Genetic analysis of lodgepole pine (Pinus contorta) solid-wood quality traits
Potential improvement of lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) solid-wood properties was examined by estimating age trends of inheritance, age-age genetic correlations, and the efficiency of early selection using 823 increment cores sampled from 207 half-sib families...
