 Over 400 experts from around the world are at the IAEA headquarters to take part in the International Symposium on Plant Mutation, Breathing and Biotechnology. Nuclear techniques can be used to generate changes in the plant's DNA and produce varieties that improve their yield and quality. The scientific conference is a unique opportunity to network, exchange ideas, information and make the technology even more effective, more productive. Plant Mutation Breeding has made a significant contribution to food security across the globe. A large fraction of the population in the world is using products that have been derived from mutation breeding. The example I'd like to give is Centenario, which was a barley variety that was released and produced using mutation breeding in Peru. They use barley in the mountainous regions for food, so actually mutation breeding was capable to breed the right variety that could grow in high altitudes. From Vienna, Austria, this is Alejandra Silva reporting for the IAEA.
