영문 초록

The ‘Cheongun’ is a rice variety derived from a cross between ‘Suweon462’ which has translucent milled rice and medium maturity and ‘Milyang192’ that the elite line has a bacterial blight resistance and mid-late maturing property by the rice breeding team at NICS, RDA in 2012. The heading date of ‘Cheongun’ is August 13 and five days later than check variety, ‘Hwaseong’. It has 87 cm of culm length and 114 spikelets per panicle. It showed weaker cold tolerance than that of ‘Hwaseong’ while exposed to cold stress. ‘Cheongun’ showed resistance to blast disease, K1, K2 and K3 race of bacterial blight and stripe virus, but susceptible to K3a race, other viruses and planthoppers. The milled rice of this variety exhibits translucent, clear non-glutinous endosperm and short grain shape. It has similar protein content (6.7%) and amylose content (19.5%) to that of ‘Hwaseong’. ‘Cheongun’ showed better palatability index of cooked rice than that of ‘Hwaseong’. Its milled rice recovery rate is similar to those of ‘Hwaseong’. However, whole grain rate of milled rice is higher than that of ‘Hwaseong’. ‘Cheongun’ has 4.98 MT/ha of milled rice productivity in ordinary cultivation. ‘Cheongun’ could be adaptable to the middle plain area in Korea(Registration No. 5114).
