Wild species tomatoes are distributed in the Pacific coast and the Galapagos Islands in the Andes mountains of South America,and many of the native areas create their own diverse ecosystems in arid and semi-arid areas. Although these are very important　traits in the use of tomatoes, they are a valuable genetic resource for the improvement of varieties, but their traits and physiological　characteristics are hardly known. On the other hand, the species itself is endangered by the global environmental change and human　development, and the disappearance of the native land itself is feared. In addition, international law is applied, and the introductionand the use from the wild land are restricted. In this paper, we detail the characteristics of species of wild species tomatoes and outline the conservation and use rules of genetic resources.
