영문 초록

A new single cross waxy corn (Zea mays L.) hybrid, “Mibaek 2” with white kernel was developed by the Maize Experiment Station (MES), Gangwon-do Agricultural Research and Extension Services (GARES) in 2005. This hybrid, which has good eating quality, high yield of fresh ear weight and lodging resistance, was produced by the cross between two inbred lines, HW9 and HW3. Inbred HW9 was derived from Jewon/Bosung//KW7 and inbred HW3 was derived from W9060/A632wx. Two inbred lines were advanced to eight generations by ear-to-row method. The silking date of this hybrid is about six days later than that of check hybrid “Chalok 1”. Ear length (18.8 cm) is longer than that (15.8 cm) of check hybrid. It is highly resistance to B. maydis (southern leaf blight) and E. turcicum (northern leaf blight), and has high lodging tolerance. This hybrid has better eating quality than “Chalok 1”. The yields of “Mibaek 2” in fresh ear number and fresh ear weight were 1% and 26% higher than those of a check hybrid “Chalok 1” during three years of regional yield trials, respectively.
