초록
A single cross hybrid, ‘Eolrukchal 1’, is a bicolor waxy corn (Zea mays L.) developed by the maize breeding team at the National Institute of Crop Science (NICS), RDA in 2007. This hybrid, which has a high eating quality, was produced by crossing two inbred lines, KBW23 and KW33. KBW23 was a seed parent and KW33 was a the pollen parent of ‘Eolrukchal 1’. Ear length and diameter of ‘Eolrukchal 1’ is 18.4 cm and 4.5 cm, respectively. The ratio of kernel set length/ear length is 89%, similar with that of a check hybrid, ‘Chalok 1’. It is resistant to Exserohilum turcicum (Northern corn leaf blight) and its lodging resistance is higher than that of ‘Chalok 1’. The yield of ‘Eolrukchal 1’ in fresh ear weight was 9.80 ton/ha and 14%higher than that of ‘Chalok 1’ in regional yield trials (RYT) from 2005 to 2007. A seed production of this hybrid has been well due to good match during crossing between the seed and the pollen parents. It is adaptable to the whole country except Jeju-do.
