<abstract xmlns="http://www.w3.org/1999/xhtml">The analysis of chosen selected Scots Pine (Pinus sylvestris L.), populations representing different seed regions: 107 (Międzyzdroje), 305 (Woziwoda), 206 (Strzałowo), 208 (Białowieża), 504 (Bolesławiec), 606 (Józefów) were performed using 10 isoensyme markers: Gdh (E.C.1.4.1.2), Sdh-A, Sdh-B (E.C.1.1.1.25), Pgd-B (E.C.1.1.1.44), Mdh-A, Mdh-C (E.C.1.1.1.37), Got-A, Got-B, Got-C (E.C.2.6.1.1), Dia-C (E.C.1.8.1.4). There were calculated following genetic parameters: allelic frequencies, observed and expected heterozygosities, and Wright’s fixation indexes. In populations, the results of analysis indicated presence of rare alleles. In all study populations, the average effective number of alleles per locus was 1.46 and was lower than expected number of alleles per locus of 1.93. The results for the effective number of alleles of the population per locus were as follows: Strzałowo and Białowieża 1.54, Bolesławiec 1.48, Jozefów 1.44, Świnoujście 1.42, Woziwoda 1.35. Average observed heterozygosity in the studied populations was calculated at the level of 0.26 and it was lower than the expected heterozygosity at 0.28. For populations, the level of heterozygosities were as follow: Strzałowo 0.35, Bolesławiec and Białowieża 0.25, Józefów 0.27, Świnoujście 0.23, Woziwoda 0.26. In particular loci level of heterozygosity was different, as the most heterozygous Mdh-C locus was estimated, while minimum Got-C. Significant differences in allele frequency of Hardy-Weinberg deviation equilibrium were found in 10 cases: Strzałowo (Got-C), Bolesławiec (Got-B), Białowieża (Got-B, Gdh), Józefów (Mdh-C), Międzyzdroje (Got-B, Got-C, Mdh-C), Woziwoda (Got-C, Gdh). All studied populations had a lower effective number of alleles per locus (Ne) comparing to the observed number of alleles (Na). Wright’s fixation indices were negative for populations: Strzałowo (-0.09), Józefów (-0.03), Międzyzdroje (-0.01) and positive for: Białowieża (0.12), Woziwoda and Bolesławiec (0.07). The extremely high Wright’s fixation index (0.12) was observed for Białowieża population.</abstract>
