중생 고품질 내도복 내병성 벼 품종 ‘진보’

Abstract

A new rice variety ‘Jinbo’ is a japonica rice (Oryza sativa L.) with good eating quality, lodging tolerance, and resistance to rice stripe virus(RSV) and bacterial blight disease(BB). It was developed by the rice breeding team of Yeongdeog Substation, National Institute of Crop Science(NICS), RDA in 2009. This variety was derived from a cross between ‘Yeongdeog26’ with good grain quality and wind tolerance and ‘Koshihikari’ with good eating quality in 1998 summer season.. A promising line, YR21324-56-1-1, selected by pedigree breeding method, was designated as the name of ‘Yeongdeog45’ in 2005. After the local adaptability test was carried out at nine locations from 2006 to 2008, ‘Yeongdeog45’ was released as the name of ‘Jinbo’ in 2009. ‘Jinbo’ has short culm length as 74cm and medium maturating growth duration. This variety is resistant to K_1, K_2 and K_3 races of bacterial blight and stripe virus and moderately resistant to leaf blast disease with durable resistance,and also it has tolerance to unfavorable environments such as cold and dried wind. ‘Jinbo’ has translucent and clear milled rice kernel without white core and white belly rice, and good eating quality as a result of panel test. The yield potential of ‘Jinbo’in milled rice is about 5.65 MT/ha at ordinary fertilizer level in local adaptability test. This cultivar would be adaptable to middle plain, mid-west costal area, east-south coastal area, and south mid-mountainous area.
