dc.description.abstractThe importance of gene movement from cultivated plants has been highlighted in regard to minimising the movement of seed and/or pollen between GM and non-GM crops (i.e. gene flow). Although ryegrass covers in excess of 90% of Ireland’s agricultural area, very little is known about gene flow from ryegrass populations from an Irish context. The goal of this project was to address this lack of data by measuring the degree of pollen-mediated gene-flow between two Lolium spp. in a field environment. Ryegrass (esp. Lolium perenne) was selected because as the dominant pasture grass it is critical for the livestock industry as well as being a current target for novel improvements. The results from this research indicate that the potential for pollen-mediated gene flow from perennial ryegrass decreases exponentially with increased distance from the pollen source, with hybridisation events recorded out at 192m. In parallel to this research, a separate study was conducted to assess the degree of genetic diversity within feral and wild Lolium spp across Ireland and also within the important crop weed Avena fatua (‘wild oats’); thereby providing an insight into the degree of historic gene flow that has occurred within each species and in regard to the latter, identifying the potential for non-native A. fatua to colonise the Irish agrienvironment.en_GB
