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. This variety was originated from a cross between 'Dasanbyeo'and 'Namyeongbyeo'in 1996' summer season, which developed by pedigree breeding method. The pedigree of 'Keunseom'was YR18234-B-B-98-3-5-1, and it was designated 'Milyang202'in 2002. 'Keunseom'has tolerance to lodging, because it has short culm length as 77 cm. This variety is resistance to bacterial blight K1 race, rice stripe virus, rice dwarf virus, and leaf blast disease. Milled rice kernel of 'Keunseom'is a clean translucent with non-glutinous endosperm, and has good quality as it was clear in chalkness. The milled rice yield potential of 'Keunseom'was about 719 kg/10a at ordinary fertilizer level of local adaptability test. This cultivar would be adaptable to the mid and southern plain of Republic of Korea.
