The objectives of this research are to survey the utilization types of radish and its adapted cultivars and to investigate the desirable traits in Japan. Many types of radish cultivars which hold diversified characteristics have been released according to the cropping type. Qualities and shape demanded in Japan was very different from Korean type radish cultivars. To meet the rapid require ment of our radish seed in Japan, we have to take the following measurements urgently: (1) to breed higher quality cultivars adapted for the utility of radish, (2) to secure various genetic resources of radish and (3) to develop cultivars resitant to specific pests and pathogens.
