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.
