    Keywords : ash dieback; Fraxinus excelsior; Hymenoscyphus fraxineus; disease tolerance; heritability;

    Abstract : European ash (Fraxinus excelsior), a tree species with both economic and ecological importance, has experienced a steady population decline in Europe since the early 1990’s due to ash dieback, caused by the pathogen Hymenoscyphus fraxineus. In 2001, the first observations of ash dieback were made in Sweden and by 2010, ash had become a red-listed species. READ MORE
