  A new single cross waxy corn hybrid, "Mibaekchal" with white kernel was developed by the Maize Experiment Station(MES) of Gangwondo Agricultural Research and Extension Services(GARES) in Hongcheon in 2001.  "Mibaekchal", which has high yield and good grain quality traits, was made by cross between two inbred lines, the seed parent, HW3, and the pollen parent, HW4.  Inbred HW3 derived from a single cross hybrid, W9060/A632wx, was used as the seed parent of "Mibaekchal", and inbred HW4 segregated from Anseong local variety as the pollen parent.  Two inbred lines advanced to eight and seven generations by ear-to-row method respectively.  The silking date of this hybrid is about six days later than that of check hybrid, Chalok 1.  Ear length(20.0㎝) was longer than that(16.2㎝) of check hybrid.  Plant and ear height were higher than that of Chalok 1.  It is moderately resistance to lodging and highly resistance to E. turcicum and B. maydis.  "Mibaekchal" had grain qualities and its panel test showed better than those of Chalok 1.  The appearance and sweetness of "Mibaekchal" were greater traits.  Number of the fresh ears and ear weight were 60,44 ears per ha and 9.3MT per ha, respectively, in Gangwon regional yield trial.  The yield of "Mibaekchal" in ear number and weight were increased 2% and 29%, respectively, compare with a check variety, Chalok 1, in regional yield trials for 3 years.
