In young Virginia pine, narrow-sense heritabilities were 0.50 for height at age 1, 0.59 for height at age 8, and 0.33 for diameter at age 8. High simple correlations between heights at early ages and age 8 indicate that selection can be made at young ages, but the simple correlation between total height and annual height growth from age 5 to 8 did not become significant until age 8. This suggests selection should be delayed until at least age 8. Heritabilities for unextracted and extracted specific gravity were 0.38 and 0.41, respectively. Correlation of 0.98 between the two densities indicates that extraction is not necessary on 8-year-old material. FOREST SCI. 23:450-456.
