Variation in Rust Resistance in Mississippi Loblolly Pine

Stands with a high degree of resistance were located in Florida parishes of Louisiana and southwestern Mississippi. Stands nearest the Gulf Coast in Alabama and Mississippi were least resistant, and resistance increased gradually to the north and west. There were more highly resistant stands along the western margin of the range in Mississippi thanalong the Mississippi-Alabama border. Attempts to correlate these results with the distribution of shortleaf pine (Pinus echinata Mille) were only partially successful.
