Serological Confirmation of Chilli (Capsicum annuum L.) Lines for Their ResistanceAgainst Cucumber Mosaic Virus

摘要

One hundred and eleven chilli lines were evaluated by mechanical virus inoculation and resistance to Cucumber mosaic cucumovirus (CMV) - chilli isolate was examined by visual examination for symptoms and confirmation by double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA). Six chilli lines viz., AVPP 0906, AVPP 1110, Aparna, Susanjoy, Phule Jyothi and ADR Driver were remained free of infection and catalogued as highly resistant. Rest of the lines exhibited characteristic symptoms like mosaic, vein banding, mottling, vein clearing, leaf distortion, rat tailling and dwarfing depending upon tested lines. Among these lines, Six lines were categorized as highly resistant, nine as resistant, three as moderately resistant, 19 as moderately susceptible and 74 as susceptible based on disease incidence (DI). These highly resistant and resistant lines could be used by breeders in developing new chilli hybrid resistant lines to CMV.
