Resistance screening were conducted on 28-days-old pepper plants grown in 72-cell fl  ats by inoculating 5 mL of inoculum (contain 105 zoospore mL-1) to the base of each plant. Phytophthora capsici isolate used in this experiment was TG01, which then identifi  ed as race-3. The evaluation of pepper genotypes characteristics were conducted in fi  eld.  Eight characters demonstrated a wide genetic variability; those characters were resistance to Phytophthora blight, infection period, dicotomous height, canopy width, fruit weight, fruit length, fruit diameter and production. These characters along with fruit wall thickness, chlorophyll-a, chlorophyll-b, total chlorophyll had high heritability values. Using path analysis infection period, dicotomous height and fruit diameter are recommended to be simultaneously used as selection criteria for developing Phytophthora blight resistant pepper varieties. Keywords : capsicum, Phytophthora capsici, selection criteria, path analysis
