Performance Rating System (PRS™) data are available to all Full and Contributing Members. PRS™, and Spec Sheets can be readily generated for all loblolly pine families in the NC State Cooperative. Consulting foresters who are members can also assist landowners in making decisions about appropriate seedling families to plant and meet their objectives. Forest landowners should always plant adapted families of loblolly pine that have appropriate levels of genetic improvement for volume growth or productivity, disease resistance, with desirable stem form and wood quality. Landowners have options for replanting to find families to optimize their management plans.
Below are two examples of highly productive open-pollinated families available for planting in the Coastal Plain, but they differ significantly for rust, straightness, and adaptability. The “Choice Coastal OP3” family is a good grower and has average rust resistance and straightness scores and is more at risk for cold damage. “Superior Coastal OP7” family is a little less productive but has excellent rust resistance and straightness scores and can be pushed further north in the planting region.
