‘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).

Hyowon6, a mid-late maturing, good eating quality rice variety with multi-resistance, was developed by the rice breeding team of Pusan National University in 2013. This variety was derived from a cross between Hwayeong (as a multi-resistant parent) and Koshihikari (as a good eating quality parent). Selection by the pedigree breeding method was carried out until the F₈ generation. A promising line, JS14-12-36-8-5-3-1-1-1, was developed and designated as HY103 in 2013. This variety headed on August 22, which was 11 days later than that of Hwayeong. The culm length and panicle length of Hyowon6 was 85.7 cm and 21.1 cm, respectively. The number of panicles per hill was 14.5 and the number of grains per panicle was 101.7. The ratio of ripened grain was approximately 92% and the 1,000-grain weight was approximately 21.36 g for brown rice, which were similar to those of Hwayeong. Hyowon6 was moderately resistant to lodging and also to neck blast, leaf blight, and stripe virus. The glossiness value of Hyowon6 was 83, which was considerably higher than that of Hwayeong.

‘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’.
