Gene Modification of Pharmic Plant Germplasm Resources

Abstract

Germplasm resources refer to the basic materials for selecting and cultivating new species, which include propagating materials of cultivated species and wild species from different plants and genetic materials of various plants artificially created based on the propagating materials above. Pharmic plant germplasm resources are mainly composed of all of the pharmic genetic resources from pharmic plant. According to origin of germplasm resources, pharmic plant can be divided into four categories: local germplasm resources, foreign germplasm resources, wildlife resources, and artificially created germplasm resources. According to genetic relationship, pharmic plant is divided into primary gene pool (Gp-1), secondary gene pool (Gp-2), and tertiary gene pool (Gp-3), while based on the scope of the study area, it can be divided into regional and single type of germplasm resources.
