Genetic diversity of podocarpus by SCoT markers
摘要
Abstract
The genetic diversity of 8 podocarpus germplasms was analyzed by SCoT markers. The results showed that a total of 136 bands were produced by 10 primers,of which 122 bands(88. 97%)were polymorphic,and the genetic similarity coefficients were between 0. 39 - 0. 80. So there were comparatively great genetic diversity among the podocarpus germplasms. A cluster analysis conducted with UPGMA also showed that the 8 podocarpus germplasms could be classified into 2 groups. The result of principal component analysis (PCA )was the same as the results of UPGMA cluster analysis. SCoT markers can be effectively used to evaluate the genetic diversity of podocarpus germplasms, thus providing a theoretical foundation for the identification and classification of podocarpus germplasms.关键词
