An application was submitted by Monsanto Company to request the authorisation of genetically modified stack (GM stack) MON 87708 ? MON 89788 soybean (tolerant to dicamba and to glyphosate) and all sub-combinations of the individual events as present in the segregating progeny, for food and feed uses, and import and processing, in accordance with articles 5 and 17 of Regulation (EC) N? 1829/2003 GM Food and GM Feed. The unique identifier assigned to GM stack MON 87708 ? MON 89788 soybean is MON-877?8-9 x MON-89788-1. The GM stack MON 87708 ? MON 89788 soybean has been obtained by conventional crossing between two genetically modified soybean events: MON 87708 and MON 89788, without any new genetic modification. The EU-RL GMFF has previously validated individually, and declared fit for purpose, the detection methods for the single events MON 87708 and MON 89788 (see http://gmo-crl.jrc.ec.europa.eu/StatusOfDossiers.aspx). In line with the approach defined by the ENGL (http://gmo-crl.jrc.ec.europa.eu/doc/Min_Perf_Requirements_Analytical_methods.pdf) the EU-RL GMFF has carried out only an in-house verification of the performance of each validated method when applied to genomic DNA extracted from GM stack MON 87708 ? MON 89788 soybean. The results of the in-house verification led to the conclusion that the individual methods meet the ENGL performance criteria also when applied to genomic DNA extracted from the GM stack MON 87708 ? MON 89788 soybean.
