‘Bodrami’ is a brown rice cultivar suitable for cooking, developed by crossing ‘Hwaseong’ and ‘Congsengla’ cultivars at Rural Development Administration, Korea, in 2003. Cooked brown rice of ‘Bodrami’ naturally has a soft texture, and after 24 hours of warm treatment, it maintained its soft texture and it was evaluated that the taste and texture of cooked brown rice were better than that of another rice cultivar. ‘Bodrami’ is a mid-maturing rice cultivar. The average heading date in ordinary planting was August 11^th in Suwon, Korea, which also exhibits strong to blast leaf and rice stripe virus, and brown rice yield of ‘Bodrami’ had a yield of 5.56 MT/ha in ordinary planting. The advantages of eating brown rice are high intake of GABA (which is excellent for controlling blood), γ-oryzanol (which is good for Antioxidation), rice embryos (rich in fiber), and rice bran (rich in minerals). Another advantage of ‘Bodrami’ is that, compared to glutinous rice varieties (which is a higher glycemic index), it has a lower glycemic index and a smooth texture. The consumption of white rice has been decreasing recently, while interest in brown rice has been increasing as a consequence of these advantages. ‘Bodrami’ was developed in response to recent changes in consumption preferences.

‘Asemi1’ is a rice variety derived from a cross between ‘IR71667’, which has a Jinmibyeo background with a long basic vegetative phase, and ‘IR77863’, which has a Shinunbongbyeo background with a high yield and early maturity, by the rice breeding team at NICS, RDA, in 2014. The heading date of ‘Asemi1’ is July 29, 14 days earlier than that of the check variety ‘Hwaseong’. It has a culm length of 84 cm and 110 spikelets per panicle. ‘Asemi1’ is resistant to blast disease, but susceptible to other viruses and planthoppers. The milled rice of this variety exhibits translucent, clear non-glutinous endosperm and a short grain shape. The protein content (7.3%) was higher than that of ‘Hwaseong’, and the amylose content (19.6%) was similar to that of ‘Hwaseong’. The milled rice recovery rate of ‘Asemi1’ was similar to that of ‘Hwaseong’. However, the head rice rate of ‘Asemi1’ was lower than that of ‘Hwaseong’. The milled rice yield of ‘Asemi1’ was 5.92 MT/ha, which was higher than that of ‘Hwaseong’ in ordinary cultivation. ‘Asemi1’ was suitable for adaptation to a wide region of tropical Asia (Registration No. 6809).

‘Jinkwang’, a japonica rice variety, was developed by a cross between ‘Hopum’ (IT23527) and the F1 hybrid of ‘Unkwang’ (IT217814) and ‘Koshihikari’ (IT157335) by the rice breeding team at NICS in 2016. ‘Unkwang’ shows an early maturity and high yield and ‘Koshihikari’ is a high-quality variety. The growth duration of ‘Jinkwang’ in the paddy field was 114 days in the middle plain region in Korea, which was six days later than that of ‘Jopyeong’.

The viviparous germination rate of ‘Jinkwang’ was 28.3%. ‘Jinkwang’ showed resistance to blast and bacterial blight (K1, K2, and K3 races); however, it was susceptible to stripe virus, dwarf and black-streaked dwarf viruses, and plant hoppers. The milled rice grains of ‘Jinkwang’ showed an excellent palatability index (0.42) and lower protein content (6.2%) than that of ‘Jopyeong’. The grain milling characteristics were better than those of ‘Jopyeong’, especially in terms of brown/rough rice ratio and milled/rough rice ratio (75.9%). ‘Jinkwang’ showed a milled rice productivity of 5.91 MT/ha at eight sites under ordinary cultivation conditions. (Registration No. 7318).

“Samkwang1,” a japonica rice variety, was developed as a cross between “Samkwang” and F1 of Suwon152 (IT008283), which has a medium maturing and lodging resistance and Samkwang (IT284608), a high quality variety with bacterial blight resistance and mid-late maturing property by the rice breeding team at NICS in 2015. The heading date of “Samkwang1” was August 8 in the middle plain area, which was 2 days early than that of “Hwaseong.” “Samkwang1” had a culm length of 77 cm, which was 7 cm shorter than that of “Hwaseong,” and it had 128 spikelets per panicle. The viviparous germination rate of “Samkwang1” was 2.1%. “Samkwang1” showed resistance to blast, bacterial blight (K1, K2, and K3 race) and stripe virus, but was susceptible to the K3a race of bacterial blight, dwarf and black streak dwarf viruses, and plant hoppers. The milled rice of this variety exhibits translucent and medium short grains. The cooked rice grains of “Samkwang1” have an excellent palatability index (0.35) and lower protein content (6.2%) than that of “Hwaseong.” The characteristics related to grain milling were better than those of “Hwaseong,” especially the head rice milling recovery ratio and head rice ratio (94.2%). “Samkwang1” showed 5.62 MT/ha of milled rice productivity at 11 sites under ordinary cultivation conditions (Registration No. 6798).

Cheongpum’, a japonica rice variety, was developed from a cross between Yeongdeog45 and ‘Samkwang’ by the rice breeding team at NICS in 2015.
