The grafting in eggplant was carried out to obtain resistance sources among Solanum rootstocks against bacterial wilt and to evaluate graft compatibility of eggplant varieties with Solanum rootstocks. The experiment was laid out in Complete Randomized Design (CRD) with four replications. Bacterial wilt is one of the major problems in production of brinjal in North Eastern hill regions. The four Solanum species and two varieties were screened against bacterial wilt, among all Solanum speciesi.e. Solanum torvum and Solanum khasianum found resistant but remaining Solanum species and cultivated genotypes i.e. Pusa Shyamala and Pusa Hybrid-6 were found susceptible. The highest graft compatibility observed in plants grafted with Solanum torvum followed by Solanum surathense. The data recorded regarding the percent of bacterial wilt infection varied with rootstock used in grafting. The highest infection rate was observed in non-grafted plants (71.35%) followed by Solanum surathense × Pusa Shyamala (58.525%). The lowest infection rate was recorded in Solanum torvum × Pusa Shyamala (12.22%). Based on mean performance of the grafted plants with Solanum torvum and Solanum khasianum were found to be superior and they can be used for resistance against soil borne bacteria.
