This experiments were carried out to know the response to Brown Planthopper(BPH) resistance genes at rice seedling stage using Biotype 1 for develoment of resistant cultivars. Varieties with Bph1, Bph3 and Bph18 genes showed a very strong resistance response, Bph2, Bph6, bph7 and Bph9 genes exhibited moderate resistance. bph5 and bph8 gene retention varieties and Nampyeongbyeo showed a very weak sensitivity in response to BPH. After 72 hours, Nampyeong(no gene) and IR72(Bph3 gene) were showed a feed-preference 690% and 0%, respectively. Results of Antixenosis and seedling resistance response to BPH were grouped into similar by specific resistance genes. Ten days after inoculation, BPH survival rate of vareities with resistance genes were below 30%, whereas Nampyeongbyeo was more than 70%. The results showed that Bph3 and Bph18 genes are highly resistant response against BPH, these genes are very useful for improve the rice cultivars with various resistance genes
