Orobanche cumana is a kind of malignant weed parasitic in the root of sunflower, which has a great impact on the growth of sunflower. It is of great significance for sunflower industry to carry out Orobanche cumana resistance identification and sunflower resistant breeding. In this experiment, 42 sunflower resources were identified by outdoor pot culture, using highly pathogenic F-race Orobanche cumana. Two immune resources, two highly resistant resources, three resistant resources, 18 susceptible resources and 17 highly susceptible resources were identified. As a whole, oil sunflower materials imported from abroad had better resistance to Orobanche Cumana, while confectionery sunflower materials, including inbred lines and sunflower varieties, had lower resistance to Orobanche cumana. Most confectionery materials were susceptible and highly susceptible to Orobanche cumana except for ZJ105 and GSK18. The resistant materials screened by this experiment laid a foundation for future Orobanche cumana resistant breeding.
