Technical Abstract: Peanuts from the Core Collection designated as the Core of the Core Collection were grown in Tifton, GA in 2005. Amino acids, folic acid and total oil content were determined on the whole seed. Amino acid concentrations were generally close to commonly reported values. Folic acid concentration varied from 100 to 240 micrograms per 100 grams and the higher concentrations exceeded normally reported values. Oil was mechanically expressed from the seed and analyzed for fatty acids and individual tocopherols. Common fatty acid profiles were observed and the highest O/L ratio was 3.5. Some samples had alpha tocopherol contents much higher than commonly reported. The higher concentrations of some nutrients indicated that the core of the core samples may have potential for improvements in nutrient profiles of peanuts when used in conventional breeding programs.
