Online published on 5 February, 2019. Abstract Fifty eight rice genotypes comprising of released varieties, elite breeding lines and genotypes obtained from different screening nurseries were evaluated against brown plant hopper under glasshouse conditions at Punjab Agricultural University, Ludhiana during kharif 2015 and kharif 2016. Based on two years screening, twelve entries showed resistant to moderately resistant reaction. From these, three genotypes, RP2068-303, RP2068-295 and KAUM182-1 were found to be resistant while nine other genotypes, CR3006-8-2, PAU5815-56-2, PAU5815-39-3, CT18139-8-5-1-5-1-1-M, PAU6002-32-1, PAU5815-39-2, PAU6002-32-4, IR71033-121-15-B and IR82858-B-B-2 showed resistant to moderately resistant reaction during two years of screening trial. The potential donors identified in the present study are expected to be a valuable source of BPH resistance.
