The stem canker disease eastern filbert blight (EFB), caused by <i>Anisogramma anomala</i>, is a major impediment of European hazelnut (<i>Corylus avellana</i>) production in the United States. While most European hazelnut cultivars are highly susceptible to the pathogen, which remains confined to North America, EFB resistant and tolerant genotypes occur in the gene pool at low frequency. At Rutgers University, New Brunswick, NJ, USA, 5,226 trees were grown from open pollinated seeds collected f
