초록
‘Superhongmi’, a reddish brown rice cultivar, was derived from a cross between CG2-3-5-1-6-1 (Heugjinju/Suwon 425) producing blackish purple rice and ‘Daeribbyeo 1’ producing large white grains. A promising line, SR28721-7-5-2-1-2-1, was obtained using the pedigree breeding method from 2003 to 2015 and designated as ‘KNOU6R’. This variety headed on September 5, and its culm length is 94.7 cm. The panicle length of ‘Superhongmi’ is 19.8 cm. The number of panicles per hill and grain per panicle is 5.4 ea and 154.9 ea, respectively. The fertility ratio of ‘Superhongmi’ is approximately 91.0% and 1000-grain weight (TGW) is approximately 26.8 g, which is similar to that of ‘Superjami’; however, the number of panicles per hill is half of that of ‘Superjami’. The content of taxifolin and total polyphenol extracted from whole grains of ‘Superhongmi’ is 67.7 and 248 mg/100g seed weight, respectively (Registration No. 7365).
