Database Research Summaries2018 Continuation of sudden death syndrome and soybean cyst nematode research at the soybean disease research center in Decatur
Research Focus
The focus of this project is to evaluate new soybean varieties for resistance to soybean sudden death syndrome (SDS), determine the effects of seed treatment on SDS and soybean cyst nematode (SCN), and examine the interaction between SDS and SCN.
Objectives
- Evaluate advanced breeding lines for SDS tolerance.
- Examine the SCN/SDS interaction.
Results
- Over 300 new varieties were evaluated for SDS resistance in 2018. The effects of various seed treatments on SDS and SCN were determined, and the SDS/SCN interaction was examined.
- The advanced breeding lines and commercial soybean varieties were planted in early May 2019 at the Soybean Disease Research Center in Decatur. Heavy and relatively uniform SDS symptoms were observed on susceptible varieties.
Importance
Soybean Cyst Nematode is the most damaging soybean pest in Michigan. The results from these projects will be published and distributed to Michigan soybean producers providing them with new and effective information for reducing yield losses from SCN and SDS in Michigan.
