Blister Rust Resistant Western White Pine for the Inland Empire: The Story of the First 25 Years of the Research and Development Program

摘要

Methods, results, and conclusions are reviewed in the report for a 25-year, USDA Forest Service first-phase Research and Development program. The program goal was to attain useful blister rust resistance in western white pine. One study result is that the Service will be mass-producing second-generation, rust resistant white pines for the Inland Empire. About two-thirds of these seedlings are expected to withstand severe exposure to local races of blister rust.
