Project Deliverables

This project will expand on discovering novel vQTL not present in the germplasm already screened. While we can map large-effect, vQTL there is still a significant proportion of genes with small effects that will not be mapped due to the lack of power. Genomic selection is a method that is highly effective to enhance breeding for quantitative traits. Using genomic selection to help enhance germplasm for yield and seed composition stability has not been tested in soybean. This study will demonstrate its effectiveness for enhancing trait stability early in the breeding process. The findings from this work can be extended across the north central region of the U.S. to identify genes conferring yield stability across this larger region.

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.
