Heterodera glycines, commonly called the soybean cyst nematode (SCN), is a chronic disease of soybean that lowers yields throughout the North Central United States. There is a critical need for effective management approaches to lower SCN populations. SCN is currently managed with rotations of non-host crops and the use of SCN resistant soybean cultivars. SCN resistant soybean can be effective, but since SCN is genetically diverse and adaptable, virulent nematodes (SCN that grow and reproduce on a resistant plant) are a growing problem. This is also due to the over reliance upon one source of SCN resistance from soybean PI88788. However, if virulent SCN accumulation could be monitored in...
