For the past 35 years hulless barley development and breeding have been a significant segment of the Crop Development Centre, University of Saskatchewan, barley research and breeding program. Since the release of the first hulless feed variety, Scout, in 1982, program emphasis has shifted to hulless barley for food and malting/brewing. The high-performing, agronomically superior variety CDC McGwire released in 1999 set the stage for and provided the baseline for further hulless malting barley variety development. CDC ExPlus, with improved malting quality, was released in 2009. It has been followed by HB08304 (to be released in 2011), which demonstrates agronomic improvement versus the standard CDC McGwire and further malting/brewing quality advantage versus CDC ExPlus, having lower grain protein, lower malt β-glucan, and increased malt enzyme activity.

Brian Rossnagel has been a plant sciences professor and the barley and oat breeder for the Crop Development Centre at the University of Saskatchewan since 1977. Raised on a small mixed farm in central Manitoba, he earned a B.S. degree in agriculture (1973) and then a Ph.D. degree in plant breeding and agronomy (1978) at the University of Manitoba. Over his career, he has released more than 80 barley and oat varieties with a wide range of specific uses, from low-lignin, high-fat feed oats to two-row malting barley. Some additional keystones of his breeding and research career are the development of hulless barley for feed, food, and malting and consistent collaboration with other researchers, including cereal chemists, animal nutritionists, agronomists, plant biotechnologists, and plant pathologists. Having been conferred numerous honors and awards over the last few decades, his three most recent commendations (all in 2010) are the American Oat Workers Conference Distinguished Service to Oat Improvement Award, recognition as a University of Saskatchewan Distinguished Chair, and induction into the Saskatchewan Agriculture Hall of Fame.
