应用 DNA指纹分析技术对三门“香山早”3个不同茶树品系与本省 5个主要的特早生茶树品种进行遗传鉴定。 19个引物 RAPD分析共扩增出 12 6条谱带 5 89个位点 ,其中多态性占 78%。DNA指纹分析表明 ,“香山早 1号”和“香山早 2号”属于同一遗传类型 ;供试比较的 5个特早生品种与该 3个品系是不同的遗传类型 DNA fingerprinting analysis was used to make genetic identification of three different tea tree varieties in Xiangshan early and five major pre-emergence tea varieties in our province. A total of 1289 bands were amplified by 19 primer RAPD analysis, of which 78% were polymorphic. DNA fingerprinting analysis showed that “Xiangsanzao 1” and “Xiangshanzao 2” belonged to the same genetic type. The five premature varieties tested were different genetic types from the three strains
