Canola varieties show genetic resistance to verticillium

Aug 09, 2023

Research in Manitoba has found some canola varieties, or canola lines in the development pipeline, have resistance to verticillium.

That’s a relief for canola growers because verticillium stripe has become a common disease in canola fields, at least in the eastern Prairies.

“I don’t know if they’re commercial (varieties) or not. The companies do not share that information with me,” said Dilantha Fernando, a University of Manitoba plant pathologist, who has been leading a project to understand genetic resistance to the soil-borne disease.

“They could be in the pipeline. They could be elite material. That part I don’t know. (But) this is good news for the (canola) industry.”

Video: Dr. Emerson Nafziger: Nitrogen Fertilizer Rates for Corn

The Crop Science Podcast Show, Dr. Emerson Nafziger from the University of Illinois breaks down decades of nitrogen research. From the evolution of N rate guidelines to how soil health and hybrid genetics influence nitrogen use efficiency, this conversation unpacks the science behind smarter fertilization. Improving how we set nitrogen fertilizer rates for rainfed corn is a key focus. Discover why the MRTN model matters more than ever, and how shifting mindsets and better data can boost yields and environmental outcomes. Tune in now on all major platforms!

"The nitrogen that comes from soil mineralization is the first nitrogen the plant sees, and its role is underestimated."

Meet the guest:

Dr. Emerson Nafziger is Professor Emeritus of Crop Sciences at the University of Illinois at Urbana-Champaign, with degrees in agronomy from Ohio State, Purdue, and Illinois. His research has focused on nitrogen rate strategies and crop productivity. He co-developed the Maximum Return to Nitrogen (MRTN) model, which is widely used across the Midwest. His research spans N response trials, hybrid interactions, crop rotation effects, and yield stability.
