Abstract: King chilli (Capsicum chinense J.) also known as “Umorok” in Manipur or “Naga chilli” in Nagaland or “Bhut Jolokia” in Assam is the most important spice crop of North East India. It is one of the hottest chillies in the world. In spite of its importance, cultivation of king chilli is limited by numbers of biotic and abiotic factors. Among the various biotic factors, viral disease complex is considered to be the most significant, destructive and devastating factors. Various surveys were conducted at different king chilli growing areas of Manipur and its neighbouring states to record the prevalence of viral complex in order to characterize the associated viruses. Varying kind of symptoms ranging from leaf mottling, puckering shoe- string, vein banding, severe curling, mosaic and smaller leaf lamina were observed under field conditions. Out of 79 samples tested for four viruses (Cucumber mosaic virus: CMV; Chilli veinal mottle virus: ChiVMV; begomoviruses and tospoviruses) in PCR or RT-PCR using specific primers targeting CP regions of respective viral genome, 30 samples were found positive for CMV (37.97%) and 17 samples for ChiVMV (21.51%) were found positive. Further, it was also observed that 3 samples were found mix infection.
