Abstract
A molecular genetic analysis of horologically related populations of Pinus sylvestris L. was carried out. In the east and northeast of the East European Plain using intermicrosatellite analysis of DNA polymor-phism. Data on the genetic diversity of populations were obtained and the state of their gene pools was assessed. The studied populations of Scots pine have a high genetic diversity (P95= 0.938, HЕ= 0.170, ne= 1.540). Of the 144 DNA fragments, only 3 (0.021%) are rare. The analysis of the share of rare alleles showed that the genetic structure is less balanced in the populations of Verkhnevetluzhskaya (h= 0.254) and Vetluzhsko-Vyatka (h= 0.273). The most balanced genetic structure was observed in the Moloma population (h=0.112) and in the North Vyatka-Uvala population (h=0.127). When assessing the state of gene pools, it was found that the highest values of the coefficient of genetic originality (CSR) were found in the populations of Sysolo-Vychegodskaya (1,164) and Volga-Vetluzhskaya (1.140). This indicates the high specificity of the gene pools of these populations. The lowest values of CLO were determined in the Vetluzhsko-Vyatskaya (0.857) and Volzhsko-Surinskaya (0.875) populations. Analysis of all three groups of indicators of the state of gene pools of populations showed that, taking into account the genetic structure and genetic originality, 6 populations of P. sylvestris have a satisfactory state of gene pools, and two populations (Verkhnevetluzhskaya and Vetluzhsko-Vyatka) have depleted gene pools. When selecting trees for conservation and reforestation, it is necessary to preserve populations with both typical and specific gene pools.
