Research Project: SOYBEAN PROTEIN IMPROVEMENT ACCELERATED BY PERFECT MOLECULAR MARKERS

Location: Plant Genetics Research

2010 Annual Report


1a.Objectives (from AD-416)
Evaluate the progress that can be achieved in developing soybean germplasm with improved meal value utilizing perfect molecular markers.


1b.Approach (from AD-416)
1. Make crosses and develop initial populations segregating for tractable meal traits. 2. Use molecular markers to select desired genotypes. 3. Backcross selected genotypes and develop segregating populations. 4. Advance material identified with desired genotypes. 5. Evaluate meal trait phenotypes and agronimic characteristics of lines.


3.Progress Report

Research continued to investigate the ability to combine multiple genes important for soybean seed meal quality into a single soybean line. The project progressed by incorporating the missing gene conferring the low phytate trait into the germplasm. Efforts are currently focused on characterizing the phenotypes of all developed lines and identifying lines that may be suitable for germplasm release.

Monitoring activities included email exchange of information and results in quarterly reports, and participation in the United Soybean Board Soybean Seed Composition Workshop in February in St. Louis, Missouri.
