Comparison of noble fir progeny from US Pacific Northwest collection regions and Denmark for Christmas tree traits

Noble fir is the leading Christmas tree produced in the US Pacific Northwest (PNW). This study is based on evaluations of 24,721 trees collected from five native collection regions in Oregon and Washington plus imported seed from Denmark. Traits important for commercial Christmas tree production were evaluated and include commercial height, tree grade, value and color.
