Its composition is variable among and within species. The ability to monitor the intra-specific variability is a prerequisite to improve wood and end-products properties. This paper describes a study of the genetic control of a large set of wood properties including growth timber quality traits wood chemical composition kraft pulp production parameters and pulp properties in a 12 X 12 half diallel of maritime pine Pinus pinaster Ait. . While relatively high h2s narrow-sense heritabilities were observed for density heterogeneity lignin content alpha-cellulose content and coarseness no significant genetic effect was detected for hemi cellulose water extractives kraft pulp production parameters and pylodin. Slightly lower heritabilities hns were also obtained for wood density and fibre properties length width curl zero
