Development of resistant variety of Capsicum annum L. against Chilli leaf curl virus (ChLCV), a major biotic stress in Chilli cultivation

Chilli (Capsicum annum L.) is one of the major spice crops all over the world. Among different biotic stress ChLCV is one that can ruin the crop and results in huge loss in yield. Use of pesticides proves ineffective against the virus and biotechnological approach as well as conventional breeding may be explored for the production of ChLCV. Several resistant varieties have been released by PAU, Punjab through conventional methods of plant breeding. But new strains of the virus affect the earlier variety showing resistant to old strains of ChLCV. However molecular markers have been used for the identification of susceptible and resistant markers associated with the ChLCV. Similarly, major works were reported where mapping of these markers is described and the information can be used for the development of resistant Chilli variety. Inter specific hybridization can be useful in developing resistant variety as some species of Capsicum show resistance for the virus.
