The impact of transgenic rape in cultivation systems : a study of gene flow.
Abstract
Preliminary results are provided of an experiment into gene flow among transgenic herbicide-resistant rape and black mustard [Brassica nigra], white mustard [Sinapis alba] and wild radish [Raphanus raphanistrum], started in 1995 at Toulouse, Dijon and Chalons, France. Three separate treatments of either glyphosate, glufosinate or an oxynil herbicide were applied to randomized plots. The Toulouse site was characterized by large numbers of cruciferous weeds [Brassicaceae] both inside and outside of the rape plots, whilst at the other sites, cultivated plots were generally weed free. Seeds of weedy relatives collected both from within and outside rape plots are currently being tested for their resistance to the 3 groups of herbicides.
