200 varieties of artificial plants

With 50 laboratories of the state and the private sector and the leading Asian seedling factories (Japan, Taiwan), Da Lat is the leading country in seed production with tissue culture technology. These seedlings are also exported to Japan, Korea, Taiwan, the Netherlands .

Not only scientists, but also farmers in the flower city of Da Lat are now familiar with the scientific concepts of tissue culture, clonal cloning to create precious varieties.

In the North, vegetative cloning has been applied in most agricultural and forest products, successfully preserving genetic resources of precious woods such as incense (woods extracted from essential oils used in pharmaceuticals, cosmetics), Logs for timber, yellow tea - tea is difficult to grow. This technique also helps to successfully create drought tolerant rice variety DR1, multiplying many types of potatoes and sugarcane.

With the capital of dozens of cloned and preserved plant varieties, the Institute of Biotechnology (Vietnam Science and Technology Center) is continuing to study the extraction of secondary active ingredients to produce diarrhea medicine. Berberin from Celandine - Medicinal herbs only grow in Hoang Lien Son Mountains .

These are the new breeding applications using gene technology by tissue culture of the Institute of Biotechnology - one of the leading units of cloning research in Vietnam.

At the end of last October, the Agricultural Genetics Institute also announced successful industrial and semi-industrial breeding for a number of high economic value flower and forest trees; select 18 lyly flower varieties, 10 varieties of pink monkeys with diverse colors and designs of high economic value and over 15,000 saucy, teak, frankincense seedlings .

The process of rapid multiplication of aromatherapy and medicinal plants, teak trees (a high-value shipbuilding material) and purple marijuana (a rare species) have been completed by researchers. export.

Mr. Do Nang Vinh - Deputy Director of the Institute of Agricultural Genetics - said: "Creating asexual embryos, artificial seeds is an advanced technology in the world, first studied in our country. This discovery has been much seed companies receive to disseminate in high-tech agricultural production system ".

Asexual embryos can be stored for a long time and germinated at the right time. According to Vietnamese scientists, up to now, more than 200 species of plants have been propagated by cloning technology. Cloning can create artificial seeds, this is a favorable factor for mechanization and automation of industrial breeding. For example, with coffee, from 1 gram of biomass, in a few months it is possible to create 60,000 clones with a regeneration rate of 47%.
