The development of biotypes and existence of variability in Brown planthopper population always demands for the identification of new sources of resistance from time to time. However, the presence of desirable quality and yield traits in the genotypes along with source of resistance to BPH will be an added advantage. Screening was carried out with 39such promising rice genotypes and three checks following standard seed box technique. The test revealed 17 genotypes to be moderately resistant with damage score ranging between 3.6 -5.0. Among 17 genotypes, KNM 2305 and RNR 21571 recorded lowest damage score of 3.6. Further investigations on presence of other mechanisms of resistance such as antixenosis, antibiosis and tolerance needs to be studied to identity the best genotype among the 17 genotypes that could to be used for developing BPH resistant / tolerant variety with desirable yield and quality traits.
