Abstract: Anthracnose caused by Colletotrichum gloeosporioides (Penz.) Penz. and Sacc. is one of the most damaging disease causing huge losses in pre and post harvest conditions. Studies were conducted to find out morphological characteristics and sporulation under 16/8 hours light and darkness condition in vitro on PDA. Isolates were obtained from Mangifera indica, Citrus aurantifolia, Catharanthus roseus, Psydium guavajava, Punica granatum, Carica papaya, and Glycine max. Pathogenicity of these isolates was proved on their native hosts. It was revealed that there was variation in growth. Maximum radial mycelial growth was attained by Cg6 isolate (89mm) at 8th DAI and minimum radial mycelial growth was in Cg2 isolate. Maximum conidial length was observed in Cg1 isolate (12.57-19.62µm) while maximum breadth was observed in Cg6 isolate (3.0-7.5µm). It was clearly observed in all the isolates that there were no visible setae. Variation in colony colour was observed and acervuli were brownish to blackish in colour with raised conidial mass. Sporulation study revealed that Cg6, Cg5 and Cg3 isolates showed good sporulation while Cg1, Cg2, Cg4 and Cg7 isolates showed poor to medium sporulation under 16/8 h condition of light regime.
