Abstract: An experiment was carried out to screen resistance of capsicum against S. rolfsii. Fourteen capsicum varieties/ hybrids were collected from different sources and were evaluated at College of Horticulture, Bengaluru, Karnataka during kharif 2018 to identify sources of genetic resistance against stem rot disease. The pathogen was isolated from diseased capsicum plants collected during survey at seedling and vegetative stage of the crop, purified and maintained on PDA for further screening process. Mass culture of the pathogen was prepared on sorghum grains media and inoculated at collar region of capsicum plant, at 30 days after transplanting in the earthen pots. Out of fourteen capsicum varieties/ hybrids viz., Red Inspiration and Delisha exhibited immunity against stem rot, whereas Pusa Deepti, Solon Hybrid- 2 and Nemlite expressed resistance, Green Pasarella and NS-280 moderately resistance, Green Massilia, Yellow Bachata, NS-292, NS-281, Apoorva and Asha were found to be susceptible. Hybrid Indra was highly susceptible to stem rot of capsicum.
