큰섬'은 국립식량과학원 기능성작물부에서 재배안전성이 높은 초다수성 벼를 육성하고자 1996년 하계에 초형이 양호하고 흰잎마름병에 저항성이며 초다수성인 '다산벼'에 벼멸구와 바이러스에 저항성인 남영벼를 인공교배 하였다. 그 후에는 집단육종법과 계통육종법을 병행 실시하여 미질이 좋고 생육특성이 양호한 계통 YR18234-B-B-98 -3-5-1을 선발하였다. 생산력검정 시험과 2003년부터 2006년까지 4년간 지역적응시험을 실시한 결과 그 우수성이 인정되
Keunseom' a new second generation Tongil-type rice variety (Oryza sativa L.), is a mid-maturing ecotype developed by the rice breeding team of Department of Functional Crop, NICS, RDA in 2006.
