Abstract excerpt

Crown rust, caused by the fungal pathogen Puccinia coronata f. sp. avenae (Pca), is a destructive foliar disease of oat. Use of host resistance is the preferred method of disease management. However, frequent emergence of new Pca races has hindered crown rust management in oat. Identification and deployment of non-race-specific genetic resistance will aid oat breeding efforts to develop germplasm with durable...
