摘要
Sweetpotato (Ipomoea batatas L. Lam) is a tuber crop of immense potential as it produces more edible energy on marginal land than any other major food crop. As well as this useful property it can withstand adverse abiotic and biotic stresses and does not require intensive care. It therefore plays an important role in the economy of poor households where it acts as a major source of subsistence and is considered to be a ‘famine relief crop’. Besides this important function, the crop has immense industrial value for extraction of starch and production of animal feed. For all these reasons sweetpotato has great possibilities for enhancing food and nutrition security in developing and underdeveloped countries where most of the farmers’ holdings belong to the small and marginal categories. Although the crop is assuming greater significance owing to the ever-increasing population its importance is still underestimated and, unlike most staples, fails to attract sufficient attention of agricultural researchers throughout the tropics and subtropics. With greater attention and more collaborative research, there could be considerable improvements in the genetics of the crop and its husbandry which, together, would allow it to fulfill a wide range of needs in these areas of the world.
