Abstract
Biogeographical assay provides knowledge on differences in natural gene flow in different regions, which is essential information for an ecological risk assessment for field releases of transgenic crops. In a given region, a biogeographical assay is performed to know whether wild relatives are present in the area or not, following the principle “species by species, region by region” [1, 2]. Data sources are combined to detect natural hybrids between crops and related wild species. As a synthesis, risk categories for natural gene flow are defined for the test region [1; see K. Ammann, this volume]. To obtain basic data for an ecological risk assessment and a long-term monitoring accompanying field releases and large-scale cultivation of GMP’s, biogeographical distribution and hybridisation potential of crops and related wild species have to be studied on non-transgenic plants, ideally before first field releases have been persecuted.
