Abstract:

Open-pollinated Fraser fir (Abies fraseri [Pursh] Poir.) progeny from several elevations on each of 5 mountain sources were assessed at 8 yr (rotation age) for growth and quality traits. Seed sources varied significantly in total height, crown diameter, branch diameter, straightness, crown density, USDA Christmas tree grade, and Christmas tree value. Age 8 yr results were very similar to both 1 and 4 yr results; lower elevation, southern sources showed superior performance in most traits including wholesale value. The common commercial seed sources on Roan mountain performed poorly by comparison. Statistically significant seed source X location interaction found for height, crown diameter, branch diameter, and value proved practically unimportant. Top-ranked seed sources overall maintained superiority at all sites. Potential rotation age tree wholesale value gains to Christmas tree growers through changing from the current chief commercial seed source on Roan Mt. to superior seed sources may exceed 7%. South. J. Appl. For. 19(4):157-161.
