Abstract

The research conducted to observe the diversity of Colletotrichum sp. associated with anthracnose on chili. The diversity was observed from morphology of conidia. Colletotrichum sp. was isolated from Capsicum frustescens, C. annum (big chili variety and red curly chili) with anthracnose symptoms. In the isolation process, two isolates were obtained from C. annum big chili variety (BA and BB), 5 isolates were isolated from C. annum red curly chili (DPTK1, DPTK2, KA, KC, and KD), and 7 isolates from C. frustescens (DPTR1, DPTR2, RA, RB, RC, RD, and UPN4). Conidia length, shape, and color were observed. Isolate BA from C. annum big chili variety has the longest conidia than other isolate in average (16.10). Isolate RA from C. frustescens has the shortest conidia than other isolates (10.05). All isolates have hyaline color. Isolate BA, DPT K-1, RC, RD, and UPN4 have Fusiform shape. Isolate with cylindrical with rounded apices is BB, DPT K-2, KA, KD, DPT R-1, DPT R-2, RA, and RB. Conidia of Colletotrichum sp. isolated from Capsicum frustescens and C. annum have hyaline colour and diversity on the length and shape.
