Agriculture Roundup for Friday February 17, 2023

Feb 17, 2023

The Western Grains Research Foundation has created a series of twelve regional factsheets that show the benefits of diversifying crop rotations.

The Resilient Rotations project is part of the Integrated Crop Agronomy Cluster (ICAC) that is evaluating various crop rotations to help create more productive, sustainable, and resilient cropping systems on the prairies.

The project is led by Dr. Kui Liu, a research scientist with Agriculture and Agri-Food Canada (AAFC).

“We are approaching crop rotation by looking at a systems approach – all the elements that impact crop rotation from soil health, economics and yield to local growing conditions,” Liu said. “It’s a more holistic way to look at crop rotation and one we hope will provide new insights and options for farmers in Western Canada in a more customized, prescriptive type of approach.”

Ask Canada’s most decorated soybean breeder his favourite part of the job and he doesn’t name a single variety. He names the students.

Istvan Rajcan is a professor of soybean breeding and genetics in the Department of Plant Agriculture at the University of Guelph, where he has run the soybean breeding program for 28 and a half years. In that time he has developed 87 soybean cultivars, published 140 refereed papers and trained 51 graduate students. In 2025 he received the Public Sector Impact Award from the National Association for Plant Breeding.

He is also worried. In this episode he says Canada is at a crossroads, pointing to recent government cuts to plant breeding programs and to the facilities that support them. His prescription is structural. "Plant breeding funding formula has to be a long-term one," he says.

The formula he is defending is the public-private matching arrangement his program runs on. Private seed companies fund the work, provincial or federal money matches it, and the combined pool stretches each dollar further than either source could alone. At the National Association for Plant Breeding annual meeting in June, he says American public breeders were often surprised at how well that collaboration works in Canada.

He also describes how the people entering plant breeding have changed. His early graduate students came mostly from farms. More recently they include, in his words, "city kids who just became excited about genetics."

Topics covered:

Why public-private plant breeding funding in Canada needs a long-term

commitment rather than a larger one

How matching private seed company investment with provincial and federal

dollars multiplies research capacity

How the graduate student pipeline into plant breeding has shifted from

farm kids to city kids
