Scientists Find Aphid Resistance in Black Raspberry
November 7, 2012| |
USDA scientist Chad Finn and colleagues discovered that black raspberries have resistance to the large raspberry aphid. They screened seedling from several wild raspberry populations for aphid resistance and found that strong resistance is present in three populations coming from Ontario, Maine, and Michigan. The aphid resistance in Maine and Ontario seems to be controlled by several genes, while the resistance in Michigan is controlled by a single gene. Identification of these resistance genes will help scientists to incorporate aphid resistance into commercialized varieties of black raspberry.
