Fifth Year Performance Of Wide Ranging Loblolly Pine Provenances

Five provenances of loblolly pine were planted at six locations in north Florida and south Georgia. After five growing seasons, the East Texas source had the lowest fusiform rust infection in most tests and exhibited fair growth rate. The Livingston Parish source incurred surprisingly high rust infection, but generally ranked well in growth. Marion County, Florida and north Florida Seed Orchard stock grew well, but sustained high rust infection. The Eastern Shore of Maryland source was intermediate to East Texas and Livingston Parish in rust infection, but ranked lowest in growth in most tests. Livingston Parish and local sources are not recommended for planting in high rust hazard areas.
