Based on culture isolation and morphological observation blight-infected pepper plants in Shaanxi Province, China, we identified the pathogen causing pepper phytophthora blight as Phytophthora capsici. Varieties that differed in resistance (CM334, PBC602, and B27) were inoculated with this pathogen. The root activity of resistant CM334 variety was the highest while that of susceptible B27 variety was the lowest.
Root-knot nematodes of the genus Meloidogyne are important pathogens affecting vegetable crop production in Brazil and worldwide. The pepper species Capsicum annuum includes both hot and sweet peppers; very little emphasis has been placed on breeding sweet peppers for nematode resistance. We report on the inheritance of resistance to Meloidogyne incognita (Kofoid & White) Chitwood race 2 in the hot pepper cultivar Carolina Cayenne. The hot pepper cv. Carolina Cayenne was used as seed parent and the sweet pepper cv.
