2011 Annual Report
For Objective 2: We have developed a breeding line, G03-3666, with 32 g/kg of cysteine + methionine. Year 1: We will select lines with G03-3666 alleles at the four sulfur-containing amino acids QTLs. In addition we have crossed G00-3213 with the BC5 line Haskell containing the Lg-I high protein allele from Danbaekkong and the Lg-N and Lg-L low phyate alleles from CX1834-1-2. We will pyramid the high protein allele from Danbaekkong, the low phytate QTL alleles from CX1834-1-2, and the high sulfur-containing alleles from G03-3666 into G00-3213. This will be achieved by the development of two parallel backcross populations, one backcross population to incorporate the Lg-I high protein allele from Danbaekkong and Lg-N and Lg-L low phytate alleles from CX1834-1-2 into G00-3213 and the other backcross population to incorporate the elevated sulfur-containing amino acid alleles from G03-3666 at the Lg-C2, Lg-O, and Lg-L QTLs into G00-3213. We will make the 1st and 2nd backcrosses. Year 2: Make the 3rd and 4th backcrosses. Year 3: Make the 5th backcrosses. Once the backcross 5 has been achieved for these two populations, we will cross the two backcross 5 populations to pyramid high protein, low phytate, and elevated sulfur-containing amino acids into the conventional G00-3213.
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. Research is being initiated.
The Authorized Departmental Officer's Designated Representative monitored activities of project through frequent phone calls and emails.
