Abstract

The extent of genetic variation in a Clonal Seed Orchard (CSO) revealed low genetic variation, and the UPGMA dendrogram constructed with genetic similarity data did not yield a firm pattern with respect to the geographic location of the mother tree. In the CSO, all the flowered clones were not able to produce seeds. Seed germination showed that only two clones were able to germinate. Mantel test showed that genetic distance was positively correlated to height and Gbh and negatively related to flowering of clones in the orchard.
