Title: An analysis of methods for the selection of trees from wild stands

Author: Ledig, F. Thomas;

Date: 1976

Source: Forest Science 20(1):2-16

Publication Series: Miscellaneous Publication

Description: The commonly applied comparison-tree method of selection is analyzed as a form of within-family selection. If environmental variarion 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 allernate techniques for applying cite corrections in the selection of superior trees is suggested.

Keywords: Pinus rigida, base-line selection, phenotypic selection
