Brief Project Summary:

Soybean cyst nematode (SCN) is one of the most damaging soybean pests in Michigan and the incidence and severity of sudden death syndrome (SDS) has increased dramatically in Michigan since its first identification in the state in 2008. Past research has shown that yield reductions from SCN and SDS can be significantly reduced through the use of resistant or tolerant varieties. However, research is needed to identify and isolate new genetic sources of SDS resistance to improve the performance and availability of SDS and SCN tolerant varieties adapted to Michigan. The objectives of this project are to evaluate advanced breeding lines for SDS tolerance and SCN resistance and to integrate these...

Information And Results
Project Deliverables

Over 100 entries from the Advanced Yield Trials (AYT) will be planted at the Decatur site as they will be planted at other AYT sites. The soybean entries will be rated for SDS resistance at the R5 to R6 growth stages using the SDS disease severity rating scale developed at Southern Illinois University. The plots will be harvested for yield data.

Final Project Results

Updated February 17, 2020:
Progress made in 2019:
Over 200 advanced breeding lines were evaluated in the Decatur disease nursery. The nursery showed high SDS disease pressure and helped us determine the resistance levels of the breeding lines. It proved again the nursery was the best naturally infected SDS nursery in the US.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
