This study was conducted to develop a japonica-type rice cultivar with brown planthopper (BPH) resistance using DNA
markers. A doubled haploid (DH) population consisting of 120 pure-lines was established by anther culture of F1 hybrids between
‘Samgang’, a Tongil type BPH resistance cultivar, and ‘Nagdong’, a japonica cultivar. To determine the map position of genes
responsible for BPH resistance in rice, a genetic map was constructed based on 120 DH lines. A total of 162 molecular markers
were classified into 12 linkage groups, covering 1,884 Kosami centimorgan (cM) with an average of 11.6 cM. Five QTLs
(qBPR3, qBPR6, qBPR7, qBPR8, and qBPR12) associated with BPH resistance were identified and mapped on chromosomes
3, 6, 7, 8, and 12, respectively, using the genetic map constructed in this study. To analyze the relationship between BPH
resistance and agronomic traits, a total of eight QTLs related to the agronomic traits were detected on 12 rice chromosomes.
In an analysis of relationships, three QTLs (qBPR3, qBPR7, and qBPR8) showed a linkage with tested agronomic traits. A QTL
(qBPR3) located on chromosome 3 (RM282-3023) was closely linked to culm length (qCL3). The QTL (qBPR8) for BPH
resistance on the short arm of chromosome 8 also overlapped the region detected in culm length (qCL8).
