Tóm tắt

The tea plant Camellia sinensis is an economically important species worldwide, especially in Asia. C. sinensis var. assamica is one of the four varieties of C. sinensis, and the tea from C. sinensis var. assamica has a high economic value. Several phylogenetic studies on Camellia were conducted, however, the phylogenetic studies to investigate the relationship of C. sinensis var. assamica from Vietnam are limited. Identifying the phylogenetic position and genetic relationship of C. sinensis var. assamica from Vietnam is significant in providing essential information for taxonomic study and economic resources. The present study, based on the molecular data of four DNA regions supported the monophyly of C. sinensis. The Camellia sinensis var. assamica from Vietnam formed a clade together, but it is far from Camellia sinensis var. assamica from India and China. The results support the evolution in the genetics of C. sinensis var. assamica between regions, however, the current genetic variations do not influence classification yet. C. sinensis has been grown in several regions in Asia, however, the conservation of native populations of Camellia sinensis var. assamica is necessary and should be carried out for sustainable development.
