Transgenic Approaches For Development Of Highly Tolerant Tomato For Leaf Curl Virus (Tolcv)

Transgenic approaches provides solutions to the problems, which cannot be solved by conventional breeding methods. Tomato leaf curl virus disease is very important disease of Tomato particularly in winter and summer season. Highly tolerant Tomato were developed using T-rep gene construct. High level of tolerance for TOLCV and inheritability of the transgene were observed following challenge inoculation with the viruliferous White- flies. The mechanism of resistance appears RNAmediated, since the plants carried the untranslatable antisense rep gene.
