Nahla Bassil, Shawn Mehlenbacher This success story describes how the pollinizer hazelnut, ‘Gasaway’, saved the U.S. hazelnut industry. Plant breeders used ‘Gasaway’ as a source of Eastern filbert blight resistance to breed new pollinizer hazelnut, as well as ornamental and nut cultivars. The ‘Gasaway’ source of resistance can now be identified in saplings using DNA tests.
