present throughout the entire hazelnut-producing area in Oregon. GERMPLASM IMPROVEMENT Oregon State University's Hazelnut Breeding Program run by Dr. Shawn Mehlenbacher responded to the threat of EFB by developing EFB-resistant cultivars. The breeding
scouting, pruning, and spraying to control this disease ( Mehlenbacher, 1995 ). The resistance from ‘Gasaway’, an obsolete pollinizer ( Mehlenbacher et al., 1991 ), has been extensively used in the hazelnut breeding program at Oregon State University (OSU
The European hazelnut ( Corylus avellana L.) is one of the world's major nut crops. Its geographic distribution extends from the Mediterranean coast of North Africa northward to the British Isles and the Scandinavian Peninsula, and eastward to

-term management solution ( Julian et al., 2008 , 2009 ; Thompson et al., 1996 ). Breeding for EFB resistance is now a major objective of hazelnut breeding programs in the United States ( Mehlenbacher, 1994 ; Molnar et al., 2005a ). Recent taxonomic studies
EFB-resistant cultivars and breeding selections, one of the major impediments to developing a commercial hazelnut industry in parts of eastern United States has been greatly diminished. As such, it is important to examine other factors critical to
North America where hazelnuts are now grown as well as those regions suitable for future production. Therefore, the identification and development of cultivars resistant to the disease is a necessary objective of hazelnut breeding programs in North
