Hybrid Pines (Pitch Pine x Loblolly Pine) Studied in the Appalachian Region of Maryland

Hybrids of pitch pine x loblolly pine (Pinus rigida x taeda) originating from a cross of pitch pine (P. rigida) of unknown origin with loblolly pine (P. taeda) pollen from Georgia were studied in Garrett County, MD. At 17 years after planting, 53% of the hybrid trees survived; their heights averaged 7.8 m and their diameters (DBH) were 15.5 cm. Pitch pines and loblolly pines native to Maryland planted for comparison had similar heights and diameters, but the loblolly pines showed a high mortality rate-only 19% of the planted specimens survived.
