Abstract:
Field surveys were conducted for collection of CMV virus isolates in major chilli growing areas of Telangana, depicting a wide range of symptoms ranging from mosaic, mottling, yellow discoloration, vein clearing, leaf deformation, shoe stringing or leaf narrowing, stunted growth to reduced fruit size. In an attempt to correlate the symptoms with virus concentration in different isolates, DAC-ELISA was performed on symptomatic plants and CMV was detected in majority of the isolates. It was observed that the plants with shoe stringing (typical symptom of CMV in chilli) had the highest O.D. value whereas plants with puckering had very low O.D. value. This study signifies the importance of DAC-ELISA in mass screening of chilli germplasm to determine the sources of resistance to CMV.
