A reaction of 214 lines and varieties to BB korean race K1, resistance and moderately resistance was 33 varieties which were bred before in 1990, susceptible were 5 varieties (Milyang23, Dongjinbyeo, Sinseonchalbyeo, Changseongbyeo and Cheongmyeongbyeo). Among bred after in 1990 resistance appeared 58 varieties, 18 varieties were susceptible. Bred after in 2000 were 50 varieties appeared resistance and 5 varieties were susceptible (Manho, Goun, Jinbong, Josaengheugchal, and Manna). Accordingly most varieties bred in south korea seemed to possession resistance to BB korean race K1. As a result of whether or not having Xa1 gene of rice varieties by SNP marker appeared that 43 varieties and the other 10 lines and varieties have Xa1 gene. Varieties bred before in 1990 have 18 (62.1%) varieties out of 29 varieties possession Xa1 gene to showed resistance to BB korean race K1, 19 (47.5%) varieties bred in 1990~2000, 6 (12.8%) varieties (Boseogchal, Daepyong, Hanareumbyeo, Hopyeongbyeo, Jongnam, Kuman) bred after in 2000 seemed to possession Xa1 gene.
