Brief Project Summary:

The goal for this research is to provide producers with technologies to minimize soybean yield loss to the top three Soybean Diseases causing economic damage to the Midsouth including Tennessee. Screening for charcoal rot resistance has shown that of all the lines evaluated only nine exhibited 100 % resistance across three replications. Three of these lines are in MG II, 2 in MG IV and 3 in MG V and 1 in MG VI. Six of these lines also have SCN resistance. Additional 51 lines were shown 91-99 % to have some resistance. These lines will continue to be evaluated and validated for true and high level of resistance over the next two to three years. Most current soybean cultivars in the United...

Final Project Results

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.
