ABSTRACT
Chilli is known to be affected by forty five viruses. Twenty four of them have been reported to occur naturally and rest can infect on artificial inoculation. Among the twenty four viruses reported to occur naturally on chilli, eleven viruses have been reported from India. Among all, the chilli leaf curl virus is the most destructive virus in terms of incidence and yield loss. In severe cases 100 percent losses of marketable fruit have been reported. Chilli leaf curl locally known as murda is a most destructive disease of chilli in India. However, the viral nature of the disease has not been proved experimentally until Ashrafi Jha from IARI established this by grafting, later it was proved that leaf curl of chilli is caused by tobacco leaf curl virus (Ruga tabaci) which is transmitted by vector B. tabaci. The diseases caused by begomoviruses are easily recognized by their distinctive symptoms in plants infected with these viruses. The symptoms are broadly of three types: a) vein yellowing, b) yellow mosaic and c) leaf curl. Control of ChiL CV viruses by chemicals or cultural management practices has not been very effective. The planting of resistant cultivars offers the best way to control these viruses. A number of sources of virus resistance have been reported in wild and cultivated lines and several virus-resistant lines have already been released. Many multiple virus-resistant varieties have been developed at Punjab Agricultural University, Ludhiana. Important multiple resistant lines are Perennial, BG-1, Lorai, and Punjab Lal. Weeds act as potential sources of begomoviruses, several weed families particularly Malvaceae have been found to harbor viruses.
Key words: Chilli leaf curl, begomo viruses and B. tabaci and management.
