The phenotypic correlation between wood density and stem growth (tree height and diameter) was examined in young interior spruce. The sample trees represented 40 half-sib families in two progeny test sites in British Columbia. In general, the relationship was found to be negative and weak. There were individual trees and families that showed fast growth and above-average wood density. If genetic correlations are equal to or weaker than the phenotypic correlations, and if the correlations persist in mature trees, it would be possible to select individual trees and families for fast growth without reducing wood density.
