|Abstract: ||Chilli (Capsicum annuum L.) is an important commercial crop of India grown for its green fruits as vegetable and in ripe dried form as a spice. Though India stands first in chilli cultivation covering 45% of the world hectarage, its productivity is too low (0.9 t/ha) as compared to the world average (2.0 t/ha). There is a tremendous demand for Indian chillies in the International market, and a wide scope to improve exports considerably, provided suitable varieties as per the needs of the importing countries are produced and quality is maintained. Diseases, out of which, viral diseases are important production constraints, which contribute to lower yield and reduced fruit quality (Avilla, et al., 1997). Cent percent losses due to viruses have rendered chilli growing uneconomical, deserting the entire fields prior to harvest (Lockhart and Fisher, 1976). Several viruses have been reported, both at national (Krishnareddy and Singh, 1995) and international (Siriwong et al., 1995) levels. Although 45 viruses are known to infect peppers (Capsicum sp.) all over the world, 21 are reported to be infecting chilli in India. Among them, Chilli veinal mottle virus (ChiVMV) belonging to the potyvirus group, Cucumber mosaic virus (CMV) belonging to cucumovirus group, Chilli leaf curl virus (ChLCV) belonging to Begomovirus and Groundnut bud necrosis virus (GBNV) of Tospovirus cause major set backs in chilli production in India. Breeding for virus resistance is reviewed in the chapter.|
