Abstract
With the use of six polymorphic microsatellite markers of nuclear DNA in the territory of oil complex of Western Siberia’s activity, a pilot study of three closely spaced populations of Pinus sylvestris L. - bog land, dry land, and "technogenic" (originated on the sandy base of the drilling pad) was carried out. It showed that the studied populations are quite close in terms of the main parameters of genetic variability, assessed by six polymorphic loci. At the same time, small but statistically significant differences were found between the dry land and bog land populations, including one’s in FIS. The "technogenic" population has an intermediate position between the studied natural populations and does not show statistically significant differences from them. It has been suggested that the most likely cause of the latter is the formation of "technogenic" young pine stands from a mixture of genotypes of the dry land and bog land populations, as well as that the appearance of unique (private) alleles in the "technogenic" population and adjacent bog land population can be induced by chemical pollution.
