Abstract

Sooty blotch is a disease of apple and pear caused by a complex of fungi that blemish the fruit surface. Results of molecular studies indicated approximately 30 different fungi species associated with this disease. Apples and pears with symptoms of sooty blotch were collected in summer and early autumn 2006–2010 from trees grown in fungicide non-treated orchards and small gardens located in various regions of Poland. Fungi causing sooty blotch were isolated from fruits and the isolates were divided into six groups, according to their morphological characters. Growth of the fungi colonies were tested on different agar media (PDA, CMA, MEA and Czapek). The ITS region of rDNA from 16 isolates from the first group was amplified by PCR technique and one representative sequence of this isolates was used to alignment in Gene Bank. This isolate was identified as Aureobasidium pullulans and isolates from this group were compared with it on the base of morphological features.
