Abstract

All nine species of white pines (five-needle pines) native to the United States are highly susceptible to Cronartium ribicola, the fungus causing white pine blister rust. The presence of genetic resistance will be the key to maintaining or restoring white pines in many ecosystems and planning gene conservation activities. Operational genetic resistance programs are well underway for western white pine (Pinus monticola), sugar pine (P. lambertiana), and eastern white pine (P. strobus). However, very little is known about the frequency and types of resistance in the high elevation species of white pines, and in particular little or no data is available on family or seed source variation within species such as southwestern white pine (P. strobiformis, SWWP), whitebark pine (P. albicaulis, WBP), limber pine (P. flexilis, LP) and Rocky Mountain bristlecone pine (P. aristata, RMBCP).
