| Abstract: | Objective] To evaluate the resistance of 110 Camellia oleifera clones to anthracnose in order to screen and extend elite resistant varieties.Method] Based on anthracnose investigation in 2014 and 2016, the disease index was used to evaluate the resistance of 110 clones.Result] No clone under assessment was found with immune, highly susceptible or highly resistant to anthracnose. 10 clones were resistant, 30 clones were moderately resistant, 65 clones were moderately susceptible, 5 clones were susceptible.Conclusion] Based on the results of two years'' survey, 10 resistant clones are selected, which can be used as references and breeding materials for further studying the resistance mechanism on C. oleifera. |
