摘要
高效液相色谱检测茶树(Camellia sinensis(L.)O.Kuntze)14个红富贵×红交27的F1代单株、7个红交27×F95181 F1代单株及其亲本中各儿茶素组分含量,利用主成分分析和聚类分析研究了茶多酚在品种间杂交F1代的遗传规律。结果显示,红富贵×红交27 F1代14个单株茶多酚的表型以3:10的分离比例被分成类似于母本的表型集群和类似于父本的表型集群;红交27×F95181 F1代7个单株茶多酚的表型以2:5的分离比例被分成类似于母本的表型和类似于父本的表型集群。由此推测,与母本相比,父本在茶多酚的遗传上具有偏向于显性的遗传倾向。主成分分析和聚类分析可最大限度地获得茶多酚表型的遗传信息,对开展以茶多酚为主的成分育种具有理论和现实意义。
Hereditary patterns of tea ployphenols in F1 hybrids of Camellia sinensis（L.） O.KUNTZE were analyzed by principal component analysis（PCA） and cluster analysis in 14 F1 hybridized individuals of Benifuuki × Benikou27,7 of Benikou27×F95181 and their parents.The results showed that the tea ployphenol phenotypes in 14 F1 individuals of Benifuuki×Benikou27 were divided into the female parent and male parent-like clusters in the ratio of 3：10,although the ratio in 7 F1 individuals of Benikou27×F95181 was 2：5.The results showed that the hereditary patterns of tea ployphenols are likely to be more dominant in male than that female phenotypes.PCA and cluster analysis can be a useful tool for finding the information on hereditary patterns of tea ployphenols,thus it would be helpful for breeding the specific tea plant lines.
