Farmers are on the front lines of climate change. Droughts, heat waves, and erratic weather patterns aren’t just inconvenient—they’re existential threats to harvests and livelihoods. To stay ahead of these challenges, Agriculture and Agri-Food Canada (AAFC) scientists are reimagining what staple crops like wheat and oats can do.

Their playbook blends cutting-edge genomics, bioinformatics, and precision breeding with decades of conventional expertise. The goal: deliver faster, smarter, and more resilient varieties that thrive in Canada’s diverse climates while meeting the demands of global markets.

This isn’t a slow academic exercise. It’s a full-scale innovation push, where genetic insights translate into tangible gains for farmers planning the next season under increasingly unpredictable conditions.

Beating the Heat: Engineering Drought-Resilient Wheat

In Lethbridge, Alberta, AAFC researchers are probing one of wheat’s most important genetic levers: circadian clock genes. These genes control how plants grow, flower, and ultimately survive stress. By exploring subtle mutations in these natural regulators, Dr. John Laurie’s team identified a breakthrough variant of the long-studied Ppd-1 gene.

The result? Wheat lines that show significantly higher drought tolerance in controlled tests. Rather than waiting for nature to take its course, scientists are accelerating a natural adaptation process—delivering resilience years, even decades, sooner than conventional breeding alone could achieve.

The implications are profound. As dry seasons become more common, these insights could reshape how Canadian farmers manage risk, ensuring breadbaskets remain productive under harsher climates.

Wheat Varieties Built for Tomorrow’s Climate

Alongside genetic research, AAFC breeders are also rolling out new commercial-ready wheat varieties designed to perform under pressure:

  • AAC Raymond (Soft White Spring Wheat): Proven yield gains of 10–12% in hot, dry conditions, plus strong resistance to stripe and leaf rust.
  • DT 2046 (Durum Wheat): Combines Fusarium Head Blight resistance, heat and drought tolerance, and straw strength to withstand unpredictable storms.
  • AAC Rivers VB & AAC Ahead VB (Western Red Spring Wheat): Both outperform the popular AAC Brandon, bringing higher yields, midge resistance, and improved tolerance to Fusarium.

Together, these varieties reflect a broader strategy: stack traits for drought, disease, and yield to create plants that can survive volatility without sacrificing profitability.

The Oat Genome Revolution

If wheat is Canada’s breadwinner, oats are its sleeper star—powering everything from livestock feed to the oat milk boom. And here, genomics is rewriting the rulebook.

Led by researchers across Eastern and Western Canada, the oat program has fused traditional breeding with high-powered genetic modeling. The turning point came in 2013 with the launch of the ENCORE test, a nationwide system that evaluates thousands of oat lines every year. Since then, expanded genotyping and phenotyping have supercharged progress.

By 2018, breeders began deploying genomic selection—a method that predicts plant performance before field trials even start. This shift means over 6,000 oat lines can be screened annually, with the best candidates advanced faster and more confidently.

The payoff: accelerated development of oat varieties tailored to specific regions, higher yields, and improved nutritional qualities like beta-glucan content. In a crop that once advanced at a crawl, genomic selection is now the accelerator pedal.

Why It Matters

Climate volatility demands speed and precision from agriculture’s innovation engine. What AAFC is building is more than just new varieties—it’s a framework for resilience. By integrating genomics with boots-on-the-ground breeding, Canada is positioning itself as a leader in climate-smart agriculture.

For farmers, the benefit is simple but powerful: confidence. The knowledge that the seeds they put in the ground are not just products of yesterday’s research, but blueprints for tomorrow’s realities.
