Research Category: Soybean Disease and Insect Control Year: 2002 Researcher: Terry Anderson Institution: AAFC Topic: Biology and control of important diseases of soybeans in Ontario Funding: $20,000 Research Details: The objectives of this research were to understand and develop resistance to disease for soybeans. All areas of the project were completed as scheduled. Isolates of Phytophthora will be useful in confirming new genes for resistance. Seventeen varieties and lines that contain resistance to Phytophthora were identified which can now be used in breeding programmes in Ontario. Groups of genes were identified to help explain the Phytophthora resistance in Conrad. Sclerotinia resistance will be screened, developed and verified in 2003. A survey has showed Rps 1c, 1k, 8 (new resistance gene, Ohio) and 939 (Harrow resistance gene) provided protection against Phytophthora races in eastern Ontario. The genes have potential to be used for breeding programmes in the future. This sort of project is will help Ontario producers over come disease issues which ultimately affect the bottom line. File:
