Brief Project Summary:

This research project's main objective is to map genes that are responsible for increasing soybean
yield stability. Most research looking at yield has tended to focus on genes that contribute to high yield
while ignoring the effect of yield stability across a large region of different environments. This
project is the first project to our knowledge which will evaluate how genes in the soybean
genome reduce yield variance leading to more consistent yields across farmer’s fields and in
different years.

Information And Results
Project Deliverables

This project will take the first steps in finding markers associated with yield
stability across Nebraska soybean production areas and to understand the genetics of yield
stability. Important environmental factors may include water, temperature, light, soil type and
fertility, and production system. This research will consider stability for factors other than
disease and insect pests, so those biotic factors will be controlled in these experiments with
prophylactic treatments on seeds and plants during the growing season. Through a better
understanding of yield stability we will be able to incorporate this key trait with high yielding
traits earlier in soybean breeding programs at the University of Nebraska and elsewhere to ensure
more consistent yields for soybean producers.

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.
