Abstract:

The commonly applied comparison-tree method of selection is analyzed as a form of within-family selection. If environmental variation among comparison- and select-tree groups, c², is a relatively small proportion (17 percent or less with 5 comparison trees) of the total variation, comparison-tree selection will result in less genetic improvement than individual-tree selection. Even if c² is large, individual-tree selection may be more effective than comparison-tree selection if comparison and candidate trees are related. Estimates of c² and of relationships among trees in wild stands derived mainly from published reports suggest that comparison-tree selection may in fact result in less genetic gain than individual-tree selection in many tree species. In any case, comparison-tree selection will seldom be much more effective than individual-tree selection. Development of alternate techniques for applying site corrections in the selection of superior trees is suggested. Forest Sci. 20:2-16.
