Researchers and farmers have been trying to crossbreed these two species of hazelnuts for over 100 years, said Jason Fischbach, emerging crops outreach specialist with the University of Wisconsin-Madison Division of Extension. Since 2007, Fischbach has worked to develop a commercially viable version of this crop through the Upper Midwest Hazelnut Development Initiative. He partnered with farmers who grew the plant from seedlings to breed the best varieties.
