Similar to other boreal regions of Canada, northwestern Quebec has abundant lands available for the establishment of high-productivity plantations. However, few genetically improved species have been tested for this region. Three sites were planted with five hybrid poplar clones; 19 families of white spruce (Picea glauca [Moench] Voss) of southern Ontario and Quebec origins; 20 families of Norway spruce (Picea abies [L.] Karst.) of northeastern European origins; and a local seed source of white spruce. Survival and productivity were evaluated during their first three growing seasons. Survival rate was high for all selected plant material. For white spruce, genetically improved families were more productive than the local seed source. The use of exotics (Norway spruce or P. maximowiczii hybrids) did not confer any growth benefit at this early stage.
