Abstract
In a literature review of the world's 13 most important food crops, it is shown that 12 of these crops hybridize with wild relatives in some part of their agricultural distribution. Population genetic theory is used to predict the evolutionary consequences of gene flow from crops to wild plants, and two applied consequences of crop-to-wild gene flow - the evolution of aggressive weeds and the extinction of rare species - are discussed. Ways of assessing the likelihood of hybridization, introgression and the potential for undesirable gene flow from crops into weeds or rare species are suggested.
