Dr. Brent McCallum

Dr. McCallum

Dr. Brent McCallum is a research scientist with Agriculture and Agri-Food Canada working at the Morden Research and Development Centre in Morden Manitoba. He received his Ph.D in Plant Pathology from the University of Minnesota in 1995 and started working at AAFC in 1996. His research focus is on wheat leaf rust disease in Canada. He conducts an annual national virulence survey in Canada to track changes in the pathogen population that could affect the wheat crop in Canada. He is involved in identifying and developing sources of resistance to use in future wheat cultivars and to understand the genetics of disease resistance. This includes mapping and marker development for genes of interest, host-parasite interactions, and understanding interactions between resistance genes. He is also involved in research projects on the causal rust, Puccinia triticina, to understand its pathogenesis, diversity and evolution.
