Soybean cyst nematode (SCN, Heterodera glycines) is considered to be the most economically damaging disease of soybeans in Wisconsin, causing significant financial losses to growers every year. Rhg1 is the soybean genetic locus with by far the largest impact on SCN resistance, and is a key feature of current soybean varieties. However, a significant percentage of Wisconsin SCN populations are less well controlled by the Rhg1 alleles that are deployed in most commercially available soybean varieties. They recently identified the genes and genetic structure at the Rhg1 locus that are responsible for SCN resistance. They discovered that SCN resistance is controlled by three distinct genes at...
