  • Spring and winter canola breeding for Ontario, western Canada and Europe using doubled haploid methodology.
  • In vitro selection of various traits including, disease resistance, frost hardiness and oil quality improvements (eg. reduced glucosinolates, reduced saturates) in canola.
  • Pest resistance sourced from wide crosses with weedy relatives, including cabbage seedpod weevil resistance, root maggot resistance and flea beetle resistance.
  • Development of an efficient microspore culture system in corn (Zea mays) for in vitro selection for disease resistance.
  • Breeding of root maggot (Delia sp.) resistant rutabaga germplasm.
  • Development of a universal microspore culture system for production of doubled haploids in cereals (barley and wheat)
  • High antioxidant (rosmarinic acid) production in Mentha spicata (spearmint) for the nutraceutical and functional food industry.
