Research Project: Develop High-Yielding Mg4-6 Soybean Cultivars/ Germplasm with High Protein, Low Phytate, and Desirable Sugars for the Meal Market

Location: Soybean and Nitrogen Fixation Research

2011 Annual Report


1a.Objectives (from AD-416)
Develop and release new MG4-6 conventional and RR breeding lines with high protein, high sucrose, low stachyose, low phytate, and high yield potential as variety or germplasm.


1b.Approach (from AD-416)
Develop and test, using conventional breeding methodology, a large number of lines and breeding populations for combining high protein, high digestible sugars, low oligosaccharides, and low phytate in the elite background. Our goal is for the yield level of the best high protein and low phytate lines to be comparable to popular commercial varieties. We will also develop a number of lines with low phytate and/or low stachyose without seed germination problems.


3.Progress Report

This project is related to Objective 2 of the in-house project: To discover novel genes/alleles in soybean for seed composition, determine their inheritance, determine genomic location, transfer to adapted germplasm, and release.

This is a new on-going research project that implements long and short-term goals to improve intrinsic quality of soybeans. The strategies are addressed by 14 subprojects conducted by 13 outstanding scientists from MN, SD, MO, AR, TN, NC, and GA. The combined expertise of this team in plant breeding, biology, genetics, pathology, and physiology will provide genetic resources, genomic tools, and fundamental information needed to expedite development, evaluation, and commercial production of agronomic soybean varieties exhibiting superior meal attributes that include increased total metabolizable energy, improved essential amino acid balance, and enhanced digestibility for feed applications.

This project has been active only since April 2011. Research is being initiated.

The Authorized Departmental Officer's Designated Representative monitored activities of project through frequent phone calls and emails.
