The results of an extensive study of 170 morphological, physiological, biochemical, serological and pathological characters of 18 representative isolates from the filbert canker pathogen are presented. These indicate that the bacterium responsible for the disease of filberts ( Corylus avellana ) in Greece is properly characterized as a typical member of the species Pseudomonas syringae. It is placed in group Ia according to the LOPAT tests. The differences in some characters between Pseudomonas syringae pv. syringae and the filbert Pseudomonas , as well as its host specificity, justify its classification as a new pathovar of Pseudomonas syringae and the name of Pseudomonas syringae pv. avellanae pv.nov. is proposed for the bacterium causing the disease ‘bacterial canker’ of Corylus avellana.
