J. Allainguillaume, M. Alexander, J. M. Bullock, M. Saunders, C. J. Allender, G. King, C. S. Ford, M. J. Wilkinson. (2006). Fitness of hybrids between rapeseed Brassica napus and wild Brassica rapa in natural habitats. Molecular Ecology, 15 (4) 1175-1184. RAE2008 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 F1 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 F1 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.
