The objective of this research was evaluated the resistance of four hot pepper to antracnose on pre harvested and (2) evaluated the best method to needed inoculated of the resistance antracnose and (3) to find the superior genotipe of resistance antracnose. The research was conducted in the Greenhouse of the Department of Agronomy and Laboratory of the Department of Plant Pest and Disease, Faculty of Agriculture, Bogor Agriculture University, until 12 month. Resistance evaluation on pre-harvesting fruits was done in the Greenhouse with 'spray' inoculation method of 1000000 spore/ml Colltotrichum gloeosporioides suspension at flowering state and fruit-set stage. The research were set in a Factorial and Completely Randomized Design with four replication and five plants per experimental unit. The genotipes evaluated were UPM, Tit Super, Yogya, and Jatilaba. Observations were done on disease severity, disease incidence and percentage fruit damage. The results showed that resistance level of all genotypes were lower when inoculated at fruit-set stage compared to at flowering stage. The best method of evaluation for resistance to antracnose on hot pepper wa the Greenhouse test inoculation at fruit-set stage with variable of disease incidence. All genotypes tested were considered very susceptible to Colltotrichum gloeosporioides (antracnose).
