Eastern filbert blight (EFB), caused by Anisogramma anomala , is a devastating disease of Corylus avellana , the European hazelnut of commerce, and is considered the primary limiting factor of production in eastern North America. Conversely, C. americana , the wild American hazelnut, is generally highly tolerant of EFB, although it lacks many horticultural attributes necessary for commercial nut production. Hybrids of C. americana and C. avellana combine the EFB resistance of the wild species wi
