초록
‘Dasan 1’, a new Tongil-type rice (Oriza sativa L.) cultivar, was developed by the rice breeding team of National Crop Experiment Station, R.D.A., Suwon, Korea during the period from 1997 to 2006 and released in 2007. It was derived from a cross between Bengal/Youngmoonbyeo and Dasanbyeo. This cultivar has about 130 days of growth duration from seeding to heading and is semidwarf(culm length 81 cm). It has erect pubescent leaves and tough thick culm with strong lodging tolerance. This cultivar has a few less tillers per hill and markedly more spikelet numbers per panicle. ‘Dasan 1’ is strong to cold tolerance under the low temperature condition. This new variety reveals relatively rapid leaf senescence and strong tolerance to viviparity during the ripening stage. This cultivar is considerably multi-resistant to blast, bacterial leaf blight, and virus disease. Milled rice of this variety is non-glutinous endosperm with slightly less translucency and more chalkiness compared with japonica high-quality rice. Its rice kernel is medium size, slightly longer and larger than those of Dasanbyeo. It has 18.6 % amylose content and low gelatinization temperature. The yield performance of ‘Dasan 1’ is 7.18 MT/ha in polished rice in local adaptability test for three years. ‘Dasan 1’ is adaptable to central plain area, mid-western coastal area of Korea.
