抗茶炭疽病茶树核心种质资源的筛选

Screening of a Core Germplasm Resource Resistent to Tea Anthracnose from Tea Trees

以228个茶树品种(系)为材料,通过室内病菌回接致病试验和田间病害调查,明确各材料抗茶炭疽病的差异,结果分别获得71个和48个在回接病菌发病及田间调查中发病率低的茶树品种(系),筛选发病率均较低的18个茶树品种(系)为抗茶炭疽病的核心种质资源。

The difference of resistence to Tea Anthracnose among 228 tea cultivars were evaluated by inoculation with pathogen and diesease survey in fields. 71 plus 48 cultivars with lower incidence of Tea Anthracnose were obtained respectively by indoor and field investigation. 18 tea cultivars with lower incidence in both experiments were screened as core germplasm resource with resistence to Tea Anthracnose.
