Western white pine (Pinus monticola Dougl.) is a wide-ranging forest tree with high economic and ecological value. However, several factors, including the inadvertent introduction of the non-native fungal pathogen (Cronartium ribicola Fisch), which causes white pine blister rust disease, has led to extreme levels of mortality in many natural populations of the tree.
The Washington State Department of Natural Resources and the U.S. Forest Service’s Dorena Genetic Resource Center have partnered to undertake a series of field trials to evaluate the success of developing genetically resistant populations of Western white pine.
This paper (Monitoring Blister Rust Resistance, Pathogen Virulence
and Genetic Adaptability of Western White Pine in
Washington and Oregon) explains more about the field trials and the early results.
