I lead the specialty crop breeding and agronomy program at WSU. Our goal is to increase the genetic- and bio-diversity of cropping systems across Washington State through the development of new cultivars and implementation of ecologically-rooted production practices. Internationally, we conduct participatory breeding and agronomic research on quinoa, barley, and millets in Rwanda, Malawi, and Ecuador. Our group focuses on breeding and/or cropping systems research in barley, quinoa, spelt, buckwheat, perennial grains, industrial hemp, millets, and grain amaranth. We emphasize crops, varieties, and/or farming systems that optimize nutritional value and provide tolerance to heat, drought, and diseases while improving yield, flavor and end-use quality. Our cropping systems research has included studies on intercropping, cover crops, crop rotation effects, no-till farming, crop-livestock integration, and optimal planting dates and nitrogen, irrigation and seeding rates.

Quinoa: Improvement and Sustainable Production
Kevin Murphy (Editor), Janet Matanguihan (Editor)
Quinoa is an ancient grain that has grown in popularity in recent years. It has been known as a good source of both protein and fiber. As the demand for quinoa increases a comprehensive and up-to-date reference on the biology and production of the crop is essential. Quinoa: Improvement and Sustainable Production brings together authors from around the world to provide a complete assessment of the current state of global quinoa research and production. Topics covered include quinoa history and culture, genomics and breeding, agronomy, nutrition, marketing, and end-uses. The book focuses in particular on the emerging role of quinoa in providing increased food security to smallholder farmers and communities throughout the world.
Quinoa will interest quinoa researchers, producers, crop scientists, agronomists, and plant geneticists, as well as advanced students working with this important grain.
This week, a new food is appearing on Passover tables around the country. The Orthodox Union, the authority on kosher foods, recently ruled that certain brands of quinoa could carry its “Kosher for Passover” symbol.

Can Quinoa Farming Go Global Without Leaving Andeans Behind?
Will Quinoa be the new corn . . . that might be a stretch . . .
MOUNT VERNON, Wash. – After more than 22 years of breeding wheat for Washington State University, Steve Lyon never expected to make a name for himself in the barley field. But this spring’s release of ‘Lyon,’ a new variety of barley, is one way his colleagues in Pullman have chosen to recognize his long-term contributions to small grains research.
“As a graduate student in Stephen Jones’ winter wheat program, I worked with Steve Lyon on a daily basis,” said WSU barley breeder Kevin Murphy.
PULLMAN, Wash.–Every week, Kevin Murphy gets e-mails from farmers interested in growing quinoa.
There isn’t enough seed available, so Murphy intends to grow more of the popular specialty crop next spring on a half-dozen farms in Washington and Oregon.
Quinoa will never rival wheat’s overall popularity, Murphy said, but it has the potential to become an important specialty crop for the Northwest.
New WSU feed barley has disease resistance package (Muir)
Washington barley growers will have another new variety to consider next spring.
Muir is a spring, two-row feed barley developed by Washington State University barley breeder Kevin Murphy in Pullman, Washington.
This WSU breeding team’s pursuit of a wheat variety that sprouts year – after – year instead of dying after producing seed was featured in the science section of the New York Times.
