Stable genetic resistance to the fungal disease eastern filbert blight (EFB), caused by Anisogramma anomala , is vital for sustainable production of European hazelnut ( Corylus avellana ) in eastern North America. In this study, new hazelnut germplasm from the Russian Federation, Ukraine, and Poland (a total of 1844 trees from 66 seed lots) was subjected to A. anomala under field conditions over at least five years in New Jersey. Plants were then rated for the presence of EFB using an index of 0
