title: Genetic diversity in natural populations of Pinus nigra Arn. in Bulgaria
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 (averag
