다산1호'는 내랭성이 강한 통일형 초다수 벼 품종을 육성하기 위하여 1997년 하계에 Bengal/Yongmoonbyeo F1에 Dasanbyeo를 삼원교잡시켜 계통육종법에 의하여 육성한 품종으로, 2006년 12월에 직무육성신품종선정위원회에서 신품종으로 결정되었는데 그 주요특성을 요약하면 다음과 같다. '다산 1호'의 출수기는 보통기 재배에서 8월12일로 다산벼보다 2일 정도 늦은 중생종이며, '다산 1호'의 도열병, 흰잎마름병, 호엽고병 및 오갈병에
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.
