Abstract One-year-old loblolly pine wind-pollinated families from Coastal North Carolina, Piedmont North Carolina, and Texas had different potentials for total height growth and different seasonal distributions of their height growth when grown near Raleigh, N. C. The performance of the sources was altered when they were grown on two artificial soils differing drastically in moisture and fertility conditions. Crosses of Coastal North Carolina X Texas and Piedmont North Carolina X Texas paralleled the performances of wind-pollinated parental families. Thus, the inter-provenance crosses confirmed the genetic basis of the patterns of height growth. Forest Sci. 18:205-210.
