Background
Genetic and breeding research on the natural resistance system against a serious insect pest of rice, brown planthopper (BPH), Nilaparvata lugens Stal, begun in the mid-1960s. Twelve BPH resistance genes have so far been identified. A BPH resistance gene, Bph10, from Oryza australiensis was first assigned to rice chromosome 12 (Ishii et al. 1994). Later, Bph1from an Indian variety, Mudgo, and bph2 from an IRRI breeding line, IR1154-243, were also mapped on chromosome 12 (Hirabayashi and Ogawa 1995; Murata et al. 1997, 1998).Bph9, is a dominant brown planthopper resistance gene, locating on the long arm of rice chromosome 12. Bph9 was first identified in a Sri Lankan variety by Nemoto (Nemoto et al. 1989). Then map position of BPH turned out to be on the long arm of rice chromosome 12, which is discovered by Murata in 2000 ( Murata et al. 2000).
