Key challenges in breeding durable disease-resistant cereals: North America. In Achieving Durable Disease Resistance in Cereals. R. Oliver, ed. Burleigh-Dodds Science Publishing Ltd., Cambridge, UK. Book Chapter. 978-1-78676-601-4. Interpretive Summary: In this chapter, we first discuss the challenges of diverse climates, diseases, and market classes that face North American small-grain cereal breeders and producers. We focus briefly on challenges due to the system of cereal breeding in the U.S., and the changing disease priorities brought about by shifts in pathogen races and agricultural practices. The rest of the chapter covers the status and prospects of lasting resistance to the main pests that breeders are currently tackling on the continent: Fusarium head blight, rusts, powdery mildew, leaf blotches, viruses, Hessian fly, and bacterial disease. Technical Abstract: In this chapter, we first describe the challenges of diverse climates, diseases, and market classes that face North American small-grain cereal breeders and producers. We touch briefly on challenges inherent in the complex structure of cereal breeding on the continent, and the changing disease priorities brought about by shifting pathogen races and production practices. The remainder of the chapter is devoted in rough priority order to prospects for durable resistance to the main pests currently confronting the continent: Fusarium head blight, rusts, powdery mildew, leaf blotches, viruses, Hessian fly, and bacterial disease. |
