摘要: 用易感茶芽枯病的6个品种和3个抗病品种进行间栽和净栽试验,并对10个品种种质的遗传多态性、亲缘关系进行RAPD分析。结果表明:10个茶树品种聚类结果分为2个复合组和3个独立组,多态性谱带为110条(占89.43%),间栽比净栽茶芽枯病叶片受害面积,受害面积百分率,发病率及病情指数间栽后均有显著下降。易感品种下降幅度更大,防治效果达28.5%~73.77%,利用品种的多样性混合间栽是控制茶芽枯病的有效途径。

Abstract: Field experiments of mixed and single-cultivar-planting of 6 susceptible cultivars and 3 tea bud blight-resistant cultivars, and the genetic diversity, and the relationship of 10 tea cultivars were investigated by RAPD. The results demonstrated that 10 tested tea cultivars can be classified into 2 complex groups and 3 simple groups, a total of 110 polymorphic DNA bands were amplified (89.43%). The disease incidence infected leaf-area percentage disease index and infected leaf area in the mixed planting plots were significantly lower than those in the single-cultivar-planting plots. The susceptible cultivars showed significant greater decreasing range the control efficiency gained 28.54%~73.77%. It suggests that inter-planting of tea cultivars with different genetic background and morphological characteristic is an effective approach for tea bud blight control.
