Quinoa, buckwheat, and spelt are ancient grains that have been grown for thousands of years in their native regions. They have served well as highly nutritious staple food sources but have been largely neglected by research universities in the U.S., who typically favor the major cereal and legume crops. Each of these alternative grains is in high demand from consumers and would fill an underrepresented niche in our farming and marketing systems; however, there is currently very little known about locally adapted varieties for buckwheat, quinoa, and spelt. Farmers have requested that research be conducted with these grains in organic systems and to our knowledge, very little, if any, research has been done. This project was initiated from its onset by organic farmers and relies heavily on farmer participatory research for its success.
Buckwheat, quinoa, and spelt have the potential to: diversify cropping systems with underrepresented grain crops destined for local markets; function as valuable high-biomass cover crops; provide locally grown options for nutritious food for humans, particularly those with gluten intolerance or wheat allergies; and serve as a high protein, nutritious animal feed.
Intensive variety trials in these crops are being conducted with growers at eight locations across Washington state and North Dakota and multiple agronomic, nutritional and quality traits are being be evaluated for each crop. These ongoing trials (funded by WSU BIOAg program) will help identify the varieties with the traits deemed most necessary by farmers at each diverse location.
In the next step, we will utilize these varieties as parents in crossing schemes that will serve as the genetic basis of a heterogeneous population that is the foundation of the evolutionary participatory breeding (EPB) method. We will develop these populations in the fall and winter of 2010/2011 in WSU greenhouses and they will be planted in farmers' fields in 2011. From this point, we will follow the EPB method using a combination of farmer-based selection and natural selection to develop high quality populations for each crop that are adapted to the different environments across Washington state and North Dakota.
This project combines research with extension and education to address and improve innovation and diversification of farming systems to increase their resiliency and sustainability. Additionally, this project focuses on breeding within the larger context of organic, sustainable farming systems that increase local, diversified food access and nutrition.
