Graf, R. J., Beres, B. L., Laroche, A., Gaudet, D. A., Eudes, F., Pandeya, R. S., Badea, A. and Randhawa, H. S. 2013. Emerson hard red winter wheat. Can. J. Plant Sci. 93: 741-748. Emerson hard red winter wheat (Triticum aestivum L.), a cultivar developed using doubled haploid technology, was registered for western Canadian production in 2012. It is eligible for grades of the Canada Western Red Winter (CWRW) wheat market class. Evaluation across western Canada from 2008 to 2010 was relative to CDC Osprey, AC Bellatrix, Radiant, and CDC Buteo, the CWRW wheat checks in the Western Winter Wheat Cooperative Registration trials. Overall, Emerson had significantly lower grain yield than the mean of these checks; however, in the stem rust, leaf rust and fusarium head blight prone eastern prairies the grain yield of Emerson was not significantly different from CDC Buteo and CDC Falcon, which have been the predominant cultivars in this region. Emerson had good winter survival, intermediate maturity, medium height, strong straw, high test weight, and high grain protein concentration. It expressed improved resistance to fusarium head blight, stem rust, leaf rust, and stripe rust relative to the checks. End-use suitability analysis indicated that Emerson had strong dough rheology, and excellent milling and baking properties.
