Genetic Variation In Mississippi Sweetgum

Seed was collected from 650 sweetgum trees throughout Mississippi and southeastern Louisiana during 1962, 1963, and 1964. Progeny plantings were established in south Mississippi, central Mississippi, and southwest Tennessee. After 10 years, well defined latitudinal and longitudinal patterns of variation in height growth were evident among the half-sib progenies. Progenies from southeastern Mississippi excelled in all three plantings, but the zone of fastest growth for the northernmost planting was farther northwest than for the other plantings. Progenies from near the Mississippi-Alabama border grew faster than those from the floodplain of the Mississippi River or the loessal hills that border the floodplain to the east.
