One step closer to sclerotinia control

Science Edition 2016—Key result: Sclerotinia stem rot-tolerant varieties are available and efforts continue to improve varietal resistance, in both the public and private sectors. Researchers on this project have identified previously undiscovered genes associated with the plant defense response, providing valuable resources for researchers interested in developing sclerotinia-resistant canola lines. Project title, Principal investigators: “Getting one step...

Ideal seeding speed depends on drill, conditions

Science Edition 2016—

An even seeding depth across all rows will improve canola uniformity and seed survival, but the seeding speed to achieve this consistency will depend on the drill, soil type and field conditions. It helps to run your own tests.

Annual soil tests improve nitrogen returns

Science Edition 2015—Key practice: Predicting how much nitrogen is reserved in the soil is difficult. Given its high cost in canola production, conducting an annual soil test on each field to determine appropriate rates is a good idea. The wild card is moisture supply throughout the growing season. Project title, Lead Researcher: “Long-term effects of different soil...

Understanding the cellular mechanisms of clubroot disease and developing a new form of clubroot resistance

Science Edition 2015—Key practice: Rather than using genetically resistant varieties or the application of soil amendments and fungicides, this study is working to develop a new, alternative approach to clubroot resistance by silencing pathogen gene expression within the plant itself. Project title, Lead researcher: “Genomics of Clubroot disease development in canola and development of in-plant RNAi to...

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.
Science Edition 2015—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,...
