얼룩찰1호'는 자식계통 KBW23을 종자친으로 하고 KW33을 화분친으로 하여 교잡된 단교잡종이며 알맹이가 흰색과 검정색의 두 가지 색을 가진 얼룩찰 옥수수이다. '얼룩찰1호'는 2003년 생산력검정시험을 거쳐, 2005년부터 2007년까지 3년 동안 전국 5개 지역에서 지역적응시험을 실시한 결과 그 우수성이 인정되어 2007년 농작물 직무육성 신품종으로 결정되었다. 이 품종의 주요특성을 요약하면 다음과 같다. 1. '얼룩찰1호'의 출사일수는 76일로
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.
