Sudden death syndrome (SDS) is caused by the pathogen Fusarium virguliforme and can cause severe yield losses in soybeans. The disease has been a serious problem in the southern states. In recent years it has spread to the northern states. The disease first appeared in Michigan in 2008 and was found in more locations in the following years. The disease was randomly scattered throughout most Michigan fields and caused small impact on overall yield. However, it has prompted concerns from growers about the disease and the need for varieties that have resistance to the pathogen. Using SDS resistant varieties has been recommended as the best strategy to control the disease. However, SDS resistance...
The evaluation will be based on the progress of the project according to the above plan of work.
Updated February 21, 2017:Greater than 20,000 plants with recombination break point near the resistance genes were evaluated for SDS resistance in the Decatur SDS nursery. Leaf tissue was collected from these plants and DNA was extracted.
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.
