ABSTRACT Brinjal ( Solanum melongena L.), an important solanaceous vegetable valued for its rich nutritional profile and potential health benefits, is widely cultivated in the tropical subtropical regions of world. Existing food security concerns are exacerbated due to rise soil borne pathogens, a direct consequence global warming, increasing risk crop diseases. Among these, Fusarium wilt, caused by multiple species , very serious severity persistent nature. Traditional control measures, including cultural, biological chemical approaches, have proven inadequate, highlighting need resistant cultivars. The current study focused on identifying fungal pathogen associated with brinjal employing morpho‐cultural identification, molecular characterisation sequencing DNA barcoding internal transcribed spacer (ITS) β‐tubulin pathogenicity assays isolate. oxysporum f. sp. melongenae was identified as vascular wilt brinjal. evaluated 90 diverse genotypes, released varieties local landraces brinjal, related wild resistance against screening under field conditions. Confirmatory evaluation disease reaction done artificially inoculated conditions pots. Percent incidence (PDI), area progress curve (AUDPC) stairs (AUDPS) were used identify sources understand progression patterns. Three genotypes namely Swarna Mani, S. sisymbriifolium torvum highly seven G‐17, Pink, CH‐151, Sidhasar Local, Special Muktakeshi, H‐183 Pink Shiny Medium Long found both pot Resistant exhibited distinct variations hold significant breeding programs aimed at enhancing resilience threat posed species.
