Summary

‘Clark’ is a hazelnut selection developed by Oregon State University. Trees of this genotype are about 30 percent smaller than ‘Barcelona’ yet have comparable yields to ‘Barcelona.' This selection has good quantitative resistance to eastern filbert blight (EFB). Harvest is 7–10 days earlier than ‘Barcelona’ and nuts are free-husking. Nuts have a high percent kernel, and kernels blanch well.
