Wheat, maize, chickpea, and mung bean seeds were irradiated at 0.5, 1.0, 2.5, and 5.0 kGy in a cobalt-60 gamma cell. Nonirradiated seeds served as controls. Comparison of amino acid profiles showed that sulfur- containing amino acids were radiation labile, particularly in the legumes. Significant losses in all cultivars also were noted for lysine, tyrosine, and isoleucine. However, the percent available lysine was higher in the irradiated seeds.
