variation was studied in 17 populations of Pinus sylvestris from Northern and East-Central Europe. Populations from Scandinavia, northern Poland, Holand and Belgium are more heterozygotic, more polymorphic as far as genotypes are concerned; they also have a higher number of alleles per locus. The populations are in the Hardy-Weinberg equilibrium as can be judged from fixation indices. Genetic differentiation between populations (GST) in the studied group is low (2.3%). Populations from Norway, Finland, northern Poland, Germany and Holland form one genetically similar but heterogenic group. A population from Scotland is connected with this group. Populations from Latvia, Lithuania and Ukraine constitue the second group. The remaining populations show a varying degree of genetic similarity to the latter group.
