Forest Genetics Research at the University of Georgia

Trees are being selected from various sites in different locations and for specific characteristics. At present our selections are being limited to the four major pines in the region. Future study may involve other species, both gymnospermous and angiospermous. Selections are to be made on the bases of: clear length of stem and tree height, taper of stem, straightness of grain of wood, diameter of branches, angle of branches, diameter of the bole, forking of the stem, straightness of stem, natural pruning ability, apical dominance, narrowness of crown, seed production, flare of butt, sprouting of epicormic buds, wood density, cell size, cell wall thickness and the relative amounts of earlywood and latewood, fiber length, disease resistance and other characters as yet unclassified. At present selections are being made on the bases of form and vigor. Within these selected trees other qualitative factors will be considered.
