Abstract

Soybean cyst nematode (SCN) was identified in Iowa less than 30 years ago and is now recognized as a major pest of soybeans, particularly in sandy soil regions such as the Muscatine Island. Effective management has relied on crop rotation and the use of resistant varieties. Recently, some SCN resistant varieties have not been performing to expectations in certain fields. The reason for this is thought to be the repeated use of varieties obtaining their resistance from a single source, PI 88788, which has led to the development of SCN populations resistant to PI 88788. This project was initiated to help identify soybean varieties with different and effective sources of SCN resistance to provide management choices that will maintain soybean profitability.
