Abstract

Anthracnose is one of the most destructive pepper diseases in Indonesia. Colletotrichum acutatum has been identified as a predominant species in pepper fields of Asian countries including Indonesia. The experiment used completely randomized block design with 2 factors and 4 replications. The first factor was 14 genotypes (c-1,2,3,4,5,7,8,9,15,18,19,28,47, and 49, and the second factor was 4 isolates of C. acutatum (PYK 04, BGR 027, MJK 01, and PSG 01). Each experimental unit used 10 green pepper fruits.  Inoculation methods followed the AVRDC procedure and resistance score followed the modified procedure of Yoon method. Symptoms were evaluated five days after inoculation. Disease incidence was evaluated using Yoon method with slight modifications. The experiments showed that C-15 genotype was more resistant to anthracnose than others; C-8 and C-49 genotypes were recorded as susceptible to anthracnose. Except the three genotypes, all other genotypes were recorded as highly susceptible to anthracnose. Capsaicin content and peroxsidase activities were not correlated with resistance to anthracnose.   Key words:  pepper, resistance, anthracnose, Colletotrichum acutatum
