Brief Project Summary:

There are several possible targets for improving soybean yield if the genetic gain equation is considered. These targets include increasing the selection intensity, increasing measurement accuracy, increasing genetic diversity and additive genetic variance, and decreasing the amount of time required for each breeding cycle. Through coordinated activities across 12 breeding programs in the North Central region, the project objectives address one or more of the target areas. The final objective is aimed at developing a metric to accurately assess realized genetic gain for yield on an annual basis.

Key Benefactors:
farmers, geneticists, breeders

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.
