Brief Project Summary:

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

Information And Results
Final Project Results

Update:
SCN populations from Seneca (Hg-2.5.7), Crawford (1.3.5.6.7) and Putnam (1.2.3.5.6.7) counties that were originally maintained on SCN resistant soybean Peking and PI88788 have been isolated and split and planted onto Peking and PI 88788. Populations are being assessed for changes in Hg-type. - SCN females from Putnam and Williams county were found growing on PI 437654. The eggs from these collected cyst were placed onto Hutcheson and amplified. Collected cyst were placed back onto PI88788, Peking and PI 437654. Cyst were collected from all three and are being amplified for Hg typing.

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.
