摘　　要：在茶角胸叶甲暴发流行于茶树资源圃的次月,通过测定当年生茶枝第3叶虫孔数目与为害面积,鉴定评价了57份茶树种质材料对茶角胸叶甲(Basilepta melanopus Lefevre)的抗虫性和抗性等级。研究表明,所鉴定材料中未发现完全免疫的茶树资源,但明确61-丰-01、宋坳73-01、中叶黄、白毫早、槠叶齐抗虫性强,同时发现福大60、雨大3号、苦茶47与苦茶3号均为中高感茶树品种(系)。57份茶树种质资源之间抗茶角胸叶甲能力存在较大差异,中小叶种和苦茶资源抗虫性较差,在抗虫性品种选育时可进行规避。This study aimed to identify and evaluate the resistance of 57 tea tree germplasm materials to Basilepta melanopus Lefevre and to provide a theoretical reference for the selection of insect-resistant tea cultivars.The resistance of tea tree resources from a wide range of sources was evaluated by measuring the spot and area of B.melanopus damage on tea leaves in the month following the outbreak of B.melanopus population.The study showed that none of the tested materials was immune to this insect pest.However,it was evident that 61-Feng-01,Song′ao 73-01,Zhongyehuang,Baihaozao,and Zhuyeqi were highly resistant to B.melanopus,while Fuda 60,Yuda 3,Kucha 47,and Kucha 3 were medium to highly susceptible tea tree cultivars(lines).Among 57 tea tree germplasm resources,significant differences in resistance to B.melanopus were observed.It is recommended to avoid using germplasm materials with low resistance,such as medium and small leaf species and bitter tea resources.
