Seeds of 'Sansai' variety, line No. 34-9-1 (white flower, as a female parent) were irradiated with gamma rays of a cesium137 source; 5 and 15 krad were used. After treatment, Sansai seeds were grown in alternate rows with S.J. 1 line No. 56-12 and S.J. 2 line No. 27-9 (both purple flowers, as male parents) . The experiments were carried out in replications on Kasetsart campus and at Suwan Farm, Pakchong.
