The disease caused by P. capsici can attack all tissue and growth phases of the chili plant with the yield loss up to 100%. The research aimed to evaluate the resistance response of thirty Indonesian chili varieties against P.capsici that have been carried out at the IVEGRI research station - Lembang, West Java since April until July 2020. The selection method was carried out using the artificial inoculation. A total of 10 ml of zoospores with a density of 10 6 were inoculated on chili seedlings five weeks after sowing. The observations were carried out by scoring symptoms that appeared (score 0 to 5) five times. The observation was carried out at 7 to 35 days after inoculation with intervals of 7 days. Based on disease severity (DS), the resistances of varieties were grouped into three levels, namely resistant (DS 50%). The result showed variations on symptoms, scoring, and the time of symptom appearance in and between the varieties tested. The evaluation result showed that 24 varieties were resistant, 5 moderately resistant, and 1 susceptible to P. capsici .
