Information And Results
Project Deliverables

• Preliminary report on yield performance of commercial cultivars by the end of year 2 and an expanded report at the end of year 3.
• Release of at least one new germplasm by the end of year 3.
• Quantification of the impact of the slow-wilting trait on seed yield under stress in year 3.
• Quantification of the impact of drought and the slow-wilting trait on seed protein content under stress by the end of year 3.
• Completion of a GWAS study on slow wilting by year 3.
• Backcrossing at least one generation of QTLs into elite varieties using MAS in year 3.
• Quantification of phenotypic data for QTL mapping for slow-wilting by the end of year 3.
• Complete the survey of drought tolerant breeding stock for intrinsic water-use efficiency and report results by the end of year 3. Identify high- and low- intrinsic water-use efficiency progeny from Fiskeby III by the end of year 3.
• Report on the drought threshold for slow-wilting trait advantage by the end of year 3.
• Report on the relations between photosynthesis, leaf water potential, and slow wilting by the end of year 3.

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.
