The main focus of the study was to investigate the changes in protein content due to radiation mutagenesis by comparing the protein profile of amaranth mutant lines with that of untreated controls. We have found several promising lines with high coefficients of nutrition quality. Considering overall nutrition values, the line C82/1 is the most promising genotype, which could be possibly used in a future breeding programme. The protein composition of amaranth seeds can be changed and their nutrition values significantly influenced through radiation mutagenesis.
