Canadian breeders developed Colorado potato beetle resistant varieties – after 30 years of trials

 A Colorado potato beetle feeds on potato leaves. (Agriculture and Agri-Food Canada photo) It’s taken almost 30 years, but Agriculture and Agri-Food Canada (AAFC) scientists have finally won a monumental battle against the Colorado potato beetle (CPB). Dr. Benoit Bizimungu and Agnes Murphy, potato breeding research scientists at the Fredericton Research and Development Centre, recently developed two selections that are resistant to the major insect pest. Both varieties are available for industry to use in other trials as part of an accelerated potato variety release program. The new resistant varieties were developed as a team effort. Research scientist Dr. Helen Tai is part of the team. While she played an important role in the process, Tai said, “I stand on the shoulder of giants.” Tai stressed that traditional methods were used in all the breeding programs. “There are no GMOs (genetically modified organisms) in the potato breeding program at AAFC,” Tai says. She said the new varieties can be used in conjunction with integrated pest management.
