Genomic strategies to improve field survival of winter cereals and stabilize yield

Wheat is a major Canadian crop with average annual production of 25-30 million metric tons and accounts for about $5 billion in export revenue. The three Prairie Provinces account for 84% of the Canadian arable land and are primary producers of wheat. Spring wheat (~ 93%) is the dominant type grown in Canada. However, in years with low winter kill winter wheat produces 20-40 % higher yields than spring types. The very harsh prairie winters with temperatures dipping to below -40oC and a short growing season which limits the spring seeded crops that can be grown to maturity. Improving low temperature tolerance in general and winter field survival in winter crops is urgently needed to keep the Canadian producers sustainable, competitive and meet the requirements of growing global population.
