To breed new highly antioxidative common buckwheat cultivars, we selected individual plants from gamma ray-irradiated populations. Selection and propagation were repeated 4 or 5 times. This recurrent selection process resulted in many individuals with enhanced antioxidative activity. Among them, 2 individuals from the forth selection and 9 individuals from the fifth selection were developed into lines with increased antioxidative activities and diverse polyphenolic composition. From these lines, 2 new cultivars ‘Gamma no irodori’ and ‘Cobalt no chikara’ were developed. Furthermore, following the selection of individuals with high rutin contents, ‘Ruchiking’ was developed.
