Soybean cyst nematode (SCN) has overcome the PI 88788 resistance, which farmers have relied on for over three decades. Although the Peking lines were previously associated with a reduction in yield within soybean lines, researchers from Iowa State University have demonstrated that you can now find commercially available varieties with Peking resistance that outperform PI 88788 in regions with high SCN pressure. Dr. Mandy Bish from the University of Missouri Extension discusses the limited availability of Peking options in preferred maturity groups for farmers but emphasizes the importance of a corn rotation and use of resistant varieties to help decrease SCN populations.
