Trial Results Show Dual Benefits of SCN Resistance - 1/17/2014

Resource
The soybean cyst nematode (SCN) continues to be a major yield-reducing pathogen of soybeans in Iowa, and it occurs in up to 75 percent of fields in the state. Growing SCN-resistant soybeans is an important part of managing SCN. Results from Iowa State University’s nine SCN-resistant variety trial experiments in 2013 illustrate how resistant varieties can produce high yields and suppress the buildup of the nematode in infested fields. The ISU SCN-resistant Soybean Variety Trial Program, in its 23rd year of operation, is funded by the soybean checkoff through a grant from the Iowa Soybean Association. The program is the largest and most thorough at evaluating SCN-resistant varieties for agronomic performance and nematode control in the United States.
