Gene stacking could lead to more weeds

(Feb. 6, 2002 – CropChoice news) – A study that English Nature commissioned found that different varieties of oilseed rape genetically modified to resist herbicides cross-pollinated with one another and, in the process, gained resistance to several herbicides. With these "stacked" resistant genes, they’ve turned into nuisance weeds.
