There are many different types of genetic resources that may be used for different purposes. For example, categories of plant genetic resources for food and agriculture may include wild species, wild relatives of crop species, landraces, primitive and obsolete varieties, modern varieties, breeding lines and experimental populations, and lines with specific genetic characteristics. Many other types of genetic resources are used for such purposes as pharmaceutical development, traditional medicine, horticulture, personal care and cosmetics, foods or beverages, or environmental remediation.
