Abstract: a method about the identification of sunflower verticillium wilt resistance: a quantitative method for dipping bacteria solution was studied in this paper.This method is close to actual sunflower growth conditions, can be carried out at any time to identify the sunflower verticiflium wilt resistance through the method. Resistant (S18) and susceptible (P77) sunflower genotypes infected with V dahlia by this method. The results of pathogenic detection showed that resistance characteristics of resistance genotypes S l 8 was significantly higher than that of susceptible genotypes P77; physiological and biochemical index determination results showed that the change of soluble protein content and POD activity of two genotypes are different. Generally, the content of soluble protein was higher in resistance genotypes S18 than in susceptible genotypes P77. After infected with V dahlia, the POD had a stronger activity in resistance genotypes S 18 when compared with susceptible genotypes P77.
