Variety is the spice of life—especially when it comes to food. When we think of food crops, we usually think of the basics: wheat, corn, soy, potato, and vegetable crops. These staple foods help sustain us for needed calories and nutrition. But, what about the challenges of food crops that add a little extra flavor to our diet? The June 22nd Sustainable, Secure Food blog explores the challenges in breeding hazelnut, hops, and mint with guest bloggers from Oregon State University.

On their own, hazelnuts are delicious, and their fatty acid profile is identical to olive oil. Healthy snacks, here we come!

According to Shawn Mehlenbacher, Oregon State University’s hazelnut breeding project is “developing new cultivars resistant to eastern filbert blight. This disease is caused by the fungus Anisogramma anomalaaccidentally introduced from the eastern United States. We are also looking for new cultivars that can resist insect pests, like filbertworm, brown marmorated stink bug, and Pacific flatheaded borer...The Willamette Valley is well-suited to hazelnut production. Acreage devoted to growing hazelnuts Oregon has expanded from 29,000 to 65,000 in the past decade. By creating hybrids between the European and American species, we hope to expand the areas suitable for hazelnut production.”


Craft brewing fans are also fans of hops—the crop that gives bitterness, flavor, and aroma to beer.  

“On the fun side of breeding challenges, breeders are working to develop new types of aroma hops—the types that add rich flavors to beers,” says Shaun Townsend. “These types of hops are dominating the market, and breeders are looking for new sources of flavor and aroma. Hop breeders are identifying and incorporating new disease and pest resistant genes into hop, and with aroma hops dominating the market, new sources of flavor and aroma are being sought. Beer is an important beverage for many cultures, and hops will continue to be in demand as one of the key ingredients in beer production.”


Ah, fresh breath. Many of us can thank the mint oil in our toothpaste for that. “Distilled mint oil is used not only in toothpaste, but in a wide variety of consumer products, candies and medicines,” says Kelly Vining. “The fungal disease Verticillium wilt has been the biggest challenge to mint production in the Pacific Northwest for decades…The wild relatives of cultivated mint may have genes responsible for conferring the wilt resistance trait. Introducing a new cultivar with fungal resistance will help create a more sustainable mint industry.”
