【摘要】 利用RAPD标记对四川主要产茶区具代表性的36份茶树栽培品种的亲缘关系进行分析。从50条引物中筛选出扩增效果良好的16条,共扩增出167条谱带,其中,多态性带为158条(占94.61%),遗传距离的变异范围在0.149~0.679之间。UPGMA聚类结果将36份茶树栽培品种分为3个复合组和2个独立组,聚类结果与茶树品种的来源有关。更多还原

【Abstract】 The genetic relationship of 36 tea cultivars grown in Sichuan was studied by RAPD technique.Sixteen primers selected from 50 random primers were used to amplify 36 tea samples,and a total of 167 DNA bands were amplified,among which 158(94.61%)were polymorphic.Genetic distances between the cultivars varied from 0.149 to 0.679.UPGMA cluster analysis of 167 bands amplified by 16 primers was made.The result showed that 36 tea cultivars tested could be classified into 3 complex groups and 2 simple groups.It was found that there was a certain correlation between the results and the derivation of tea cultivars.更多还原
