조생 단간 내도열병 반투명 중간찰 벼 ‘월백’

국문 초록 (Abstract)

‘월백’은 조숙 내병 고품질 중간찰 계통을 육성할 목적으로 2000년 하계에 중간찰 품종인 ‘Milkyqueen’에 조숙 내병 고품질 품종인 ‘그루벼’를 인공교배하여 2010년 육성된 조생 내도복 반투명 중간찰 품종으로 주요 특성을 요약하면 다음과 같다. ‘월백’의 보통기 보비재배에서 출수기는 평균 7월 31일로 ‘오대벼’보다 1일 늦은 조생종이다. ‘월백’의 간장은 67 cm이며, 주당수수는 16개, 수당립수는 59개이고, 현미천립중은 21.4 g 으로 ‘오대벼’보다 가볍다. ‘월백’의 아밀로스함량은 11.6%로 중간찰이고 쌀 외관은 투명도가 4로 반투명해 보인다. ‘월백’은 위조에 강하고 불시출수가 잘 되지 않으며 성숙기에 하엽 노화가 느린 편이다. ‘월백’은 수발아에 강한 편이고, 내랭성은 ‘오대벼’와 비슷한 수준이다. ‘월백’은 잎도열병에는 강한 저항성이고 흰잎마름병, 바이러스병 및 해충에는 약하다. 지역적응시험 보통기 보비재배에서 평균 쌀 수량이 5.13 MT/ha로 ‘오대벼’ 대비 95%의 수량성을 보였다. ‘월백’의 재배적지는 북부평야지, 중산간지, 남부고랭지 및 동북부해안지이다.

다국어 초록 (Multilingual Abstract)

‘Wolbaek’ is an early-maturing, semi-transparent low amylose content variety developed from a cross between ‘Milkyqueen’ and ‘Geuroobyeo’ by the rice breeding team of National Institute of Crop Science, Rural Development Administration (RDA) in 2000. ‘Wolbaek’ has about 102 days duration from seeding to heading in middle plain, mid-northern inland plain, southern alpine and north-eastern coastal areas. It is about 67 cm in culm length with semi-erect plant type and good canopy architecture. ‘Wolbaek’ has 16 tillers per hill and 59 spikelets per panicle. Its 1,000 grain-weight of brown rice is 21.4 g which is less than that of ‘Odaebyeo’ (26.4 g). The milled kernels look like semi-transparent dull because amylose content of this variety is about 11.6%. This variety shows strong resistance to cold treatment, lodging and wilting. ‘Wolbaek’ shows resistant to blast disease but susceptible to bacterial blight, stripe virus and insect pests. The milled rice yield performance of this variety is about 5.13 MT/ha by ordinary culture in local adaptability test for three years. ‘Wolbaek’ may be highly adaptable to the middle plain area, mid-northern inland plain area, southern alpine area and north-eastern coastal areas of Korea.
