How to protect clubroot resistance

Clubroot is a soil-borne disease caused by Plasmodiophora brassicae. It’s an emerging threat to canola production. Results of this study show that effective clubroot management relies on cultivar resistance in combination with management practices that reduce viable resting spore populations. lubroot is a soil-borne disease caused by Plasmodiophora brassicae. It’s an emerging threat to canola...

Shift in flea beetle species composition

Key practice: Crucifer and striped flea beetles react differently to their environment and to seed treatments. It is important to monitor emerging canola seedlings to know what you’re up against. Project title, Lead researcher: “Potential flea beetles species composition shift in Prairie canola,” 2007-12, Juliana Soroka, Agriculture and Agri-Food Canada (AAFC) Saskatoon Grower organization funder:...

Reseed when fewer than two plants per square foot

While hybrid canola has a high degree of phenotypic plasticity that allows it to compensate for low plant populations, growers need to know when the population is likely too low to compensate for the reduced plant stand. Reseeding is more likely to provide an economic benefit when: the population is below 20 plants per square...

Mapping a route to clubroot resistance

Twelve molecular markers were identified that will be useful in breeding programs including gene pyramiding for durable clubroot resistance.
Key practice: P. brassicae can rapidly adapt to the selection pressure provided by currently available clubroot-resistant canola varieties. For durable clubroot resistance, it will be important to stack resistance genes and rotate them in clubroot-infested fields. Project title, Lead researcher: “Studies on the genetic and molecular basis for clubroot resistance in canola,” 2010-15, Stephen Strelkov,...

Straight combining: environment and timeliness matter more than variety

Key practice: This study found that most hybrids could be straight combined successfully with minimal harvest losses when harvested in a timely manner under reasonably average environmental conditions. When making a seed decision, balance pod shatter resistance with other selection factors including yield potential, herbicide system, days to maturity and other agronomic factors. Project title,...
