'Hongjinju', the reddish brown coloured rice variety, was developed by the rice breeding team of National Institute of Crop Science, RDA during the period from 1990 to 2006 and released in 2007. The cultivar was derived from a cross between Suwon 383, and $SR18164F_2$, a reddish brown pigmented line. 'Hongjinju' is medium maturity with 133 days of growth duration from seeding to heading and is japonica-type with about 82 cm in culm length. 'Hongjinju' has slightly less number of tillers per hill and more spikelets of panicles than those of 'Heugjinjubyeo'. It is susceptible to leaf blast, other disease and insect pests. It shows intermediate germination ratio at low temperature and similar tolerance to leaf discolor at seeding stage and heading-delay but it is resistant to spikelets-sterility type of cold damage at maturing stage compared with 'Heugjinjubyeo'. The yield performance of this variety in brown rice is about 5.07 MT/ha and is adaptable to the central and southern plain areas of Korea.
