‘Sacajawea’ (OSU 540.130) was developed and evaluated at Oregon State University, Corvallis, Oregon, and was released in February 2006. Compared to ‘Barcelona,’ ‘Sacajawea’ is a slightly smaller tree but has a higher yield efficiency, a higher percent kernel, fewer kernel defects, and smaller nuts. Nuts mature and fall free of...
'Santiamʼ (OSU 509.064) was developed and evaluated at Oregon State
University, Corvallis, Oregon, and it was released in February 2005. This cultivar has complete resistance to eastern filbert blight (EFB) caused by Anisogramma anomala (Peck) E. Müller. Resistance is conferred by a single dominant gene from ʻGasaway.ʼ Compared to ʻBarcelona,...
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...
‘Lewis’ is a hazelnut cultivar developed by Oregon State University and released in January 1997. This cultivar is precocious, and it is more productive and has a smaller tree size than ‘Barcelona.’ Harvest is earlier than for ‘Barcelona,’ and the nuts have fewer defects.
