Abstract

Podocarpus is a genus of conifers which is belonging to Podocarpaceae family. Podocarpus comprises of over 100 species and widely spreading in many areas of the world. Podocarpus plants are available in nature and distributed in subtropical and tropical forest areas in Vietnam. This plant is grown as an ornamental tree with potential economic benefits in whole of this country. The objective of this study was to evaluate genetic diversity and identification of 12 local Podocarpus samples collected in the mountainous areas of Yen Tu, Quang Ninh province by ITS markers. The results showed that the samples were genetically diverse with high genetic similarity, of which the greatest homogenetic was 98.74%, while the lowest was 87.52%, respectively. Noteworthily, the nearest genetic distance was 0.01, whereas, the farthest was 0.14. It implies that some samples of Podocarpus may have an identical origin, evolution and relationships. We have also successfully identified 12 Podocarpus samples belonging the Podocarpus macropyllus based on the published reference on Genbank (NCBI). This study may provide useful information to further conservation efforts and development as well as exploitation of the genetic resource Podocarpus in this country.
