‘미광’은 1997년 중부지역 적응 고품질 품종을 육성할 목적으로 양질 다수성 계통인 SR15926-10-2-3-3-3와 익산431호를 인공 교배하여 계통육종법에 따라 육성하였다. 교배 후대에서 선발하여 육성된 우량계통에 대해 2년간(2005~2006) 생산력 검정시험을 실시한 결과, 중생종이고 도열병 및 흰잎마름병에 저항성이면서 도정특성과 쌀 외관 및 밥맛이 양호한 SR23725-55-3-2-3-2 계통을 선발하여 ‘수원514호’로 계통명을 부여하였다 ‘Migwang’ is a new japonica rice variety developed from a cross between SR15926-10-2-3-3-3 having a good canopy architecture and multiple disease resistance, and Iksan431 having a translucent milled rice and good eating-quality with a view of developing a new variety having multiple disease resistance by the rice breeding team at NICS, RDA in 2009. The heading date of this variety is August 15 and later than check variety, Hwaseongbyeo, by four days. ‘Migwang’ has 75 cm of culm length and 98 spikelets per panicle. This variety showed longer heading delay and higher spikelet sterility than those of Hwaseongbyeo while exposed to cold stress. This variety showed resistance to blast disease and bacterial leaf blight, but susceptible to rice stripe virus and planthoppers. The milled rice of this variety exhibits translucent, clear non-glutinous endosperm and short grain shape. ‘Migwang’ has better palatability index of cooked rice than that of Hwaseongbyeo. The whole grain rate of milled rice and milled rice recovery of ‘Migwang’ are higher than those of Hwaseongbyeo as 96.8% and 73.1%, respectively. ‘Migwang’ has 5.5 MT/ha in milled rice. ‘Migwang’ could be adaptable to the middle plain area, mid-western and southeastern costal areas and mid-mountainous areas in Korea.
