Genetic variation and gains of specific gravity and woody biomass in a jack pine half-sib progeny test in Michigan

Specific gravity and growth characters were analyzed in a half-sib progeny test of jack pine (Pinus banksiana Lamb.) located in the Upper Peninsula of Michigan and comprised of northern Lower Peninsula families. Significant family differences were found for specific gravity, diameter, volume and wood mass. Combined selection at both the family and within-family levels for single and multiple trait indexes were evaluated using gains in woody biomass for comparison. Combined selection for volume at the family level and specific gravity within families may produce the most efficient gain in woody biomass when costs of evaluation are considered. Additional keywords: Heritability, combined selection, Pinus banksiana.
