摘要：ABSTRACT: Twelve isolates of Colletotrichum capsici from various places were characterized into three groups based on morphological characters and growth rate. Different isolates (Cc1,Cc4,Cc6, Cc7, Cc8, Cc10 and Cc12) are present in middle virulence (II group), isolates (Cc3,Cc5 and Cc9) are present in low virulence (III group) and isolate Cc2,Cc11 is present in High virulence (I group). The effect of Colletotrichum capsiciwas tested onfive chilli varieties for their disease interactions. The results revealed that these isolates could be differentiated in disease severity. The degree of disease severity as a size of necrotic symptom was different on each tested variety and varied from 0.47 to 2.68.The mean value of 12 isolates is varied from 1.67 to 4.01mm/lesion diameter while mean value of five variety is varied from 0.47 to 2.71 mm/lesion diameter and CD of five variety is 0.0 – 2.21 mm/lesion diameter. These varieties show 7.38 mm critical variance in five varieties.In twelve isolates the lesion diameter is varied from 3.09 to 21.01. KEY WORDS: Chilli, Anthracnose, Colletotrichum Capsici, Disease Severity, CD.
