The disease eastern filbert blight (EFB), caused by Anisogramma anomala, has prevented commercial hazelnut ( Corylus avellana) production in eastern North America. Recently, several new sources of resistance to EFB have been identified and genetic improvement efforts are underway in multiple regions of the U.S. to develop adapted, disease-resistant cultivars. However, the wide genetic diversity of the pathogen may confound breeding efforts. In this study, we examined six sources of EFB resistanc
