Abstract
The results of a comparative study of the genetic structure, parameters of intraspecific genetic diversity, and spatial differentiation of 35 populations of Picea abies–P. obovata–P. koraiensis species complex, located within the areas of distribution of “pure” species and in the contact zones of their ranges were presented. P. abies populations from Eastern Europe (Belarus, Poland); spruce populations from the European part of Russia, the Urals, and the West Siberian Plain, located in the zone of P. abies and P. obovata introgressive hybridization; P. obovata populations from various parts of the extensive range of this species in Siberia and Mongolia; and P. koraiensis populations from the Russian Far East and Northeast China were analyzed. The study of genetic variability and differentiation of populations was based on the analysis of variability of three microsatellite loci: Pt63718, Pt71936, and Pt26081, developed on the basis of Pinus thunbergii Parl chloroplast genome. The use of these DNA markers made it possible to obtain data indicating a fairly high degree of P. koraiensis genetic divergence from two other spruce species included in the complex, P. abies and P. obovata. Korean spruce growing in the Far East differs significantly from the populations of these species in the number and composition of haplotypes, the level of genetic diversity, and population structure, which gives us reason to consider it as a separate species.
