Genetic Differentiation of Spruce Populations in Northwest Russia According to the Results of Microsatellite Loci Analysis
Analysis of the genetic diversity of the spruce populations in the northwest of the European part of Russia using microsatellite markers revealed two relatively isolated genetic clusters. One of them is com posed of trees that were identified as P. abies according to morphological traits. Another cluster unites spruces that were determined as P. obovata and P. fennica. The results of SSR analysis do not support the idea of the taxonomic independence of the hybridogeneous P. fennica species. The frequency of genotypes attributed to P. abies (according to the results of microsatellite markers) decreases significantly from south to north.
