Abstract
The world-wide diversity of ash trees includes genetic information encoding resistance to the ash dieback fungus and the emerald ash borer beetle, which are currently devastating ash populations in Europe and North America. In order to mobilise this genetic diversity in conventional breeding programmes, we need to be able to accurately identify ash species from around the world and cross them with one another. Here, we present a preliminary genetic barcoding system for ash, and a series of hybridisation experiments between European ash and other species. Two of the hybrids show early promise against ash dieback.
