Soybean cyst nematode (SCN) is the most yield-reducing pathogen in the U.S. soybean production. Over 95% of the SCN-resistant commercial varieties utilize the Rhg1 locus derived from PI 88788, but there is extensive variation in the performance of these varieties under SCN pressure. In addition, Rhg1 is not effective against all SCN field populations and it is dangerous to rely solely on one resistance locus for SCN control.
The ultimate goal of the project is to identify genetic markers for SCN resistance and soybean genes that can be altered in infected soybean tissue to disrupt SCN development.
