This study was carried out to develop expressed sequence tag-Simple sequence repeat (EST-SSR) markers of brown plant hopper resistance gene originated from a rice cultivar ‘Cheongcheong’ and sensitive rice cultivar ‘Nakdong’. Total RNA extracted from the leaves of ‘Cheongcheong’ and ‘Nakdong’ were used to synthesize a cDNA library. As a result of analyzing the cDNA library, EST-SSR sites were found and the EST-SSR primer sets were developed. This study enables to provide effective marker assisted selection (MAS) methods on the selection of white-backed planthopper resistance gene originated from a rice cultivar more simply, quickly and precisely. Furthermore, using this marker’s advantage of deriving from cDNA, it is possible to identity the white-backed planthopper resistance gene.
