Breeding for Resistance to Leaf Blotch Pathogens in Saskatchewan Oat

Over the four years (2014-2017) that field surveys were conducted in commercial oat fields to evaluate the prevalence of oat leaf blotch pathogens P. avenae was the most often identified, being present in 59% of the 160 fields surveyed. Cochliobolus sativus was present in 23% of surveyed fields while S. avenae was only identified in 3% of fields. The ranking prevalence of these pathogens was consistent across all four years and differs from prior surveys conducted where S. avenae was observed in all years and with greater prevalence than C. sativus in most years (2011-2013).
