304 accessions of eggplants were identified and evaluated for resistance against bacterial wilt by artificial inoculation at the seedling stage.The results showed that 10 of them were immune(I),51 highly resistant(HR),35 were resistant(R),32 were moderately resistant(MR),and 176 were susceptible(S or HS),representing 3.3%,16.8%,11.5%,10.5% and 57.9% of the plant materials tested.The wild species and relatives of eggplant Solanum sisymbriifolium and S.torvum were highly resistant to bacterial wilt.We obtained 4 somatic hybrid accessions of S.melongena with S.torvum and S.aethiopicum group aculeatum,which were highly resistant to bacterial wilt.The resistance to bacterial wilt in eggplant was controlled by multigene.
