Project Summary

The overall goal of the project is to provide Iowa soybean growers with a regular source of unbiased and complete information about the agronomic performance and soybean cyst nematode (SCN) control provided by soybean varieties marketed to Iowa growers as resistant to SCN. The existing ISU SCN-resistant Soybean Variety Trial Program will be expanded into a more comprehensive program for evaluation of a greater number of SCN-resistant soybean varieties sold in Iowa.

Project Objectives

1. Compile information each year about soybean varieties marketed as resistant to SCN that are available to Iowa farmers.
2. Assess each year the amount of SCN reproduction on the roots of SCN-resistant soybean varieties using SCN populations from Iowa fields in short-term greenhouse experiments under controlled environmental conditions.
3. Assess the agronomic performance each year of SCN-resistant soybean varieties in experiments conducted in fields infested with different SCN HG types at various locations throughout Iowa.
4. Measure each year the control of SCN population densities provided by SCN-resistant soybean varieties in experiments conducted in fields infested with different SCN HG types at various locations throughout Iowa.
