The TPERCNVC(technique for plant efficient and rapid clone non in vitro culture) is an initiative set of hi-new technique which can be used in the large scale rapid cloning of many economic plants. Li Chang Xiao, associate professor and president of the NKBI(Ningxia Kelong Bioengineer Institute), manger and president of the NKC(Ningxia Kelong Company Ltd.), and vice chairman of the NBB(Ningxia Biology Board), has spent ten years on this technique
This technique made important breakthroughs both to the plant tissue culture technique and to the conventional seedling techniques.
In 1993, it passed the provincial experts authentication. In Oct. 1995, it was examined then verified to be at the leading level in the world, by Chinese Agriculture Science Academy(CASA).

The TPERCNVC can be widely used and extensively spread. Success in the rapid cloning of one specie may drive or promote the high speed development of one industry. Since its born, it has been tested in over 350 species of economic plants. The comprehensive rapid cloning coefficient reached or even surpassed that of plant tissue culture. It also showed an universal significance in the cloning of most species.
There are more than 65 million seedlings have been cloned and spread in over 145,000 mu areas. Some species have been largely spread for 16 years, and contributed much to the development of industrialization of agriculture, forestation and horticulture.This technique has showed its great potentials in the economic construction, and therefore been praised as "A great beginning of the green copying".
