Research Project: Development of Soybean Varieties with Higher Yield Potential and Higher Protein Concentration Using Molecular Marker Technology

Location: Soybean and Nitrogen Fixation Research

2011 Annual Report

1a. Objectives (from AD-416)
To develop productive group III, IV and V disease resistant, soybean varieties with improved protein, quantity, quality and stability.

1b. Approach (from AD-416)
Utilize classical and marker assisted breeding approaches to discover and introduce novel genes from adapted lines and plant introductions to develop high yielding group III, IV and V varieties with: a) 37% or greater protein and acceptable oil with resistance to nematodes and diseases, b) Improved lysine, methionine, cysteine, and other potentially limiting amino acids, c) Improve protein stability across environments, and c) Develop low phytate soybeans without seed germination issues.

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.
