The ninhydrin method was used to determine the free amino acid content of 14 maize endosperm mutants and their double-mutant combinations with opaque-2 in the Oh43, W64A, C103, and B37 inbred lines, and hybrid combinations of these lines. In all combinations studied, the introduction of the opaque-2 gene invariably raised the free amino acid content of the kernel above that found in the single mutant, inbred, or hybrid line.
