Abstract: Totally 26 provenance stands of 17-year-old Pinus koraiensis were selected for investigating genetic variation in different provenances and the trend of radial variation of wood quality in the direction of cone to tree bark.The results showed that:there was significant difference in wood quality between different provenances;All the wood property investigated showed radial variation trend.Tracheid length, tracheid diameter, growth ring density and late wood percentage increased with higher growth ring year.But growth ring width showed reverse radial variation.This research would provide basis for early selection and prediction of Pinus koraiensis wood quality.

Key words: Provenance of Pinus koraiensis, wood quality, genetic variation, radial variation
