Brief Project Summary:

SCN-resistant soybean varieties are critical for managing SCN. The scientific definition of an SCN-resistant soybean variety is one that allows 10 percent or less SCN reproduction relative to a standard susceptible variety in greenhouse testing. Not all soybean varieties described as resistant to SCN truly are. In fact, some "SCN-resistant" varieties are completely susceptible, allowing unchecked SCN reproduction. This project provides comprehensive information about how well "SCN-resistant" soybean varieties suppress nematode population densities and how well the varieties yield in SCN-infested fields in Iowa. The project also is revealing relationships between SCN population HG types and yield loss on SCN-resistant soybean varieties with the different sources of resistance.

Key Benefactors:
farmers, agronomists, Extension agents, seed companies, soybean breeders

Information And Results
Final Project Results

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.
