The Jungsaenggold is a japonica rice variety developed from a cross between Yeongdeog34 which has translucent milled rice and good milling properties and F1 of Yumetsukushi and Saesangju that the varieties have a good canopy architecture, cold tolerance and early maturing property by the rice breeding team at NICS, RDA in 2011. The heading date of this variety is August 8 and four days earlier than check variety, Hwaseong. Jungsaenggold has 78 cm of culm length and 113 spikelets per panicle. This variety showed similar cold tolerance to ‘Hwaseong’ while exposed to cold stress. This variety showed resistance to blast disease and stripe virus, but susceptible to bacterial leaf blight and planthoppers. The milled rice of this variety exhibits translucent, clear non-glutinous endosperm and short grain shape. Jungsaenggold has better palatability index of cooked rice than that of Hwaseong because of lower protein content (6.2%) and amylose content (17.2%) than that of Hwaseong. The whole grain rate of milled rice is higher than that of Hwaseong and milled rice recovery rate of Jungsaenggold is similar to those of Hwaseong. Jungsaenggold has 5.05 MT/ha of milled rice productivity in ordinary cultivation and 5.51 MT/ha in early cultivation. Jungsaenggold could be adaptable to the middle plain area in Korea.
