Proceedings of the Fourth International Workshop on the Genetics of Host-Parasite Interactions in Forestry: Disease and Insect Resistance in Forest Trees. General Technical Report PSW-GTR-240. Albany, CA: U.S. Department of Agriculture, Forest Service, Pacific Southwest Research Station. 372 p. The Fourth International Workshop on the Genetics of Host-Parasite Interactions in Forestry: Disease and Insect Resistance in Forest Trees provided a forum for research and management options and successes which have occurred over the last 30 years (the previous workshop was held in 1980 in Wageningen, The Netherlands). Eighty-eight submissions from oral and poster presentations at the 2011 workshop held in Eugene, Oregon provide a worldwide, comprehensive update on many aspects of research and operational programs on genetic resistance to forest insects and diseases. Topics of concern to natural forest systems and intensively managed forests are discussed, including resistance mechanisms, durability of resistance, ecology and evolutionary biology of resistance and tolerance, pathogen evolution, molecular tools, shortterm screening assays for resistance and status of several applied forest tree resistance programs. Key words: forest disease and insect resistance, evolutionary biology, climate change, durable resistance iv Contents Mechanisms of Resistance to Pests and Pathogens 1 3 Tree Breeding for Pest Resistance for the Next 50 Years: The Search for Cross Resistance?
