Fire blight, caused by Erwinia amylovora (Burr.) Winslow et al. is twenty years old and the most destructive disease of pears and to a lesser degree of apples, quinces and several other members of the Rosaceae family in the Republic of Macedonia. E. amylovora is a quarantine pathogen for the country and has already caused considerable material damage in orchards with a tendency for further spreading.
E. amylovora was reported in the Republic of Macedonia for the first time in 1991 on pear (Pyrus communis) and quince (Cydonia oblonga). During the 1991-1993 periods, a detailed investigation of all the regions in Macedonia where pear, apple and quince were cultivated was conducted. Since then, the pathogen has been consequently detected in different regions in Macedonia, and a lot of pear and quince trees have been destroyed because of the presence of these bacteria.
Fireblight, until now, has never been detected on the wild pear in Macedonia. Some opinions are that P. pyraster is a resistant variety and it can be used for genetic crossing in order to obtain a resistant variety of pear. Research papers on collecting germplasm on Pyrus species published in journals in Yugoslavia, including the collection of P.pyraster in Macedonia, demonstra-ted that it is possible to produce seedlings with high degrees of resistance to the diseases and insects pests.
This study was the first characterization and identification of E. amylovora strains isolate from wild pear, apple, pear and quince by using classical methods for identification, BIOLOG tests and modern molecular method (PCR).
