Comparative study of allozyme polymorphism in the samples of Pinus sylvestris L. trees with different seed productivity

Cytology and Genetics 2004, v 38, number 2, 9-14

Genotypes of 196 Pinus sylvestris L. plants from 10 natural populations of five Ukrainian regions have been determined using 19 polymorphic isozyme loci. Variability of quantity of full-grained, empty-grained and underdeveloped seeds in the cones of these plants has been studied. The basic indexes of genetic polymorphism were determined for 6 samples presented by 18-19 trees with high and low productivity of the full-grained, empty-grained and underdeveloped seeds. The maximum amount of rare alleles and genotypes as well as the highest heterozygosity (Ho = 0,285) were typical for the sample of plants with the maximum quantity of empty-grained seeds in the cones.
