Abstract

"Deuraechan" is a new japonica rice variety developed and registered by the rice breeding team of Department of Rice and Winter Cereal Crop, NICS, RDA in 2008. This variety was derived from a three way cross Iksan438, YR19105Acp222 and Milyang165. This variety has about 122 days of growth duration from transplanting to harvesting in Honam and Youngnam plain of Korea. It is about 76 cm in culm length and tolerance to lodging. In reaction to biotic stresses, it shows moderately resistance to blast, resistance to bacterial blight pathogen races from $K_1$ to $K_3$, and Rice stripe virus, but susceptible to other major diseases and insect pests. The milled rice of "Deuraechan" has high Quality, midium short grain. The milled rice yield of this variety is about 6.52 MT/ha in local adaptability test for three years. "Deuraechan" would be adaptable to Middle plain, Honam plain and Youngnam plain area of Korea.

"드래찬" 품종은 국립식량과학원 벼맥류부에서 2008년도에 육성한 중만생 양질 내병성 품종으로 주요특성과 수량성을 요약하면 다음과 같다. 1. 출수기는 보통기 보비재배에서 8월 17일로 한마음보다 2일 늦은 중만생종이다. 2. 쌀은 복백이 약간 있으나 아밀로스 함량이 낮고 밥맛이 좋은 편이다. 3. 도열병, 흰잎마름병 레이스K1-3 및 줄무늬잎마름병에는 저항성 반응을 보였으나 멸구 및 매미충류에는 약한 반응을 보였다. 4. 유묘 내냉성은 한마음과 비슷하나 임실율은 약간 낮다. 5. 쌀수량은 보통기 다비재배에서 6.52 MT/ha로 한마음보다 2% 증수되었다. 6. "드래찬"은 중부이남 평야지 1모작지에 알맞은 품종이다.
