A new single cross waxy corn (Zea mays L.) hybrid, “Miheugchal” with black kernel was developed by the Maize Experiment Station (MES), Gangwon-do Agricultural Research and Extension Services (GARES) in 2004. This hybrid, which has good eating quality and high yield of fresh ear weight, was produced by the cross between two inbred lines, HW7 and HW8. Inbred HW7 was derived from Yanggu Bangsan local variety and inbred HW8 was derived from Hwacheon local variety, were collected by MES in 1996. Two inbred lines were advanced to seven generations by ear-to-row method. The silking date of this hybrid is about thirteen days later than that of check hybrid “Chalok 1”. Ear length (17.7 cm) is longer than that (16.0 cm) of check hybrid. It is moderately resistance to lodging and highly resistance to E. turcicum, but moderately resistance to B. maydis. This hybrid has better eating quality check hybrid “Chalok 1”. The yield of “Miheugchal” in fresh ear number and fresh ear weight were 2% and 34% higher than those of a check hybrid “Chalok 1” during three years of regional yield trials.
