Application of biotechnology in the selection and breeding of Ngoc Linh ginseng

The research group of Prof. Dr. Duong Tan Nhut, the Central Highlands Scientific Research Institute, has nearly 30 years of experience in research in the field of selecting and breeding Ngoc Linh ginseng (Panax vietnamensis Ha et Grushv.). Recently, the research team has published in 02 prestigious ISI journals (Q1) related to creating transgenic Ngoc Linh ginseng and creating tetraploid Ngoc Linh ginseng. The results from these studies represent an important scientific step forward in improving the Ngoc Linh ginseng variety in Vietnam. These are the first studies in the world on breeding Ngoc Linh ginseng.

Ngoc Linh ginseng is considered a "national treasure" ginseng of Vietnam with more than 100 types of saponin compounds having been identified. Most varieties of Ngoc Linh ginseng planted today are original varieties with diploid chromosomes (2n = 2x = 24). Polyploid cultivars are known to contain a "multiple" increase in genetic material from the original diploid variety, so polyploid plants are generally more productive than diploid plants. In the study published in the journal Scientia Horticulturae (Q1, the prestigious ISI, the research team of Prof. Duong Tan Nhut succeeded in creating tetraploid Ngoc Linh ginseng (2n = 4x = 48) through polyploid treatment with the mitotic inhibitor colchicine.

In addition, the research team also successfully created Ngoc Linh ginseng from the roots of transgenic Ri T-DNA including rolA, rolB, rolC and aux1 through in vitro clonal embryogenesis and nano-iron supplementation in the cultivation environment to increase the quality of Ngoc Linh ginseng seedlings before being planted and domesticated in the nursery. With the above content, the authors have published 01 scientific paper in the journal Plant Cell, Tissue and Organ Culture (Prestigious Q1, ISI .

These are the pioneering research projects in the world in the application of biotechnology and nanotechnology techniques in the selection and breeding of Ngoc Linh ginseng and are also some of the results of the excellent research team that receives financial support for project implementation from the Vietnam Academy of Science and Technology.
