The effect of powdery mildew (Blumeria graminis f. sp. tritici) on the grain yield and protein content of one susceptible, Springfield, and three moderately resistant cultivars, Fielder, AC Reed and AC Nanda, of soft white spring wheat (Triticum aestivum) was examined at two field locations near Lethbridge and Vauxhall, Alberta, in 1999 and 2000. At the start of heading, powdery mildew development was suppressed in half of the plots of each cultivar by a single spray application of the fungicide Tilt (propiconazole). Severe powdery mildew infection of the susceptible cultivar Springfield resulted in yield reductions ranging from 11.4 to 19.9%. The grain yield of the moderately resistant cultivar Fielder was significantly reduced at both sites in 1999 by 7.6–10.5% while AC Reed suffered a significant yield loss (7.6–9.1%) at Lethbridge in both years. The moderately resistant cultivar AC Nanda consistently had the lowest powdery mildew ratings and its yield was unaffected by the disease. A single fungicide application prevented disease buildup on the moderately resistant cultivars, but not on Springfield. The grain protein content of the moderately resistant cultivars was unaffected by powdery mildew, but it decreased in Springfield by 0.6–0.7%.

AC Wilmot is a spring feed wheat (Triticum aestivum L. em Thell.) with more grain yield than the check cultivars in Atlantic Canada. It is moderately resistant to powdery mildew. The reaction of AC Wilmot to leaf and glume blotch is similar to the check cultivars. AC Wilmot is slightly more susceptible to fusarium head blight than the check cultivars. AC Wilmot is suitable for production in Atlantic Canada. Key words: Triticum aestivum, wheat (spring), cultivar description

End Use

Sadash is a soft white spring wheat (Triticum aestivum L.) that meets the end-use quality specifications of the Canada Western Soft White Spring class. Sadash is well-adapted to the wheat-growing regions of southern Alberta and southern Saskatchewan. Based on data from the Western Soft White Spring Wheat Cooperative Registration Test from 2003 to 2005, Sadash exhibited high grain yield, mid-season maturity, semi-dwarf stature with very strong straw, and good resistance to shattering. Sadash expressed resistance to the prevalent races of stem rust and powdery mildew, intermediate resistance to loose smut, moderate susceptibility to leaf rust and common bunt, and susceptibility to Fusarium head blight. Based on end-use quality analysis performed at the Grain Research Laboratory of the Canadian Grain Commission, Sadash had improved test weight over the check cultivars AC Reed and AC Phil and similar milling and baking performance.Key words: Triticum aestivum L., cultivar description, wheat (soft white spring), grain yield, quality, disease resistance

Soft White Spring Wheat

Field experiments were conducted over four growing seasons in southern Alberta to develop improved irrigation and nitrogen fertilizer recommendations for soft white spring wheat (Triticum aestivum L.). Irrigation to provide available water in the root zone to maturity maintained acceptably low protein content of soft wheat fertilizer-N plus soil test NO3-N levels from 140 to 208 kg ha−1. Nitrogen fertilizer increased protein content in all 4 yr of the study and increased yields each year except 1981 when the soil contained a high level of NO3-N. The protein content was not raised above the level considered acceptable for the domestic Canadian market (10.5%, moist basis) unless fertilizer rates in excess of the economic optimum level were applied. Fertilizer-N response curves were developed for each cultivar, irrigation treatment, and year combination. These were used to show the relationship between yield and the level of fertilizer N plus soil NO3-N which would result in economic optimum yields of soft white spring wheat of acceptable protein content. The results suggest N rates can be increased about 30 kg ha−1 for each t ha−1 increase in the target yield of the producer.Key words: Wheat (soft white spring), Triticum aestivum L., irrigation, nitrogen fertilizer, protein, target yield
