Abstract
This project aimed to develop a better understanding of the potential risks of gene flow and to generate isolation distances required for genetically modified (GM) OSR. The study examined biotic (insect) and abiotic (wind) pollen dispersal over two seasons. A considerable portion of work was devoted to the development of molecular markers, to differentiate Brassica napus varieties from each other to distinguish them from their wild relatives. The project broadly aimed to study gene flow, via pollen movement, from OSR but specifically aimed to: ! Characterise B. napus cv. Marinka using molecular markers. ! Elucidate the distance travelled by OSR pollen by biotic dispersal. ! Elucidate the distance travelled by OSR pollen by abiotic dispersal. ! Elucidate pollination/seed set at various distances from a source crop using male sterile bait plants. ! Develop risk assessment/containment strategies.
