벼 중생 고품질 내도복 복합내병성 중간모본 ‘중모1009호’

Abstract

A new rice variety ‘Jungmo1009ho’ is a japonica rice (Oryza sativa L.) with lodging tolerance and resistance to rice stripe virus (RSV) and blight bacterial disease (BLB) and good eating quality. It is developed by the rice breeding team of Yeongdeog Substation, National Institute Crop Science, RDA in 2009. This variety was derived from a cross between ‘Iksan443’with good grain quality and ‘Milyang165’ with lodging tolerance conducted in 1999 summer season. A promising line, YR22207-5-3-1-3, selected by pedigree breeding method was designated as ‘Yeongdeog48’ in 2006. After the local adaptability test was carried out at nine locations from 2007 to 2009, ‘Yeongdeog48’ was released as the name of ‘Jungmo1009ho’ in 2009. ‘Jungmo1009ho’ is very short culm length as 61cm and medium-late growth duration. This variety is resistant to races, K1, K2,and K3 of bacterial blight and stripe virus and moderately resistant to leaf blast disease with durable resistance, and also has tolerance to unfavorable environment such as cold and dried wind. ‘Jungmo1009ho’ has translucent and clear milled rice kernel without white core and belly rice, and good eating quality as a result of panel test. The yield potential of ‘Jungmo1009ho’ in milled rice is about 5.47 MT/ha at ordinary fertilizer level of local adaptability test. This cultivar would be adaptable to east-south coastal cold salty wind and south mid-mountainous area
