"Oraebyeo" is mutation of a high quality japonica cultivar, Ilpumbyeoa new japonica rice(Oriza sativa L.) cultivar developed from by N-methyl-N-nitrosourea(MNU) treatment on fertilized egg cell by the rice breeding team of Gangwon Provincial Agricultural Res. & Ext. Service in 2006. This variety heads 20 days earlier than Ilpumbyeo and similar to that of Odaebyeo an early maturing leading cultivar of northern plain area of Korea. Compared with Odaebyeo has a good semi-erect plant type with lodging tolerance due to much shortened plant hight(l2cm shorter than Odaebyeo). Oraebyeo has similar panicle number with Odaebye where as it has more spikelets per panicle. However, this variety less the ratio of ripened grains and 1,000 grain weight than those of Odaebyeo. The yield performance of this cultivar in milled rice was about 5.09MT/ha in local adaptability test conducted for three years 2002-2004 and 5.51MT/ha in the demonstration plot of farmer's field.

“Yeonganbyeo”, a new japonica rice variety (Oryza sativa L.), is a mid- maturing ecotype with high lysine content in kernels that was developed by the rice breeding team of National Yeongnam Agricultural Experiment Station (NYAES) in 2001 and released in 2002. This variety was originated from the single cross of Milyang 122/YR13616 Acp1 (in 1992/1993 winter) and was selected by means of a mixed method of bulk and pedigree breeding. The pedigree of “Yeonganbyeo” was YR15815-B-B-B-30 and designated in 1998 as “Milyang 164”. It has about 83cm in culm length with lodging tolerance. This variety is resistant to bacterial leaf blight (K1, K2, K3), stripe virus, and moderately resistant to leaf blast disease. Milled rice kernels of “Yeonganbyeo” has high lysine content of 4.31% (ratio of amino acid components in total protein), a clear translucent with non-glutinous endosperm and clear in chalkness and good at eating quality by pannel test. The yield potential of “Yeonganbyeo” in milled rice is about 5.45 MT/ha at ordinary fertilizer level of local adaptability test. This cultivar would be adaptable to the southern plain of Korea.

This study was carried out to develop a prom ising japonica rice variety resistant to brown planthopper(Bph) through marker-assisted selection(MAS) and backcross breeding methods. 'Milyang 64' which is known as resistant japonica variety to Bph used as a

Areumbyeo', a second generation Tongil-type rice variety (Oryza sativa L.), has been developed at National Yeongnam Agricultural Experiment Station (NYAES) from 1983 to 1999 and released in 2000. A single cross between YR3299-34-2-2 and Suweon 318 (was co

Nonghobyeo', was derived from a mutant of Milyang 95, by pure line selection method, which was developed from the single cross between Chukei 1016 and Milyang 79, by the rice breeding team of National Yeongnam Agricultural Experiment Station (NYAES) in 19

Mananbyeo was developed from a three way cross ilyang110/Yeongdeog7//Milyang110 in 1999. It has short growing duration about 71 days from seeding to heading and short culm length of 75 cm. It has almost similar number of panicles per hill , spikelets per

Sujinbyeo', a new mid-late maturing japonica rice variety (Oryza sativa L.), was developed by the rice breeding team of National Yeongnam Agricultural Experiment Station (NYAES) in 1999 and released in 2000. This variety originated from a three way cross
