    Abstract. Brown planthoppers (BPH, Nilaparvata lugens Stål) is considered as the main pest in rice plantation in Indonesia, including Sumatra Island. An Integrated Pest Management (IPM) by using resistant varieties is one of the best approaches to control the pest. Local germplasm offers source of gene for the development of resistant varieties. This study was subjected to observe the resistance of local rice varieties originated from Sumatra Island, Indonesia to BPH. The evaluation was carried out using seedling test method. A total of 85 rice accessions of IAARD-ICABIOGRAD Gene Bank collected from Sumatra Island were assessed in a randomized experimental design with three replications. IR 42 and IR 64 were used as susceptible check, whereas PTB 33 was used as resistant check for BPH. Scoring and determination level of resistance were conducted according to Standard Evaluation System of IRRI. The results showed that 5 and 14 rice accessions were highly resistant and resistant to BPH, respectively. There was no correlation observed between the level of BPH resistance and the origin of the accessions. The existences of some highly resistant local rice accessions identified in present study are potential sources for the development of BPH resistant varieties to support the implementation of IPM and agricultural development in the region.
