摘　　要：[目的]评价110个普通油茶无性系对炭疽病的抗病性,为油茶炭疽病抗性种质材料筛选和优良品种推广提供科学依据。[方法]采用田间调查方法和病情指数法,调查2014、2016年两年中110个普通油茶无性系的抗病性。[结果]在参试的110个普通油茶无性系中,未发现免疫(I)、高抗(HR)、高感(HS)无性系,抗病无性系10个,中抗无性系30个,中感无性系65个,感病无性系5个,其中9号、21号、27号、40号、45号、66号、150号、164号、177号、219号是10份抗病无性系。[结论]综合两年调查结果筛选出9号等10份抗病无性系,为深入研究普通油茶抗炭疽病机制和抗病育种提供了育种基础材料和参考依据。[ Objective] To evaluate the resistance of 110 Camellia olejfera clones to anthracnose in order to screen and extend elite resistant varieties. [ Methodl Based on anthracnose investigation in 2014 and 2016, the disease index was used to evaluate the resistance of 110 clones. [ Resultl No clone under assessment was found with im- mune, highly susceptible or highly resistant to anthracnose. 10 clones were resistant, 30 clones were moderately re- sistant, 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 fur- ther studying the resistance mechanism on C. oleifera.
