Abstract The possible use of hybrid poplar for intensive production of pulpwood in the United States has attracted interest during the past 20 years. Hybrid poplars represent the fruition of efforts to cross-breed most of the poplar species of the world. Developments from the first significant forest-tree-breeding project in this country are noteworthy. At this stage, factual contributions on hybrid poplar performance may best determine their place in forest practice.
