Protection of Tropical Crop Germplasm Resources in China

The protection of Chinese tropical crop germplasm resources,which plays an important role in biodiversity and constitutes the material basis of the sustainable development of domestic tropical crops,is essential to the development of tropical crop industry.Since 1978,several research studies and collections have been carried out,and 47 000 copies in the form of germplasm nursery,in vitro library,and seed bank have been saved.The identification and evaluation of tropical crop germplasm focused on quality traits,stress tolerance,pest resistance and cytological traits,etc,which has established a standardized database that can be publicly shared through the tropical crop germplasm resources information network.But there are still problems such as unclear resource detail,unsubstantial foundation of resource research,lack of resource innovation,inadequate storage facilities,lack of storage techniques,faint consciousness of sharing and lack of mechanisms for sharing,etc..It is suggest to carry out a comprehensive survey and collection of domestic resources while introducing and studying foreign resources.The identification and evaluation need to be strengthened.Furthermore,to promote the sharing of resources and cultivate new varieties with independent intellectual properties,creation of germplasm resources needs to be increased and the sharing mechanism has to be established.
