`Superhongmi` is a new rice variety with reddish brown color developed from a crossing a high cyanidin 3-glucoside (C3G) content beeeds including Heugjinju and Suwon 425 and a big grain size breed such as Daeribbyeo. This variety heads on Sep. 5 and has 86.7 cm culm length. The fertility ratio of Superhongmi was about 81.7% and weight of 1,000-grain was about 26.8 g. The 1,000 grain weight of Superhongmi was heavier than that of Superjami. The total essential amino acid content of Superhongmi was lower than those of others. However, Superhongmi was high in tyrosine and arginine. Total polyphenol content of Superhongmi was 2 times higher than that of Heugjinju and flavonoid content was 8 times higher than that of Dongjinbyeo. In addition, hydroxy radical scavenging activity of Superhongmi was significantly higher than that of Dongjinbyeo. However, significant differences were not found in the newly breed colored rice. These results suggest that Superhongmi variety has very high value as a source of various functional food as well as stable food.
