Project Title: Resources for the development of ash trees resistant to ask dieback
Summary: To provide resources (germplasm, genetic knowledge, and propagation methods) to accelerate the selection and production of ash trees resistant to Chalara fraxinea, a novel pathogen which threatens to devastate up to 90% of Europe's ash population.
- Sample genetic variability of Irish populations of common ash (Fraxinus excelsior) and compare to the variability of UK and other European populations;
- Apply genetic knowledge and infection data (gathered from European trials) to predict variation among Irish F. excelsior genotypes in susceptibility to ash dieback (Chalara fraxinea);
- Develop protocols for for the rapid vegetative propagation and recombination of selected resistant/low susceptibility Irish F. excelsior genotypes;
- Conduct an inventory of Ireland's foreign ash species resource (ITS markers will be applied to confirm species identity) with a focus on ash species resistant/tolerant to ash dieback;
- Develop techniques for inter species hybridisation of Irish F. excelsior genotypes with resistant/tolerant foreign ash species.
