Genetic Improvement of Hardwood Fiber Production in the North-Central Region: Potentials and Breeding Alternatives

We can assume from previous analysis by Dawson and Pitcher (1970) that genetic improvement of hardwood fiber species in the North Central Region is a high priority research and development goal. They conclude that effort should be concentrated on aspen and cottonwood for which there are respectively about 8 and 4 million acres of highly productive sites in the region. Most of my discussion will thus center on probable first generation genetic gains in these species, especially aspen, which have not been subjects of recent review. However, data will also be noted for other northern species such as birch, maple, and oak, for which highly justifiable breeding programs are aimed mainly at improvement of lumber and veneer material; improvement of these species' growth capacity can ultimately add to our fiber supply. Finally, I will briefly review recent data for some southern hardwoods, because they suggest first generation gains that may be expected in north-central species. We will consider growth, wood properties, and pest resistance.
