CPS Registers Multigenic Clubroot Resistant Canola Variety

Crop Production Services is releasing a canola variety it says offers the “first true” multigenic resistance to clubroot disease, including the new 5X pathotype found in Alberta.

The Proven Seed-brand variety PV 580 GC was formally registered on October 23.

“The CPS Canadian Research and Development team has invested heavily in discovering and breeding new hybrids that will provide canola growers with increased levels of clubroot resistance,” said Ryan McCann, Director – Seed, CPS Canada, in a news release on Tuesday. “Our hybrid program includes incorporation and testing of novel genes that offer a high level of resistance to multiple clubroot pathotypes. We consistently focus on delivering increased yield and yield stability through disease resistance.”

The company says the Genuity Roundup Ready hybrid has high levels of resistance (through more than one gene) to the current predominant clubroot pathotypes, as well as some of the new clubroot pathotypes referred to as 5X.

“PV 580 GC…will be initially available to growers in regions at higher risk of clubroot. We successfully tested hybrids against pathotype 5X this summer,” added Jamie Mills, Canola Product Line Manager, CPS Canada.

CPS has been working with the University of Alberta and Agriculture and Agri-Food Canada, providing source material from the company’s germplasm.

“CPS initiated this collaboration with the U of A in 2012, and one of the objectives was to deliver CR-resistant genes to the market in competitive canola hybrids. We’re very pleased with the progress that’s been made and farmers will benefit from the good work that’s been done,” said Habibur Rahman, professor of canola breeding the U of A.

Earlier this year Canterra Seeds released CS2000, the first canola variety billed to have “intermediate” resistance to the new 5X pathotype.
