| Abstract: | Symptoms of bitter rot were observed on apple and pear fruits in the field and in storage in Croatia between 2009 and 2011. Fifteen Colletotrichum isolates from apple and two from pear were collected and identified by sequencing of the ITS1 and ITS2 regions of the ribosomal DNA. Phylogenetic analysis revealed that ten isolates from apple and two isolates from pear could be identified as Colletotrichum fioriniae, five isolates from apple were clustered in Colletotrichum clavatum, while one isolate was in the Colletotrichum acutatum A7 group. All isolates caused typical bitter rot symptoms when inoculated on apple and pear fruits. |
