- Abstract
The genetic diversity and differentiation of natural populations of Pinus nigra Arn. in Bulgaria was studied by isozyme gene markers. Sixteen populations were included in the study, representing the whole area of species' distribution in the country. Polymorphism and diversity parameters were relatively high and corresponded to the values reported in other studies on the species. Mean allele number ranged from 2 to 2.62 (average 2.24), effective number of alleles ranged from 1.12 to 1.45 (average 1.32) and percent of polymorphic loci - from 50 to 100. Observed heterozygosity ranged from 0.11 to 0.28. The differentiation among populations was low (7 %), which is typical for the species with similar life-history characteristics. The results could be useful in designing of management and conservation of Pinus nigra genetic resources in Bulgaria.
