초록
‘Keunnunjami’, a new blackish purple pigmented rice cultivar with giant embryo, is a mid-maturing ecotype developed by rice breeding team at Korea National Open University. This variety was derived from a three-way cross between ‘Heugjinjubyeo’ / ‘Suweon 425’ // ‘EM76’ in 2002 and selected by pedigree breeding method until F7 generation. Heading date of this variety is August 13 and 17 days later than that of ‘Heugjinjubyeo’ in middle plain areas. ‘Keunnunjami’ has 87.1 cm of culm height and 114 spikelets per panicle. Grain weight of 1,000-brown rice of this variety is lighter than of ‘Heugjinjubyeo’. However embryo weight is 2.82 times heavier than that of ‘Heugjinjubyeo’ on the single grain basis. C3G (Cyanidin 3-glucoside)content of ‘Keunnunjami’ is 2 times higher than that of ‘Heugjinjubyeo’. The brown rice yield of ‘Keunnunjami’ was about 4.10MT/ha at ordinary fertilizer level.
