Coastal Douglas-fir Wood Quality: Quantitative and Molecular Results

Interior lodgepole pine (Pinus contorta Dougl. ex. Loud. var latifolia) is the most heavily planted tree species in British Columbia, Canada. The lodgepole pine breeding program is in its second generation of progeny testing which incorporates two breeds: (A) height growth improvement and (B) height growth and relative density improvement. An ‘environmental map’ free of genetic effects, was considered important to develop strategic deployment approaches for materials coming from the A or B breeding groups. To achieve this, environmental variation in wood relative density in lodgepole pine was examined by sampling from a 33 year-old provenance test planted at 60 test sites across the range of the species in British Columbia, using a set of six standard provenances.
