tree was heterozygous at 19.1% loci, and at 21.6% loci in artificial 50-year-old plantation. The genetic structure of two populations was less differentiated (D N = 0.006), compared to their individual localities (D N = 0.008−0.009). Within-population subdivision of the diffusely dispersed populations was higher (F ST -G ST = 1.8–2.0%) than that of the populations themselves (0.8%).
