Paul Rylott of Biotech Company Aventis argues many herbicide tolerant crops are created through conventional breeding, "GM crops are no different." He suggests that crossing between conventional varieties could have the same result.

But Brian Johnson of the political advisory group English Nature notes that resistance bred into plant varieties tends to be much weaker and there is no evidence of 'superweeds' having been created in this way.

While the M.J. Crawley et al assert in a paper published by the Journal Nature titled Biotechnology: Transgenic crops in natural habitats" (v409-p682), "[That] in no case were the genetically modified plants found to be more invasive or more persistent than their conventional counterparts."

Hmm. Makes one wonder just how Mr. Johnson defines "superweed", eh?
