ALLOZYME VARIATION IN POPULATIONS OF PINUS-SYLVESTRIS L FROM A 1912 PROVENANCE TRIAL IN PULAWY (POLAND)

Study of the genetic variation and genetic structure of 13 populations of Pinus sylvestris from Eastern Europe and Turkey has shown signific ant genetic differentiation of the populations. The average genetic di fferentiation (index GST) is high (0.076), but it is about 50 % lower in populations from the area covered by ice during the last glaciation (GST = 0.035). The mean multilocus heterozygosity for 8 loci (Ho = 0. 357) and the average number of alleles per locus are similar to those from the other parts of Europe. The genetic similarities of population s (Nei) are not correlated with the geographical localities of the stu died stands.
