다수성 고품질 흑색 찹쌀 신품종 ‘청풍흑찰’

Abstract

‘Cheongpungheukchal’, a new blackish pigmented glutinous rice variety , was developed by the rice breeding team of Chungbuk Agricultural Research and Extension Services in 2009. This cultivar was derived from a cross between ‘Shindongjin’ as grain quality source and ‘Heugseonchal’ as black glutinous and aromatic source. The donor parent, ‘Sindongjin’,had been backcrossed one time with recurrent parent ‘Heugseonchal’ and selected by the pedigree breeding method until F6generation. As a result, a promising line, CBR12-9-3-1, was advanced and designated as the name of ‘CBR12 L8’ in 2006. The cultivar headed on August 23 in the test of local adaptability and had 65 cm culm length. This cultivar had about 16 tillers per hill and 108 spikelets numbers per panicle. Ripended grain ratio was about 78.5% and 1,000 grain weight was 23.5 g in brown rice. It is moderately resistant to leaf blast but susceptible to other disease and insect pests. It has higher anthocyanin content compared to blackish pigmented check cultivar ‘Heugseonchal’. The yield performance of brown rice was 5.80 MT/ha in local adaptability test for three years. ‘Cheongpungheukchal’ is adaptable to middle plain and southern mid-mountainous area under ordinary cropping system in Korea.
