Abstract:
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 × Brassica rapa hybrids in natural populations. The F 1 hybrids yielded 46.9% seed output of B. rapa , were 16.9% as effective as males on B. rapa 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 1 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.
