Heritabilities and gains in volume, diameter and height for open-pollinated progeny of eastern white pine from the Cumberland Mountains

Open-pollinated progeny of 22 white pine selections were analyzed for volume, stem diameter, and total height, and compared with Southern Appalachian commercial check seedlings. The half-sib progeny, age 8 years, averaged 14.5 dm in volume, 7.05 cm in diameter, and 4.67 meters in height while the checks averaged 5.7 3 in dm in volume, 3.73 cm in diameter, and 3.07 meters in height. Family heritabilities of .84, .84, and .68 and individual tree heritabilities of .28, .25, and .24 were calculated for volume, diameter and height respectively. Gains of 43% for volume, 16% for diameter, and 9% for height are reported.
