Brief Project Summary:

As part of an ongoing project funded by the United Soybean Board, we have identified soybean genotypes that are delayed in wilting when compared with most other genotypes. To determine wilting, we rate plots on a visual scale from 0 (no wilting) to 100% (completely wilted with dying leaves). Ratings for wilting are reproducible from year to year, they are heritable, and the delayed wilting trait increases yield under drought conditions. We have also been able to tag some of the genes for delayed wilting, but our ability to use molecular markers efficiently is limited by the number of soybean lines that we can rate for wilting.

Information And Results
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.
