Brent McCallum
I am a plant pathologist specializing in wheat leaf rust disease. My research is focussed on developing genetic resistance to leaf rust and working with plant breeders and geneticists to incorporate this resistance into Canadian wheat cultivars. My program is very collaborative with colleagues in many different research areas and at various research institutions across Canada and the world.
Current research and/or projects
Various research projects focussed on the genetics of wheat leaf rust resistance. This includes discovery of resistance, determination of the genetics of resistance, fine mapping resistance genes, marker development and gene cloning. I also research the causal organism Puccinia triticina conducting an annual virulence survey of the pathogen and other genetic research on this pathogen.
Research and/or project statements
- Genetics of wheat leaf rust resistance.
