Project Number: 6645-21220-068-09-S
Project Type: Specific Cooperative Agreement
Start Date: Apr 1, 2011
End Date: Mar 31, 2014
1. Develop breeding populations integrating high protein, low phytate and/or improved amino acid profiles with high yielding and other desired traits in maturity groups 0-II; 2. Develop and release new germplasm lines with high protein (40% at 13% moisture) and/or low phytate; 3. Develop and release high yielding varieties with improved protein and low phytate; and 4. Identify and validate breeder-friendly molecular markers associated with high protein.
Conventional breeding procedures will be predominantly employed. New high-protein lines (e.g. SD00-1501, M02-375017, M03-184050, M03-184083, E07130-T, E07147-T, etc.) and low phytate lines (e.g. M03-917303, M03-809146, etc.) will be crossed to high-yielding lines. SSD will used to advance generations and individual selection will also be conducted in early generations for major agronomic characters or resistance in some cases. Protein analysis will be performed by NIR and NMR. SSR markers and RIL population will be used for QTL mapping.
