Book excerpt: Excerpt from Cone and Seed Yields in Young Western White Pines In the course of breeding western white pine (pinus monticola Dougl.) for resistance to blister rust (see Bingham, Olson, Becker, and others. 1969 and earlier), 18 years of data on cone and seed yields of individual trees from different geographic local ities have been accumulated. The protection of cones during development minimized losses due to insects and rodents; therefore, these data simulate the full reproductive potential of young trees in natural stands. Annual variation in cone production among geographic localities and individual trees thus is represented in these data. This information is indis pensable for practices of seed collection and seed orchard management which rely on knowledge relating to cone yields of individual trees and possibly on yields derived from controlled pollinations.
