During the 20th century, efforts were made to breed hazelnuts suited to eastern North American conditions. Breeding projects were aimed at producing northern hardy trees, large nuts, bud mite and eastern filbert blight resistance. Pioneering efforts were made by J.U. Gellatly of British Columbia, George Slate of Geneva N.Y. Experiment Station, Cecil Farris of Michigan, and Carl Weschcke, whose work was taken up by Phil Rutter of Wisconsin. The breeders crossed European bush and tree hazels with native hazels creating northern hardy selections, but with variable blight resistance. The University of Oregon at Corvallis, has recently produced more blight resistant selections. We use our orchards to screen cultivars and seedlings from these breeders along with our own for disease resistance. Our seedlings come from these selections now. We expect 70% of the seedlings to carry the blight resistance genes. We believe we have some nearly blight immune varieties as grafted and layered selections.The future looks bright for commercial hazelnuts in Southern Ontario, or anywhere in zones 5-7. We also buy hazels for cracking.
