Sweet pepper is commonly known as capsicum, bell pepper and Shimla mirchi. Under protected cultivation widely grown due to higher productivity and economic feasibility. Diseases of viral nature affect the crop production significantly both in terms of yield and quality. To know the incidence of viral diseases and prevalence of vector population fourteen capsicum hybrids were screened during kharif 2018 and rabi 2018-19. None of the hybrids were found to be resistant during the both the seasons. However, During kharif 2018, six hybrids viz., Maxibell, Shristika, SV1865PB, Asha, Arka Gaurav and Arka Basanti were found to be moderately susceptible for leaf curl disease and for mild mottle disease, hybrids Arka Gaurav and Arka Basanti recorded moderately resistant reaction. Results of rabi 2018-19 season revealed that, hybrids Shristika, SV1865PB, Asha, Indra, Arka Gaurav, Arka Basanti, 35-160-R2 and NSX 8 found to be moderately susceptible for mosaic disease. The symptoms observed during screening included mosaic and mottling, yellow discoloration, vein clearing, leaf deformation and narrowing, stunted plant growth, reduced fruit setting and light green colour mottling symptoms on fruits
