A recent study by the University of Arkansas in the US corroborates these fears. In North Dakota, (a large GM canola growing area), 80% of the wild canola plants studied have developed herbicide resistance by crossing with GM varieties. Studies in both Canada and Japan have come to similar conclusions. Although GM Canola is not grown in Japan, transgenic oil seed rape, a close relative of canola was found in areas
