Canola program stacks genes against new clubroot
Rather than send out a canola variety with a single source of resistance against clubroot — especially the disease’s most recent pathotype — Agrium’s CPS division has stacked several sources into the new hybrids it’s sending for testing this summer. Crop Production Services on Monday announced its “next generation” of Argentine canola hybrids shows “high […] Read more
Clubroots beating all resistant canolas across Alta.
A study of 27 canola fields across Alberta has found 16 infected with clubroot pathotypes able to cause “high levels” of the disease — in canola plants with clubroot-resistant genetics. What’s more, the clubroot pathogen isolated from “many” of the infected fields in the study was virulent on all clubroot-resistant canola cultivars, the Canola Council of Canada […] Read more
Against clubroot, ‘I’-rated canola sits between ‘R’ and ‘S’
A new canola variety billed with “intermediate” reaction against a new pathotype of clubroot is being placed in the zone between “resistant” and “susceptible.” Canterra Seeds, the Winnipeg firm marketing the new CS2000 hybrid variety, clarified its claim for the seed in a statement on a company blog Wednesday, granting many growers may be seeing the […] Read more
Canola variety’s clubroot claim taken with caution
A new variety of canola with “intermediate” resistance to a new type of clubroot may be cause for optimism, but Alberta’s canola grower group says farmers need to know more before they buy. The Alberta Canola Producers Commission (ACPC) warned Monday that growers will need more specifics about claims that a new canola variety has […] Read more
Manitoba canola pest lab backed for equipment, research
A new Manitoba lab with federal, provincial and canola industry backing has been opened with the goal of staying a step ahead of canola diseases such as clubroot and verticillium wilt. The federal and Manitoba governments on Thursday announced $969,000 for equipment, including a polymerase chain reaction (qPCR) machine, and $250,000 for research at the […] Read more
