Southeast Asia is a centre of diversity of a number of tropical fruits, Indian sub continent comprising vast semi-arid and arid areas have enormous diversity of underutilized fruit species. A number of multipurpose tree species commonly grow as populations unattended in these inhospitable and stressed environments and also in the agricultural fields as isolated trees or in small groups. In most of the species no organized orcharding, nutritional management and plant protection practices are followed. These species have outstanding adaptation capabilities to drought tolerance, salt tolerance and are also resistant to major pest and diseases. Continued overexploitation of these species from natural habitats, increasing demand for land for agriculture and industry and least attention for this natural wealth has resulted in extensive degradation of their habitats.
