Abstract

Morphological characters of ten mouoconidial isolates of Colletotrichum capsici. anthracriose pathogen of chilli was investigated. Among the ten isolates of C capsici, Cc8, Cc10, had white to ash dark black grayish yellow colonies with saffron colour conidial mass. Appressoria possessing varied type of shape and size developed after three days of incubation in all isolates of C. capsici except Cc6. The maximum radial mycelial growth was observed in Cc10; (78.03 mm) followed by Cc2 (76.73 mm). Micrometrical observations also revealed large variation in dimension of conidia, acervuli and setae.
