초록
‘진수미’는 국립식량과학원에서 2008년도에 육성한 품종으로, 도정특성이 우수하며 쌀의 외관과 밥맛이 양호한 고품질 품종이다. 남서부 해안지 및 영호남 평야지 보통기 보비재배에서 평균 출수기는 8월 15일로 ‘남평벼’보다 2일 빠른 중만생종 품종이다. 간장은 85 cm로 ‘남평벼’보다 7 cm 정도큰 편이며, 완전미 도정수율은 96.6%로 ‘남평벼’와 같았다. 내냉성 검정결과 ‘남평벼’의 58%에 비해 상대적으로 높은 71%의 높은 임실율은 보였다. 수발아는 발생하지 않았으나, 담수직파 포장검정에서 약간 도복 되었다. 잎도열병은 중도저항성을 보였으며, 흰잎마름병 레이스 K1, K2, K3에는 저항성이었으나 K3a에는 이병성이며, 줄무늬잎마름병에는 강하였으나 기타 바이러스병에는 약하고 주요 해충인 벼멸구와 애멸구에는 저항성이 없다. 쌀 수량성은 5.55 MT/ha로 ‘남평벼’ 와 같았으며, 영남평야 1모작지가 적응지역이다.
Abstract
Recently, concerns have been voiced about the high eating quality rice in the market. To cope the high quality demands in rice market, a rice cultivar ‘Jinsumi’ which is showing high grain quality and multi-resistant to diseases was developed by the National Institute of Crop Science, RDA, Miryang, Korea. ‘Jinsumi’ was derived from a three-way cross of ‘Milyang165’ and F1 plant of YR16195-B-B-B-21-1/Milyang169. The pedigree of ‘Jinsumi’ was YR21999-B-B-B-17-3-1 and designated as ‘Milyang 218’ in 2005. Heading date of ‘Jinsumi’ was August 15 as mid-late maturing ecotype. ‘Jinsumi’ showed multi resistant to rice stripe virus (RSV), bacterial blight races of K1, K2, K3 and moderately resistant to leaf blast disease. The grain appearance of ‘Jinsumi’ was translucent and showed 96.6% of head rice ratio. The milled rice yield of ‘Jinsumi’ was 5.74 MT/ha at ordinary transplanting of local adaptability test. ‘Jinsumi’ would be adaptable to the plain area of Yeongnam province in Korea.
