| 摘 要： | 按照茶树的原产地(生态区)、树型和品种类型将我国茶树种质资源分为18组,各组通过离差平方和法聚类,采用系统取样和随机取样相结合,并依遗传多样性指数加以调整.从615份茶树种质资源中选取126份种质作为核心样品,经过遗传多样性t测验、农艺性状检验.结果表明,初选出的核心样品具有良好的代表性.

| Abstract: | Camellia sinensis germplasm in China were divided into 18 groups according to their origins, tree forms and variety types. In each group, numbers of entries were decided based on using sampling strategies combined stratification with random and cluster analysis by Ward's methods. A pre-core germplasm comprising 126 accessions from 615 Chinese tea plants was constructed.After the t-test of Shannon diversity index and the evaluation of agro-ecological characteristics, the pre-core germplasm could represent the genetic diversities of the whole collection. |
