Winter Wheat Variety Trial Thanks to the Alberta Winter Wheat Producers Commission for their support of this project. Summary: A trial was initiated in 2010/2011 to evaluate the performance and potential of winter wheat varieties in the brown soil zone. Eighteen varieties of winter wheat were seeded at a site near Oyen under the direction of Rob Graf of Agriculture Canada and funded by the Alberta Winter Wheat Producers Commission. The site was seeded on September 8, 2010 into firm soil. Emergence was very good. Past Results: Cumulative yield from the years 2003-2011 is reported in the table below, combining the results between past years at Acadia Valley and this year at Oyen. More information on varieties is available in the variety guide in the seed.ab.ca seed guide or website or on the Alberta Agriculture and Rural Development website at www.agric.gov.ab.ca. The check has changed to CDC OSPREY. Seven varieties have yielded as well as, or better than the check. They are AC Bellatrix, CDC CLAIR, Radiant, Peregrine, CDC Ptarmigan, CDC Kestrel and CDC Harrier. A visual survey of sawfly cutting in the winter wheat variety trials in 2004 and 2005 has shown that there is less sawfly damage in the Radiant plots. Cooperators:
