영문 초록

A new single cross hybrid, ‘Guseulok’, is a bicolor sweet corn (Zea mays L.) developed by the maize breeding team at the National Institute of Crop Science (NICS), RDA in 2009. This hybrid, which has a good eating quality and high sugar content, was produced by crossing two inbred lines, KSE19 and KSE7. KSE19 was the seed parent and KSE7 was the pollen parent of ‘Guseulok’. Ear length and diameter of ‘Guseulok’ were 18.0 cm and 4.6 cm, respectively. The ratio of kernel set length/ear length was 90%, similar with that of a check hybrid, ‘Golden Cross Bantam70’ (GCB70). However, the free sugar content was 20.5%, higher than ‘GCB70’, 14.0%. It is resistant to Bipolaris maydis (Southern corn leaf blight) and its lodging resistance is excellent. The yields of ‘Guseulok’ in fresh ear weight were similar with those of GCB70 in regional yield trials (RYT) from 2007 to 2009. Seed production of this hybrid has gone well due to good match during crossing between the seed and pollen parents. It is adaptable to the whole country. Plant variety protection right of ‘Guseulok’ was registered in January 2013, and its grant number is 4322.
