Abstract:
Anthracnose disease of chilli (Capsicum annuum L.) caused by Colletotrichum spp. has been a serious constraint to chilli production worldwide. Two species Colletotrichum truncatum and Colletotrichum gloeosporioides are known to cause anthracnose of chilli in India of which the former is the most predominant one. In the present study, 22 chilli genotypes were screened for anthracnose resistance under both in vitro and field conditions against the pathogen. The study indicated that disease development started at 3 days after inoculation (DAI) on 10^th DAI the observations were taken for calculating percent disease index. Anthracnose symptoms were visible in both matured green and red ripened fruits and the disease resistance was assessed by using 0-5 disease index scale. All the genotypes reacted differently and significantly to the pathogen. Screening results revealed that none of the genotypes were completely resistant to anthracnose. Hence, the new resistant lines need to be developed by breeding programmes for anthracnose resistance in chilli.
