The Hybrid Hazelnut Consortium

Buy Hazelnut Trees

Creating a research and breeding program to develop hazelnuts as a widely adapted, high-yielding, and low-input sustainable crop that is competitive for food, feed, or bioenergy.

The consortium is comprised of four organizations dedicated to this goal: the Arbor Day Foundation, Oregon State University, Rutgers University, and the Nebraska Forest Service/University of Nebraska-Lincoln. The consortium has received $3.1 million from the USDA to continue its work on developing next-generation hybrids that can expand commercial hazelnut production in the U.S.

Nutrition

A Leader in Nutritional Qualities

Experts agree that hazelnuts are packed with vitamins, protein, and good fats, earning them the FDA heart healthy seal of approval. Hazelnuts rank at or near the top of many of the important health categories. Hazelnuts are a rich source of protein, vitamin E, folate, B vitamins, and arginine. Hazelnut cooking oil has a similar composition to extra virgin olive oil with high content in Omega 9 and Omega 6 fatty acid. This makes hazelnuts another healthy cooking oil option with flavorful taste. Hazelnuts have not yet reached their full potential in the United States. With much wider sustainable production, they could be a main component of a healthy diet.

Environmental & Agricultural Benefits

Drought Resistance: Perennial plants' deep roots resist short-term droughts, unlike annual crops.
Carbon Sequestration: Hazelnuts absorb more carbon than annual crops, aiding in carbon sequestration.
Soil Erosion: Hazelnuts reduce erosion with minimal tillage and extended soil coverage as riparian buffer zone species.
Nitrogen Leaching: Their active perennial roots minimize nitrogen leaching year-round.
Land Diversification: Hazelnuts thrive on marginal soils and slopes, diversifying land use sustainably.

Sustainable Energy from Hazelnut Oil

Hazelnut oil is a largely unexplored, yet promising resource. Preliminary data reveals that opportunities exist to expand new markets for hazelnuts, such as for feed and biodiesel. Utilizing previous funding, the Hybrid Hazelnut Consortium has led the way in hazelnut oil research by investigating and enhancing the quantity of oil from hybrid hazelnuts while examining the properties of oil for both food oil and biofuel applications.

Wildlife Benefits from Hazelnuts Too

Hazelnut plants can provide great wildlife habitat and nutrition. In addition to the environmental benefits of hazelnuts, these bushes make attractive CRP plants, windbreaks, hedges, or riparian buffers.

Known wildlife that benefits from hazelnut plants include:

Birds: Quail, Ruffed Grouse, Wild Turkey, Pheasants, Woodpeckers, Blue Jays
Rodents: Squirrels, Chipmunks, Mice
Large Animals: Ground Hogs, Deer

Hazelnuts as Animal Feed

Feedstock is a largely unexplored, yet promising, opportunity for hazelnuts. The high protein content in native hazelnuts already makes them an attractive wildlife and livestock feed.

Through the Consortium’s breeding process, we hope to increase the amount of protein that can be grown per acre. In addition, the adoption of hazelnuts as a widely grown feedstock crop would increase overall crop diversity, which reduces producer risk and promotes more integrated, environmentally friendly production systems.

The Arbor Day Foundation's Role in the Hazelnut Consortium

The Arbor Day Foundation began the Hazelnut Research Project in 1996 with plantings of hybrid hazelnuts at Arbor Day Farm. By 2000 the project evolved to include charter members across the nation conducting research on hazelnuts in their own backyards and has nearly reached 100,000 active members. Key findings include:

Best Practices and methods for growing hazelnuts from seeds.
Hybrids Hazelnuts can thrive in Nebraska, among other states, as a dryland crop.
Arbor Day Farm Hybrids grow best in zones 4 to 8.

The Expansion of Hybrid Hazelnuts

The primary goal of the Hybrid Hazelnut Consortium is to significantly expand the commercial production region of hazelnuts in the United States and Canada. This goal can be met by focusing research and breeding efforts on developing productive hazelnut plants that express durable resistance to the disease Eastern Filbert Blight (EFB) while also enhancing cold hardiness and drought tolerance.

1996: A new orchard at Arbor Day Farm

In cooperation with Philip Rutter, a pioneer in hazelnut research and founder of Badgersett Research Corporation, 5,200 hazelnut bushes representing 60 promising hybrids replaced a cherry orchard and covered the slope behind Lied Lodge at Arbor Day Farm. In the following years, members received nuts from the orchard for planting in all kinds of conditions throughout the United States.

2005: More than 50,000 charter patrons assist the research

By 2005, the benefits of hazelnuts had touched the lives of 50,930 members who agreed to plant, observe, and report results. In return, participants received an annual report and Home Harvest Guide. On farms, in small towns, and in city suburbs, members found that participation was not only helpful, but interesting and fun. In some instances, it has also been financially rewarding—with crops available to sell or help feed the family.

2009: Hazelnut Consortium formed

Research scientists at the University of Nebraska–Lincoln, Rutgers University, and Oregon State University joined with Foundation staff to form the Hybrid Hazelnut Consortium. This expansion of expertise provided better opportunities to analyze reports from members, screen for the best bushes, and reproduce progeny through state-of-the-art laboratory and nursery techniques.

2012: Best progeny planted

Using nuts from the best of the original plants returned by patrons, along with promising bushes discovered growing in the wild, new seedlings were propagated and planted in the orchard at Arbor Day Farm. This introduction into the orchard not only provided nuts for further distribution and testing, but provided additional diversity that should lead to even better hybrids in the future.

2016: Consortium receives grant

The Hybrid Hazelnut Consortium secured a 5-year grant totaling $3.1 million from the USDA to continue its work on developing a next-generation hybrid that can expand commercial hazelnut production in the U.S. This funding was made available due to the progress the consortium has made so far—with critical support from Hazelnut Project Charter Patrons who have planted hybrid hazelnuts and reported their results.

Beaked

American

European

Beaked Hazelnuts have mature involucres that are 4 to 7 cm, twigs glandless, and prickly hairs on the involucres. Besides having small, thick-shelled nuts, native hazelnuts express a wide range of adaptability and a high resistance to EFB.

How to Find Hazelnuts

Native American Hazelnuts are found in the midwestern, eastern, and southeastern regions of the United States and in Canada. Please refer to the map to discover if you might have American hazelnuts growing in your state. The Consortium is primarily seeking samples from Alabama, Arkansas, Kentucky, Missouri, North and South Carolina, and Tennessee, especially in higher elevations in these states.
