‘Neugeunsuperjami’, a late maturing and blackish purple pigmented rice cultivar, was developed from a cross between Gumjeongbyeo and Hwaseonchalbyeo. During selected by pedigree breeding method until F⁸ generation, a promising line, SR28757-22-2-4-2-1-1-2-B, was selected and advanced by late maturing and content of Cyanidin 3-glucoside. Advance line designated as the name of ‘KNOU 13’. This variety headed on August 28, 140 days to heading after sowing. The culm length and the panicle length of ‘Neugeunsuperjami’ was 91.0 cm and 20.0 cm, respectively. The number of panicle per hill was 10.5 and the number of grain per panicle was 88.6. The dehulling recovery of ‘Neugeunsuperjami’ was about 80.5% and 1,000-grain weight was about 19.7 g, heavier than that of ‘Heugjinju’. ‘Neugeunsuperjami’ has 3~5 times higher Cyanidin-3-glucoside(C3G) content compared with ‘Heugjinju’.

‘Superjami 2’, a new blackish purple pigmented rice cultivar was derived from a cross between CG2-3-5-1-6-1 (Heugjinju/Suwon 425) having a high cyanidin 3-glucoside (C3G) contents and ‘Daeribbyeo 1’ having a large grain size. During selected by pedigree breeding method until F10 generation, a promising line, SR28721-7-5-2-1-2-1, was advanced and designated as the name of ‘KNOU 6’. This variety headed on Aug. 30, so 125 days to heading after sowing and has 106 cm culm length. The panicle length of ‘Superjami 2’ was 20.4 cm. The number of panicle per hill was 8.5 ea, and the number of grain per panicles was 143.0 ea. The ratio of fertility of ‘Superjami 2’ was about 82.0% and 1,000-grain weight was about 30.1 g. The 1,000 grain weight of ‘Superjami 2’ (30.1 g) was heavier than that of ‘Heugjinju’. Also, ‘Superjami 2’ has 9 times higher C3G content compared with ‘Heugjinju’.
