Abstract: Eggplant or brinjal (Solanum melongena L.) is an important vegetable crop grown in tropical and subtropical parts of world including India. Bacterial wilt (Ralstonia solanacearum) is one of the major constraints in brinjal production in these regions and cause the yield loss upto 100 percent under favorable climatic conditions. Due to lack of information about the host, pathogen and environment, limited success is reported to control this disease. Hence, to identify the stable source of resistance, 30 accessions of eggplant (Solanum melongena L.) were screened in a sick plot for bacterial wilt (Ralstonia solanacearum) resistance at Indian Institute of Horticultural Research, Hessaraghatta, Bengaluru. Among 30 genotypes, IIHR-500A showed maximum resistance with no wilting symptom while eight genotypes namely IIHR-127, IIHR-575, IIHR-584, IIHR-667A, IIHR-766A, IIHR-817, IIHR-874, IIHR-882 showed resistant reaction with good yield potential. Three genotypes viz., IIHR 438-2, IIHR-618, IIHR-766 showed moderately resistant reaction and another three IIHR-576, IIHR- 583 and IIHR-798 moderately susceptible reaction. The genotypes IIHR-574, IIHR-692, IIHR-793 and IIHR-857 were susceptible to bacterial wilt and 11genotypes namely IIHR-228, IIHR- 534, IIHR-569, IIHR-571, IIHR-632, IIHR-711, IIHR-694, IIHR-812, IIHR-813, IIHR-880, IIHR-881 were highly susceptible.
