%X The trees were divided into the dominant trees, the intermediate trees and the suppressed trees according to the height and diameter(ground diameter) parameters. The variation of genetic diversity characteristics in different dominance hierarchies of <i>Pinus yunnanensis</i> Franch. population was studied by SSR molecular markers. In forest canopy layer, the mean number of effective alleles, Shannon's information index, observed heterozygosity and expected heterozygosity of dominant trees were 2.083, 0.762, 0.290 and 0.423, respectively, for the dominant trees, which slightly exceeded the intermediate and suppressed trees. In regeneration layer mean number of effective alleles, Shannon's information index, observed heterozygosity and expected heterozygosity were 2.063, 0.774, 0.272 and 0.410, respectively, for the dominant tree, which slightly exceeded the intermediate and suppressed trees except for observed heterozygosity. There were no significant differences among the different dominance hierarchy trees for the genetic diversity by the difference significance test of statistics method.
