Phenotypic Variability and Genetic Diversity in a Pinus koraiensis Clonal Trial in Northeastern China.

ABSTRACT: Combining phenotypic and genetic characteristics in a genetic variation study is of paramount importance to effectively orient the selection of producers' elite trees in a seed orchard. In total, 28 phenotypic characteristics and 16 microsatellite loci were used to analyze the clonal genetic variation, to characterize the genetic diversity, and to refine the genetic classifications of 110 Pinus koraiensis clones grown in the Naozhi orchard in northeastern China. All clones were significantly different in most traits. Most of the phenotypic characteristics showed great genetic variation among clones, while the genotypic differentiation was weak between the selection sites of clones. The SSR markers showed a relatively high level of genetic diversity (Na = 4.67 ± 0.43, Ne = 2.916 ± 0.
