Abstract
The most dominant disease attacked hot pepper plantations is anthracnose (Colletotrichum acutatum). This disease can attack fruit, causing substantial losses in quality and quantity of 20% - 90%. The purpose of this research is to select lines or varieties of hot pepper that are potentially resistant to Colletotricum acutatum. This research was carried out at the Indonesia Vegetable Research Institute from January to December 2018. Samples of anthracnose-infected plants were taken from several locations in West Java. Identification of C. acutatum isolates was done by PCR method. The results showed that: (1). The intensity of anthracnose disease is different in five districts (Bandung, Garut, Tasikmalaya, Ciamis and Sukabumi) ranging 50% - 73%. The high intensity of anthracnose symptoms depends on cropping patterns, used of varieties, age and plant conditions. (2). The morphology of the isolate the top view white and gray, and beige, white, peach for the colony the bottom. (3). C. acutatum isolates from West Java were identified by PCR, DNA band measuring 490 bp. (4). The isolates from Sukabumi were the most virulent. (5). Inoculation of 5 isolates from West Java on hot pepper were not obtained resistant lines / varieties.
