Field trials in India suggest that genetically modified crops have far greater benefits in developing countries, than the developed countries for which they were designed.



The farm trials of cotton genetically modified to produce a bacterial toxin produced increases in yield of up to 80 per cent, compared with non-GM counterparts. This is much greater than the improvement seen in developed countries where yields are boosted by less than 10 per cent, say the researchers.



While many groups have opposed GM crops, others argue there is a moral case for introducing GM technology to developing countries, to help tackle poverty and hunger.
