A glass house experiment was conducted at Department of Entomology, IGKV, Raipur (Chhattisgarh), during 2014-15 to evaluate different rice genotypes for brown planthopper (BPH) resistance. A total of 392 rice genotypes were evaluated, of which 58 were from IRRI, 78 were aromatic types and rest 256 represented the local germplasm. Of 58 rice genotypes from International Rice Research Institute six viz. Ptb 33 (0.17), IR 03A159 (0.45), IR 09N522 (0.66), IR 07A179 (0.67), IR 08N136 (0.90) and IR 09N538 (0.91), were found to be highly resistant to BPH while 32.7% were resistant. Among the 78 aromatic rice genotypes tested for BPH reaction, eight were identified as resistant viz. Lua Nhe Den (1.66), Bong Cay (1.67), KDML 105 (1.94), UPR-2828-7-2-1 (2.39), IR 754286-3 (2.56), Improved Pusa Basmati 1 (2.79), Shyamjeera (3.00) and Longku Labat (3.00), while six as moderately resistant and rest as susceptible. In another set of experiment conducted with 265 rice germplasm, only 11.32% exhibited resistance to BPH, lowest plant damage score being recorded with 579004 (1.40), followed by 464205 (1.50) and 578983 (1.50) while 55 were moderately resistant and rest were susceptible.
