I am P. Ananda Kumar again. 

As a continuation of my message (46) and in light of the comments made by Dr Samuels (60), I would like to reiterate that cross-fertilization between cultivated brinjal and its wild relatives cannot be ruled out. The chances of such events happening naturally are extremely negligible and the chances of propagation of fertile progeny are further remote. Plant breeders have spent decades to transfer desirable traits (including pest resistance) from wild relatives of crops to cultivated species (including brinjal) by various approaches such as inter-specific hybridization, inter-generic hybridization, protoplast fusions etc and the successful examples are difficult to find. If available, the penalties in terms of yield and quality are not acceptable to farmers and consumers. Several wild relatives of brinjal are resistant to Shoot and Fruit Borer (SFB) (Sarvayya, 1936). The efforts to transfer SFB resistance to brinjal were unsuccessful which shows that it is imperative to confer resistance mediated by innocuous Bt genes/proteins. The 'Fitness Advantage' to wild species of brinjal as endowed Bt is negligible because these species are already resistant to SFB. 

Reference: Sarvayya. V. 1936. The first generation of an interspecific cross in Solanums between Solanum melongena and S. xanthocarpum. Madras Agric. J., 24: 139-142.
