A Seed Source Study of Slash Pine within the State of Georgia

The economic importance of geographic races in forest trees has been recognized for about 75 years (Baldwin and Shirley, 1936). In southern pines, an experimental plantation established at Bogalusa, La., in 1926-27, shows that distinct and economically important geographic races exist even within the southern half of the range of loblolly pine (Pinus taeda L.). These races indicated important differences in tree size, volume of wood produced, and susceptibility to southern fusiform rust (Cronartium fusiforme Hedgecocke and Hunt) as reported by Wakeley (1944). Conversely, Crow (1958) found no effects at the end of 4 years in a test using loblolly pine seed from five locations in Louisiana, 20 to 180 miles from the planting sites.
