Abstract : Seed health testing of 384 accessions of chilli (Capsicum annuum L.) representing eight states of India revealed the prevelance of Colletotrichum capsici (Syd.) Butler & Bisby in three states, namely Andhra Pradesh, Meghalaya and Uttarakhand which is the causal agent of anthracnose (= fruit-rot and die-back). Out of four Colletotrichum species reported on chilli from different parts of the world, only C. capsici was observed in accessions tested. Occurrence of C. capsici was recorded maximum from Uttarakhand (7.4%). The observations also revealed the occurrence of the pathogen in seed samples up to 5.0 per cent infection index indicating its wide spread in India. Further, correlation analysis revealed that there is highly significant negative correlation between level of infection and reduction in seed germination with r value 0.90 and R2 value of 0.76. The present study confirms the anthracnose of chilli in India is mainly due to C. capsici and the infected seeds are mainly responsible for the long distance spread of the pathogen in absence of effective domestic quarantine.
