SCREENING QUINCE CULTIVARS AND HYBRIDS FOR RESISTANCE TO FIRE BLIGHT (ERWINIA AMYLOVORA)
This study was conducted to identify quince cultivars that combine fruit quality characteristics and resistance to fire blight. A number of selected quince genotypes from the Pomology Institute (PI) of Naoussa in Greece were evaluated. Considerable variation in fire blight resistance was observed. The following selected genotypes of The Pomology Institute PI 26, PI 37, PI 41 and PI 49 were highly resistant to fire blight and PI 7, PI 22, PI 47 and PI 50 also exhibited notable disease resistance. In addition, the production efficiency and the fruit quality of the above genotypes were higher than the other genotypes evaluated. This study shows that there are several quince genotypes that may be used for fruit production or as pear rootstocks in areas where fire blight is present.
