利用RAPD分子标记技术,对湖南典型茶树安化云台山种(Camellia sinensis var.sinensis)、城步峒茶(C.sinensis var.assamica cv.Duntsa)、汝城白毛茶(C.ptilophylla)和江华苦茶(C.sinensis var.assamica cv.Jianghua)4个地理种群的240个单株的遗传多样性、种群内和种群间的遗传变异进行了研究.结果表明,21个10碱基随机引物共检测到226条谱带,其中多态性谱带为201条,占88.9%.遗传多样性分析结果显示:Shannon's多样性指数为0.43,种群内变异占74.7%,而种群间变异占25.3%;Nei's指数群体总基因多样性(H_T)为0.37,群体内平均基因多样性(H_S)为0.28,群体间的基因多样性(H_(ST))为0.09,群体Nei's基因分化...

Genetic diversity and genetic variation of 240 adult plants of four tea populations, Camellia sinensis var. sinensis, C. sinensis vat. assamica cv. Duntsa, C. ptilophylla and C. sinensis var. assamica cv. Jianghua in Hunan, were studied by using RAPD markers. The results showed that 226 loci were found by using 21 random primers （10 bp）, of which 201 loci were polymorphic （88.9%）. The analyzing result of genetic diversity indicated that Shannon＇s index was 0.43, 74.7% of which was within population genetic diversity while 25.3% was among p...
