Soybean varieties that are resistant to the soybean cyst nematode (SCN) allow farmers to produce the crop profitably in SCN-infested fields.
Roughly 95% of SCN-resistant soybean varieties have SCN resistance from the soybean breeding line PI 88788.
The continued use of soybean varieties with such a narrow genetic base of SCN resistance has resulted in selection of SCN populations with increased reproduction on resistant varieties in fields.
In the latest Focus on Soybean presentation, titled “Increased Reproduction of Soybean Cyst Nematode and Yield of SCN-Resistant Soybean Varieties” Dr. Gregory Tylka at Iowa State University discusses the role and nature of SCN-resistant soybean varieties and the effects of elevated SCN reproduction on the yield of SCN-resistant soybeans.
This 24-minute presentation is open access through November 30, 2012. Viewers can also opt to see a 5-minute executive summary version of this presentation.
