The results showed that Bijiexianjiao, Leishanzhaotianjiao, Zunyichaotianjiao were highly resistant. There were 7 resistant varieties, 6 middle - resistant varieties and 5 susceptible varieties. The ratio was 14.3 %, 33.3 %, 28.6 %, 23.8 %, respectively. The results of 7 peppers identified resistance to pepper phytophthora blight in field showed that series of Xiangyan varieties were highly susceptible, and local varieties such as Zunyichaotianjiao, Xiangla-1 and Suiyanglajiao had better resistance, especially dried pepper varieties.
