Abstract

A rice variety ‘Daebo’ is a japonica rice (Oryza sativa L.) with good eating quality, lodging tolerance, and resistanceto rice stripe virus (RSV) and blight bacterial disease (BB). It is developed by the rice breeding team of Yeongdeog Substation,National Institute Crop Science, RDA in 2011. This variety derived from a cross between ‘YR21247-68-1’ with good plant typeand ‘Yeongdeog35’ with good eating quality conducted in 2002 summer season. A promising line, YR23940-B-17-1-2, selectedby bulk and pedigree breeding method was designated as the name of ‘Yeongdeog51’ in 2008. After the local adaptability testwas carried out at seven locations from 2009 to 2011, ‘Yeongdeog51’ was released as the name of ‘Daebo’ in 2011. ‘Daebo’is short culm length as 63 cm and medium-growth duration. This variety is resistant to races, K1, K2, and K3 of bacterial blightand stripe virus and moderately resistant to leaf blast disease resistance. ‘Daebo’ has translucent and clear milled rice kernelwithout white core and belly rice, and good eating quality as a result of panel test. The yield potential of ‘Daebo’ in milledrice is about 5.93 MT/ha at ordinary fertilizer level of local adaptability test. This cultivar would be adaptable to middle plain,south plain, mid-west costal area, and south mid-mountainous area.
