Fusiform Rust and Pitch Canker Resistance in Loblolly Pine Elite Varieties

Loblolly pine elite clonal varieties of Atlantic Coastal Plains (ACP) origin were screened for fusiform rust and pitch canker resistance in tests involving artificial inoculations. The screenings were done by the USDA Resistance Screening Center (RSC) in Asheville, NC over the course of four years. Twenty two related and unrelated varieties were challenged with rust inoculum developed from aeciospores collected in three regions representing large sections of the eastern, central and western distribution range of loblolly pine. The inocula from the three regions were not mixed. Pitch canker resistance screenings involved eleven varieties challenged with mixed inoculum from three southern ACP sources.
