Commercial production of hazelnut (<i>Corylus avellana</i>) in Oregon's Willamette Valley is threatened by eastern filbert blight (EFB), a serious canker disease caused by the pyrenomycete <i>Anisogramma anomala</i> (Peck) E. Müller. The fungus also prevents the establishment of hazelnut orchards in eastern North America. Genetic resistance is considered the most effective way to control the disease. A high level of EFB resistance was first discovered in 'Gasaway'. This resistance is conferred b
