This study was carried out to select DNA markers closely linked to brown planthopper (BPH) resistance gene originated from a rice cultivar ‘Cheongcheongbyeo’. For the mapping of resistant gene to BPH, a doubled-haploid (DH) population was developed by anther culture of F₁ plants from a cross ‘Cheongcheongbyeo/Nagdongbyeo’. In BPH bioassay and marker screening for the DH population, the segregation of resistant and susceptible plants to HPH fitted to a 1:1 ratio. A total of 310 RAPDs of 520 markers showed polymorphism in parental survey using ‘Cheongcheongbyeo’ and ‘Nagdongbyeo’. In the analysis of relationship between BPH resistance and marker pattern for 40 DH lines, the OPE16 produced a specific dominant fragment, 700 bp, which was closely linked with BPH resistance gene of ‘Cheongcheongbyeo’. Based on the linkage analysis using 7 markers, BPH resistance of ‘Cheongcheongbyeo’ was mapped on chromosome 12, which was closely linked with OPE16₇₀₀ at a distance of 4.6 cM.
