  • artificial intelligence in grain quality
  • cereal chemistry
  • registration tests

Current Projects:

  • Develop agronomically superior hard red winter wheat cultivars with enhanced disease and pest resistance for the brown soil agri-climatic zones of the western prairies, which requires resistance to the wheat curl mite, common bunt and the Russian wheat aphid
  • Develop agronomically superior hard red winter wheat cultivars with enhanced disease resistance for eastern Canada and the black soil agri-climatic zones of the Prairies, which require resistance to stem rust, wheat curl mite, leaf rust, fusarium head blight
  • Develop agronomically superior soft white and soft red winter wheat (pastry) cultivars with Fusarium Head Blight (FHB) resistance/tolerance to protect and enhance end-use product quality and safety in Ontario, Quebec and Atlantic Canada.
  • Develop and release improved (yield, quality, adaptability, and/or disease resistance) cultivars and breeding lines of soybeans
  • Develop distinguishable, super high yielding winter wheat cultivars with excellent agronomic and disease resistance characteristics for use in the bio-based fuel and livestock industries
  • Develop germplasm that incorporates important characteristics (e.g.: improved or diversified resistance/tolerance to biotic and abiotic stresses such as Fusarium head blight, dwarf and common bunt, stem and leaf rust, snow mold, wheat curl mite)
  • Develop hard red winter wheat cultivars (combining superior yield, agronomic characteristics and disease/pest resistance) with end-use quality characteristics comparable to Canada Western Red Spring (CWRS) wheat for the various agri-ecological productions
  • Develop hard white winter wheat cultivars for the various agri-ecological production zones of Canada, with superior agronomic traits, appropriate disease/pest resistance and processing/utilization quality for domestic and export markets
  • Develop soft white and soft red winter wheat (pastry) cultivars/germplasm with Fusarium head blight resistance to enhance and protect grain quality and food safety
  • Develop technologies and enhanced ability to quantify quality attributes of soybeans and soy products and determine how various soybean traits affect the yield and quality of soy products
  • Development of high yielding disease resistant and winter hardy wheat cultivars
  • Development of high yielding superior quality soft white winter and hard winter wheat cultivars with fusarium head blight
  • Fusarium resistance breeding
  • Improved food safety and sustainability through the development of winter wheat with improved disease resistance and diversified end use quality attributes
  • Wheat variety development funded by the WGRF Wheat Check-off
