The probability of crop-to-wild gene flow depends on the geographic distribution of crops and their wild relatives. In this context, caution has been advised in relation to the release of transgenic crops into their centres of origin, i.e. the geographical regions in which they were domesticated, and where wild relatives and/or weedy forms persist. In countries with high plant biodiversity like India, where almost 400 species of crop wild
relatives are found, this is a relevant approach. (Correspondence)
