A new waxy corn hybrid ‘Daedukchal 1’ was developed from single cross between CNU 504 and CNU 2396 at Chungnam National University in 2007. Inbred CNU 504 used as a seed parent and inbred CNU 2396 as a pollen parent were collected throughout domestic regions. Tasseling date of this hybrid was seven days later than that of check hybrid, ‘Chalok 1’. ‘Daedukchal 1’ was 19.7 cm in ear length and 4.5 cm in ear diameter. On yield trial, ear length of this hybrid was increased 29.7% compared with a check hybrid, ‘Chalok 1’. ‘Daedukchal 1’ had white kernels and good eating quality due to high sugar content and thinner pericarp. The ratio of kernel set length/ear length was similar to ‘Chalok 1’. It is moderately resistant to southern leaf blight and northern leaf blight but susceptible to corn borer. The yields of ‘Daedukchal 1’ in fresh ear weight and in number of fresh ear were 16% and 8%, respectively, higher than those of a check hybrid in regional yield trials for two years. Seed production for this hybrid was better because of the consistency of tasseling dates.
