Abstract

Pepper seedlings in 4- or 5-leaf stage were inoculated by spraying the mixture of spore suspension (approximate 1X10 6 spores/ml) of both Colletotrichum coccodes and C. capsici. They were then kept wet and incubated in greenhouse under 27-28C. Every plant was respectively examined and recorded for symptoms on leaves and stem on the 7th and 14th day after inoculation. Various varieties of pepper were finally compared in their disease indexes. 1,015 varieties of pepper were evaluated for their resistance to anthracnose. The results showed that 91 varieties (8.96%) were resistant, 174 (17.14%) tolerant, 582 (57.33%) susceptible and 168 (16.55%) highly susceptible. Some resistant varieties showed relative resistance to TMV and CMV as well.
