Abstract

Nilaparvata lugens. A doubled-haploid (DH) population produced from a cross between a Tongil-type cultivar Samgangbyeo anda japonica cultivar Nagdongbyeo was used for the analysis. Relationship between BPH resistance and DNA marker patterns wasanalysed by bulked-segregant analysis (BSA). Eleven primers of 520 RAPDs showed polymorphic band between resistant and sus-ceptible bulk DNA. Of these, a primer, OPE18923, was selected to be tightly linked (4.4 cm) to the resistance. The OPE18923 primerswould be applicable as a selectable marker to breeding program for BPH resistance in rice.
