Soybean cyst nematodes (SCN) are a major pathogen of soybean inflicting significant yield losses in the United States. Though Ohio extension regularly screens and finds SCN in Ohio counties, little information is available on the diversity of SCN populations. Overuse of SCN resistant soybean lines and our limited understanding of the genetic diversity in SCN populations in Ohio threaten the long-term survivability of SCN resistant soybean for nematode control.
