This study was carried out to investigate the effects of addition ratio of reddish-brownpigmented rice(Suwon 451) on the color difference, mechanical characteristics and gelatinization degree, sensory characteristics of Seolgid-deok. As the amount of reddish-brown pigmented rice was increased, redness was getting increased, lightness and yellowness was getting decreased. In hardness, adhesiveness, cohesiveness and chewiness, as the amount of pigmented rice was increased, was getting decreased and springiness was getting increased. As the amount of pigmented rice was increased in Seolgiddeok, gelatinization was getting increased. In sensory evaluation, quality characteristics of Seolgiddeok with 20% reddish-brown pigmented rice added was better in color, sweetness and overall quality than those of Seolgiddeok without reddish-brown pigmented rice.

'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.
