This research is focused on identification and characterization of germplasm sources that have improved grain quality and nutritional value characteristics. Breeding projects to assemble these genes into improved cultivars should proceed rapidly with the aid of marker-assisted selection and with performance tests made in multiple environments. The results from these studies will contribute to the development of value-enhanced sorghum and millet grains and the transfer of animal feeding technologies will promote the development of new entrepreneurial opportunities for production of meat and other animal products in Africa and Central America.
Research: 1. Study the inheritance of seed size and feed quality components in sorghum; 2. Determine the metabolizable energy content of sorghum hybrids differing in seed size versus corn in poultry rations; 3. Identify, clone, and map genes for grain mold resistance, anthracnose resistance, and improved nutritional characteristics. Germplasm Development: 1. Develop sorghum varieties and hybrids with improved yield potential and food quality characteristics. 2.Develop recombinant inbred (RI) sorghum mapping populations to identify markers for grain mold resistance, anthracnose resistance, and improved nutritional characteristics. 3. Evaluate tan-plant food sorghum hybrids for differences in grain quality and food processing characteristics.Evaluate the feasibility of marker-assisted selection for grain mold resistance. Training, Networking, and Institutional Development 4. Identify graduate students from Central America and Africa through the aid of collaborators. 5. Establish formal and working collaborations and plans for work in Central America and Africa.
