New Winter Canola Variety Released by K-State

MANHATTAN, KAN. – A new winter canola variety, Riley, has been released by the Kansas Agricultural Experiment Station. Foundation and certified seed of Riley will be available for distribution on a widespread basis in fall 2011, according to Mike Stamm, canola breeder for Kansas State and Oklahoma State universities.

Riley has consistently been one of the highest yielding open-pollinated varieties grown in regional 2008-2010 canola variety trials, Stamm said.

“Riley appears very well-adapted to the central Great Plains and High Plains, and it has competed favorably with other adapted varieties grown in both high-yielding and stressed environments,” he said

In comparison to Wichita, a popular winter canola variety, Riley also has averaged 2.8 percent greater oil content in Kansas trials.

Winter survival of Riley is equivalent to that of competing varieties, Stamm said. On average, Riley reaches 50 percent bloom the same day as and maturity about a day later than Wichita. In addition, it is approximately the same height.

“Overall, Riley appears to have broad adaptation and can yield favorably wherever winter canola is grown. Riley represents the first release opportunity from the canola breeding program, demonstrating progress beyond that of Wichita,” the canola breeder said. “Riley is disease-tolerant and has an attractive, high-quality fatty acid profile.”

Stamm added, “With high-quality, certified seed, new open-pollinated varieties such as Riley provide value in a region where canola is gaining a foothold.”


K-State Research and Extension is a short name for the Kansas State University Agricultural Experiment Station and Cooperative Extension Service, a program designed to generate and distribute useful knowledge for the well-being of Kansans. Supported by county, state, federal and private funds, the program has county Extension offices, experiment fields, area Extension offices and regional research centers statewide. Its headquarters is on the K-State campus, Manhattan.
