Abstract
- Comparative analysis of allozyme variability was carried out by 18 loci from such tree-groups as 3 Pinus sylvestris L. natural steppe populations and a sample of 36 resistant trees from artificial stands in root fungus (Heterobasidion annosum (Fr.) Bref.) damage centres. Resistant trees are characterized by the least portion of polymorphic allozyme loci, by allele and genotype number, and by similar to midpopulational level observed and expected heterozigosity. Resistant tree sample differed from natural populations on composition and frequencies of multi-locus genotypes Dia-1, Lap-1, Acp, which are making the most contribution to researched tree-stands subdivision.
