Cheonga is a new japonica rice cultivar developed from a cross between Kinuhikari, Japanese japonica cultivar of good quality and clear external appearance of brown rice and Yangjuseonbal, a japonica line of good quality and ripened grain (or leaf) color, which was collected in the farmer’s field by the rice breeding team of National Institute of Crop Science, RDA.
Cheonga has about 126 days duration from seeding to heading in central lowland and mid-mountainous areas South Korea. It is about 87 cm in culm length and tolerant to lodging. It has relatively semi-erect pubescent leaf blade and slightly tough culm with good canopy architecture. This cultivar has 14 tillers per hill and 106 spikelets per panicle. It shows a little sensitivity to premature heading in the transplanting of 50 days’ old seedling. It shows similar tolerance to both heading delay and spikelet sterility due to cold stress compared with Hwaseongbyeo. This cultivar shows slow leaf senescence and low viviparous germination during the ripening stage. This variety shows susceptibility to the diseases and insect of leaf blast, bacterial blight (K1, K2, K3). stripe virus, and brown planthopper. Milled rice of Cheonga has medium short grain with translucent and clear non-glutinous endosperm. It shows similar amylose content (19.6%), and gelatinization temperature compared with Hwaseongbyeo,but good palatability of cooked rice. The milled rice yield performance of this cultivar is about 5.56 MT/ha by ordinary culture in local adaptability test for three years. This cultivar may be highly adaptable to the central plain area, middle-Southern plain and middle-western coastal areas of South Korea.
