Abstract
Abstract Two 8-year-old grafted ramets from 12 lodgepole pine (Pinus contorta var. latifolia) ortets (wild stand parent trees) were sampled at each of three sites and were assessed for specific gravity with small diameter cores. The broad-sense heritability estimate from the analysis of variance was 0.62, but estimates derived by regressing clone means from ramets on ortet values were 0.49 and 0.54 for juvenile and mature wood, respectively. This relatively high repeatability for specific gravity suggests wild-stand ortet values may be useful for identifying low specific gravity clones in seed orchards, or potential low specific gravity families in breeding populations of lodgepole pine. West. J. Appl. For. 5(2):40-42, April 1990.
