Oregon State University

Oregon State University has been conducting research on hazelnuts since 1969. This research has focused on the development of new hazelnut cultivars for the Oregon hazelnut industry, eastern filbert blight resistance, microsatellite marker development, and DNA markers for eastern filbert blight resistance. Part of this work includes wide germplasm exploration and collection to increase the world’s largest hazelnut germplasm collection. In addition to research Oregon State University provides significant extension and outreach to the Oregon Hazelnut Growers, Scientific Committee of International Congresses on Hazelnuts, and Northern Nut Growers.
