- Abstract
The ‘Cheongbaekchal', a glutinous rice (Oryza sativa L.) cultivar, was developed by the rice breeding team of National Institute of Crop Science, RDA, in 2010. It was derived from a cross between SR20261-5-4-10 and ‘Jinbuchal' which is an extremely early maturing variety with northern alpine area adaptability. The heading date of ‘Cheongbaekchal' is July 27 that is 4 days earlier than that of ‘Odae’. This cultivar has 68 cm of culm length, 14 tillers per hill and 80 spikelets per panicle that is more than that of ‘Odae’. This variety showed similar cold tolerance to ‘Odae’ while exposed to cold stress. This variety showed resistance to blast disease but susceptible to bacterial blight, stripe virus and planthoppers. The milled rice of this variety exhibits opaque and glutinous endosperm and short grain shape. This variety has lower Alkali digestive value (5.5) than that of ‘Odae’. The dehulling recovery rate of ‘Cheongbaekchal' is lower than those of ‘Odae’. The milled rice yield performance of ‘Cheongbaekchal' was 5.35 MT/ha in local adaptability test for three years. ‘Cheongbaekchal' is adaptable to northern plain and mid-mountainous, southern alpine and north-eastern coastal area of Korea.
