摘要：

Chilli fruits with symptoms of anthracnose were collected from Batangas, Philippines, to determine the etiology of the disease. The fungus was initially identified as Colletotrichum acutatum sensu Into based on its morphocultural characteristics and molecular identity by using primer sets CaInt2/ITS4. Further analyses of three important gene regions, namely internal transcribed spacer (ITS), partial beta-tubulin (BTUS), and glyceraldehyde 3 phosphate dehydrogenase (GAPDH), used in discerning species within the C. acutanun species complex, revealed that the gene sequence of Philippine isolate 0013 had high similarity to known authentic gene sequence of C. scovillei. The fungus induced the anthracnose symptoms on chilli cv. Django fruits in both wounded and un-wounded conditions. This is the first record of C. scovillei as chilli anthracnose pathogen in the Philippines and of the chilli cultivar "Django" as highly susceptible host of C. scovillei 0013.
