Research Project: Development of Soybeans with High Yield and Higher Seed Protein with Improved Amino Acid Composition and Low Phytate

Location: Soybean and Nitrogen Fixation Research

2011 Annual Report


1a.Objectives (from AD-416)
To improve selection methods for high-yielding protein soybean varieties, populations for northern and southern varieties with higher protein and lower phytic acid, and improve the amino acid composition of seed proteins.


1b.Approach (from AD-416)
Continuation of breeding programs to combine or introduce genes that enable development of agronomic soybean germplasm with superior meal attributes that include increased total metabolizable energy, improved essential amino acid balance, and enhanced digestibility for feed applications. Research involving DNA marker methodology will be subcontracted through SCA to cooperators at UT, UGA, and NCSU.


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 Minnesota, South Dakota, Missouri, Arkansas, Tennessee, North Carolina, and Georgia. 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. Specific cooperative agreements have been activated, derivative to this project. Research is being initiated.
