Abstract

'Mogwoo', a new high yield and whole crop silage rice (Oryza sativa L.) cultivar, was developed by the rice breeding team of the National Institute of Crop Science, RDA, Suwon, Korea, from 1999 to 2009, and was released in 2010. It was derived in 1999 from a cross between Dasanbyeo, having a high yield, and Suweon431/IR71190-45-2-1. A promising line, SR25848-C99-1-2-1, selected by the pedigree breeding method, was designated the name of 'Suweon 519' in 2007. This cultivar has about 155 days of growth period from seeding to heading, and is tolerance to lodging, with erect pubescent leaves as well as a long and thick culm. This cultivar has the same number of tillers per hill and higher spikelet numbers per panicle compared to Nokyang. 'Mogwoo' has longer leaves compared with other Tongil-type varieties. This new variety is resistant to grain shattering, leaf blast, bacterial leaf blight, and small brown planthopper. The biomass yield of 'Mogwoo' was 1,956 kg/10a in a regional test over three years. The result shows that 'Mogwoo' is adaptable to central and south-east plain areas of Korea.

'목우'는 총체사료용 벼 품종을 육성할 목적으로 1999년 하계에 다산벼를 모본으로 하고 수원 431호와 IR71190-45-2-1을 교배한 $F_1$을 부본으로 삼원교배하여 계통육종법으로 전개 후 2009년 총체사료용 벼로 육성하였다. 주요 농업적 특성은 중부와 영남평야지 보통기 재배에서 출수기가 평균 9월 2일로 녹양보다 17일 늦은 만생종이고 벼 키 (간장)는 92 cm로 장간이며, 주당수수는 11개, 천립중은 21.7 g으로 녹양보다 가볍다. 만생종 품종으로 숙기가 늦기 때문에 생육후기 기상이 불량할 경우 출수가 지연될 수 있는 산간지, 냉수용출답 및 만식재배는 피하는 것이 좋으며 충분한 생육일수를 확보하는 것이 총체수량성을 높이고 충실한 종자를 생산하는데 유리하다. 또한 주당수수가 적기 때문에 $m^2$당 27주 이상 밀식재배가 필요하며 내비성이 있으므로 질소 시비량을 180 kg/ha 수준으로 유지하는 것이 유리하다. 재해저항성은 잎도열병, 흰잎마름병, 바이러스병에 복합저항성이나 목도열병과 벼멸구에는 약하다. 총체벼 품종으로서 사료가치는 조단백질 5.4%, 가소화양분총량 61.6%으로 양호한 편이나 녹양보다 낮은 경향이며 총체수량성은 건물기준으로 10 a당 평균 1,956 kg으로 녹양보다 38% 증수되는 경향을 보였다. 이 품종의 재배에 알맞은 지역은 중부평야, 영남평야지가 적합하며 후기 기상이 좋은 지역이 안전하다.
