Brief Project Summary:

The purpose of this research project is to continue development of high-yielding soybean cultivars with adaptation to Tennessee and the Mid-South region that contain the indeterminate growth habit, using a molecular marker to aid efforts and following a molecular back-crossing introgression approach. Research suggests that indeterminate soybean varieties have a greater potential for high yield and resistance to drought. This project seeks to demonstrate the feasibility of converting a determinate variety to an indeterminate variety using molecular trait introgression.

Key Benefactors:
farmers, agronomists, extension agents, soybean breeders, seed companies

Information And Results
Project Deliverables

The long term goal of this project would be to continue back crossing using the methods described above until BC3 (94% recurrent parent) or BC4 (97% recurrent parent) generation, and identify indeterminate breeding lines with excellent agronomic characteristics for yield testing and eventual cultivar release. This would provide Tennessee soybean producers with highly productive indeterminate cultivars with elite agronomic characteristics and ability to withstand drought. Simultaneous with this approach new forward and back crosses will continue in order to provide adapted indeterminate soybean varieties for Tennessee and Mid-South region.

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.
