‘Yamhill’ is a new hazelnut (Corylus avellana L.) cultivar for the kernel market. It was released by the Oregon Agricultural Experiment Station in Jan. 2008. It combines complete resistance to eastern filbert blight (EFB) caused by the fungus Anisogramma anomala (Peck) E. Müller with high nut yield, early nut maturity, high kernel percentage, and good kernel quality. Compared with ‘Barcelona’, Oregon's leading cultivar, ‘Yamhill’ has smaller trees, slightly higher nut yield, twice the nut yield efficiency, and similar pellicle removal ratings. The kernel quality is suitable for use in chocolate products and baked goods and is competitive with imported Turkish kernels.
