4DWheat: diversity, domestication, discovery, delivery

 

Funding period: 2019-2023
Lead: Sylvie Cloutier
Total GRDI funding: $2,805,423

Wheat (Triticum spp.) is the most important crop for current and future global food security. Canada is a major supplier of wheat globally, and supports a Canadian agri-food industry of >$6 billion annually. Wheat improvement programs across the country are working to develop new wheat cultivars that can tolerate our hot and dry environments, are resilient to often erratic weather extremes, and are resistant to emerging diseases. 4DWheat will apply the very latest in genomic strategies to focus on two major challenges: enhancing yield and managing producer risk to important diseases. One strategy is to utilize genetic diversity lost from breeding since wheat was domesticated more than 10,000 years ago to fully capture diversity in wheat breeding.
