Thomas, J. B. and Graf, R. J. 2012. AC Readymade and AC Tempest, selections from Redwin hard red winter wheat. Can. J. Plant Sci. 92: 355-361. AC Readymade and AC Tempest are hard red winter wheat (Triticum aestivum L.) cultivars selected from the Montana cultivar ‘Redwin’ to conform to the kernel visual distinguishability requirements of the Canada Western Red Winter (CWRW) wheat class. AC Readymade and AC Tempest were registered in 1991 and 1999, respectively, following 3 yr of testing in the Western Winter Wheat Cooperative registration trials relative to various checks including Winalta, Norstar, CDC Clair and CDC Osprey. The survival characteristics of these cultivars demonstrated that they were well-suited to the relatively mild winter climate of southern Alberta. In this region of the prairies, AC Tempest had 4% higher grain yield than AC Readymade and was not significantly different from the other checks except Winalta, which was lower yielding. Both cultivars displayed relatively late maturity, moderate height, exceptional straw strength, high test weight, large kernels, high grain protein content and moderate resistance to common bunt. AC Tempest had significantly higher flour yield than AC Readymade.
