Eastern filbert blight (EFB), caused by Anisogramma anomala , is a fungal disease threatening the european hazelnut ( Corylus avellana ) industry in the Willamette Valley of Oregon. The pathogen is endemic to the eastern United States where it causes little damage to the wild Corylus americana but causes severe cankers on most cultivars of the commercially important european hazelnut. The host genetic resistance in ‘Gasaway’ is conferred by a dominant allele at a single locus on linkage group 6
