Wild potatoes from Germany breed stronger, more disease resistant potatoes in Canada

Wild potatoes acquired from a gene bank in Germany six years ago are producing promising results for Agriculture and Agri-Food Canada researchers trying to develop superior Canadian varieties with resistance to some of the most problematic potato diseases. Stronger potato varieties will increase yields for Canadian growers, which translates into higher profits. Dr. Benoit Bizimungu, head of potato breeding at the Fredericton Research and Development Centre, said a number of hybrids bred from these wild varieties could be ready for industry trials next year. Bizimungu selected the German plants because of superior traits such as high yield, as well as strong natural resistance to PVY, late blight, drought, and insects like the Colorado potato beetle. “Although the primary interest was multiple disease resistance and high yield potential, a number of progenies show a nice deep yellow flesh color, which is usually associated with carotenoids,” says Bizimungu. More
