OSU researcher Shawn Mehlenbacher continues to breed new varieties of hazelnuts that are resistant to disease. Oregon grows 99% of the nation’s hazelnut output—a $129 million industry. New plantings are increasing at a rate of 10%, or 300 new acres a year of OSU-bred varieties. OSU plans to license Wepster, the newest hazelnut variety, for a royalty of 50 cents per tree.
