Abstract
We evaluated 209 Capsicum accessions from the National Agrobiodiversity of RDA, for their reaction against of anthracnose disease caused by Colletotrichum acutatum. Two hundred nine accessions of Capsicum were almost composed with Capsicum annuum var. annuum originated from 37 countries. The percentage of infection due to C. acutatum ranged from 11.1% to 100% on immature and matured pepper fruits at 21 days after inoculation. On immature fruits of pepper, one hundred seventy three accessions of tested pepper were found infected with C. acutatum. Out of the 173 accessions, eighty five accessions were susceptible to anthracnose with dark brown to black lesions and slowly increased in size at 21 days after inoculation. Only thirty six accessions showed resistance against C. acutatum. On mature fruits of pepper, one hundred ninety eight accessions were infected with C. acutatum at 21 days after inoculation. Twenty one accessions showed a resistance reaction against C. acutatum. The results of this work indicated that all of resistance accessions to C. acutatum were have a genetic potential for the resources of resistance can be further used in pepper breeding programme against anthracnose and also demand more detailed investigation in this.
Key Words: anthracnose, capsicum, Colletotrichum acutatum, resistance
