Hazelnut Pollinizer Cultivars: Gamma (OSU 589.028), Delta (OSU 510.041), Epsilon (OSU 669.073), Zeta (OSU 670.095)

Oregon State University released four new eastern filbert blight (EFB) resistant cultivars as pollinizers in January 2002. These cultivars provide pollinizer options for the midseason through very late season female flower bloom of 'Lewis', 'Clark', and other varieties. This publication outlines characteristics of each pollinizer cultivar, including incompatibility alleles, flowering and nut characteristics, and pest tolerance.
