Abstract
'Manmibyeo', a new japonica rice cultivar, is a mid-late maturing ecotype cultivar developed by the rice breeding team of Department of Functional Crop, NICS, RDA in 2002. This cultivar was originated from the cross between 'Milyang 95' and $F_1$ of the cross between 'Bukrukbanna' and 'Milyang 95' in 1990/1991 winter season. It was selected by pedigree breeding method until F6 generation, and a promising line, YR14545-9-2-3-4, was advanced and designated as 'Milyang 162' in 1996. The local adaptability test of 'Milyang 162' was carried out at seven locations during 3 years in 1997, 1998 and 2002. It has about 86cm culm length and is lodging tolerant. This cultivar is susceptible to bacterial blight ($K_1$, $K_2$, $K_3$) and stripe virus, and moderately resistant to leaf blast disease. Milled rice kernels of 'Manmibyeo' is translucent with low amylose content in endosperm, clear in chalkiness and good at eating quality in panel test. The yield potential of 'Manmibyeo' in milled rice was about 4.46 MT/ha at ordinary fertilizer level in local adaptability test. This cultivar would be adaptable to the southern plain of Korea.
