Abstract
'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's 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.
