Dry dormant seeds of sunflower cultivar VNIIMK - 8931 were irradiated with 15O Gy gamma rays (Co60). The influence of the mutagen was determined in the M1 generation. In the M2, Ma, and M5 generations, there were plants with lightly yellow cotyledons that died. Some mutated plants were isolated and self-pollinated for several generations. New sunflower forms with inherited changes were obtained through selection and self-pollination. One of the new forms was characterized by modified leaf and leaf petiole characters. The leaves were light green, lustrous, with a well-expressed vein. The leaf edges were serrated and runcinated with sharp points. The petioles had a joint near the leaf blade. The plant form was similar to an ornamental cabbage type. These plants had other important characteristics that were of interest for selection. This mutant has been noted as M 95-674. It can be used as an ornamental form as well as for heterosis breeding.
