Soybean cyst nematode is overcoming the main source of genetic resistance, PI 88788, used in 95% of commercially-available SCN-resistant soybean varieties, and negatively impacting yields. Farmers need new SCN resistant management strategies, such as expanding the use of Peking source of resistance, used in only 5% of commercial soybean varieties, new sources of SCN resistance, and stacking multiple sources of resistance in the same variety. The ultimate goal is to identify alternative resistance genes and gene combinations that, when used in rotation, will reduce SCN population densities and slow selection pressure on SCN to adapt.
