Abstract
Colletotrichum is one of the most important plant pathogenic genera affecting different plant species, particularly tropical and sub-tropical crops and fruits.Species of the genus can cause many diseases, including fruit rots, crown rots, stem end rots, and anthracnose.The objective of the present study was to identify the Colletotrichum species associated with durian fruit rots in northern Thailand.Based on morphological study and phylogenetic analyses of five loci (internal transcribed spacer (ITS), actin (ACT), chitin synthase 1 (CHS-1), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and ß-tubulin (TUB2)), four species belonging to three complexes were identified and described.Colletotrichum durionigenum is introduced as a new species, and C. gigasporum, C. pandanicola, and C. truncatum are described and illustrated as new host records.
