Abstract
<p>Fitness of hybrids between genetically modified (GM) crops and wild relatives influences the likelihood of ecological harm. We measured fitness components in spontaneous (non-GM) rapeseed × <em>Brassica rapa</em> hybrids in natural populations. The F<sub>1</sub> hybrids yielded 46.9% seed output of <em>B. rapa</em>, were 16.9% as effective as males on <em>B. rapa</em> and exhibited increased self-pollination. Assuming 100% GM rapeseed cultivation, we conservatively predict < 7000 second-generation transgenic hybrids annually in the United Kingdom (i.e. ∼20% of F<sub>1</sub> hybrids). Conversely, whilst reduced hybrid fitness improves feasibility of bio-containment, stage projection matrices suggests broad scope for some transgenes to offset this effect by enhancing fitness.</p>
