	abstract = {Estimates of additive genetic correlations (r,) between wood extractive concentrations in heartwood of Scots pine (Pinus sylvestris L.) at two sites in northern Sweden were found to be high, on average, while their ge-netic correlations with tree growth were less clear. In a full-sib 25-year-old progeny test, r, was estimated to be about 0.7 between pinosylvins and resin acid contents, and about 0.9 between specific compounds within the pinosylvin and resin acid groups. The saturated fatty acid contents were also correlated with pinosylvins and resi? acid contents (r, = 0.4 to 0.8), while genetic correlations involving unsaturated fatty acids were low-er, and less distinctly expressed. Concentrations of sterols were negatively correlated (r, = -0.6) with those of other wood extractives. Similar patterns were found, confirming these trends, in another, 44-year old, full-sib progeny test. The generally high heritabilities recorded for production of fungitoxic substances (pinosylvins and resin acids), and the apparent absence of negative genetic correlations with tree growth or heartwood for-mation, suggest that each of the studied traits could be considered for inclusion in commercial tree breeding programs.},
