Five wild Solanum species were screened against dry root rot disease in glass house condition with commonly cultivated brinjal as control. The disease was scored at different day’s interval on 30th, 45th and 60th days after planting (DAP). Among the wild species screened and evaluated the species S. torvum was observed without any disease incidence i.e (0). The least per cent of disease incidence was observed in S. incanum (38.60%) which was followed by S. xanthocarpum (42.80%), S. viarum (64.20%) and CO2 (78.50 %) susceptible check at 30 DAP. Secondary metabolites were analysed from both wild and control plants. Based on the per cent disease incidence values S. torvum was graded as ‘Resistant’ against M. phaseolina and can be recommended as a best rootstock for brinjal under varying climatic condition especially where the dry climate prevails.
