Soybean cyst nematode (SCN) continues to be a major threat to grower profitability. In recent years, SCN has spread all the way to the Red River Valley and more and more frequently, nematode isolates can overcome resistant varieties. Clearly, better resistant cultivars are needed to control a broader range of SCN races while also providing yield stability.

A primary objective of the University of Minnesota breeding program is developing Minnesota-adapted soybeans with robust SCN resistance in order to expand the options available for Minnesota growers. Here we propose continuing research to enhance SCN disease marker-based selection. Our project expands the use of novel resistance...
