A Glutinous Rice Variety with Multiple Disease Resistance ‘Baegokchal’

‘Baegokchal’, a glutinous rice variety (Oryza sativa L.) with medium late maturation period, was developed by the rice breeding team of Department of Fuctional Crops, NICS, RDA in 2008. It was derived from a cross between a glutinous cultivar ‘Dongjinchalbyeo’ as glutinous cultivar and F1 of ‘YR17334Acp24/Hwayeongbyeo’ in 1998/1999 winter season. The progenies of the cross were selected by pedigree and bulk breeding method until F5 generation. As a result, a promising line ‘YR20665-20-1-2’ was selected and designated as ‘Milyang 225’ in 2006. The local adaptability test of ‘Milyang 225’was carried out at six locations during 3 years from 2006 to 2008. ‘Baegokchal’ showed tolerant to lodging with good canopy architecture as 81cm of culm length, erect leaf blades and stiff culm. It is resistant to bacterial blight K1, K2, K3 races, rice stripe virus, and leaf blast disease. The endosperm of ‘Baegokchal’ is glutinous and its whiteness is almost the same with Shinseonchalbyeo. The average yield potential of this cultivar is 5.26 MT/ha as milled rice at ordinary fertilizer level of local adaptability test. This cultivar will be adaptable to the middle and southern plain area of Korea.
