Ohio Extension and the Ohio Plant Diagnostic Network regularly screens and finds soybean cyst nemaotde in Ohio counties. Work in this laboratory has focused on screening SCN populations from Ohio for their ability to grow on SCN resistant soybean germplasm. Recent findings have shown that most SCN population collected from Ohio are now virulent on some of the most widely used SCN-resistant soybean varieties. The goals of this project are to continue to evaluate the levels and genotypes of SCN populations in Ohio, gather evidence for shifts in SCN genotypes in virulent strains of SCN when alternative SCN resistant germplasm is used, and examine Ohio State's breeding germplasm for new SCN resistance genes. Key Benefactors: farmers, agronomists, extension agents
1. Knowledge of SCN populations and virulence in Ohio. 2. Knowledge of how SCN populations shift when alternative SCN resistant germplasm is used. 3. Identification of new SCN-resistant genes.
The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
