Abstract
Genetic resistance to white pine blister rust (WPBR) will play a critical role in the future trajectory of whitebark pine and the other high elevation white pines. However, as we found during the field trips at the WPEF Science Conference in September, the terminology associated with genetic disease resistance can get confusing, e.g. not all seed trees are plus trees and not all plus trees have genetic resistance.
