对国家种质杭州茶树圃保存的来源于广西的98份茶树资源主要生化成分进行了评价鉴定和遗传多样性分析。结果发现,广西地方茶树资源的生化成分存在丰富的多样性和变异,平均遗传多样性指数达到1.90,平均变异系数达到25.8%。通过多变量的主成分分析,前7个主成分代表了茶树生化成分多样性的86.75%的信息。基于生化成分,把98份资源聚类划分为3个类群。第1类群大部分为红绿茶兼制的资源,第2类群大部分为适制红茶的资源,第3类群大部分为适制绿茶的资源。并从中筛选出一批生化成分特异的资源。
The main biochemical components of 98 tea plant resources in Guangxi province, which were preserved in the national germplasm Hangzhou tea tree nursery, were evaluated and the genetic diversity analyzed. The results showed that there were abundant diversity and variation in the biochemical composition of tea resources in Guangxi. The average genetic diversity index reached 1.90 and the average coefficient of variation reached 25.8%. By multivariate principal component analysis, the first seven principal components represent 86.75% of the information on the biochemical composition of tea plants. Based on the biochemical composition, 98 resource clusters were divided into three groups. Most of the first group is red and green tea-based resources, most of the second group is suitable for black tea resources, most of the third group is suitable for green tea resources. And select a group of biochemical components specific resources.
