초록
‘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 culm length of ‘Jinkwang’ was 62 cm, which was 13 cm shorter than that of ‘Jopyeong’. The panicle of ‘Jinkwang’ was composed of 100 spikelets. 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).
Abstract
