Sweetpotato, Ipomoea batatas (L.) Lam. (family Convolvulaceae), ranks as the world’s third most important root crop after potato and cassava. The global annual production of sweetpotato is approximately 128 million tons on 8 million hectares, of which over 90% is in developing countries. In countries surrounding the Lake Victoria basin of East Africa, the crop is essential mostly as a “famine reserve” crop. Its suitability for piece-meal harvesting, high performance in marginal soils, adaptability to abiotic stresses such as drought, resistance to most pests and diseases, and high content of vitamin A in orange-fleshed cultivars make it an ideal staple crop in subsistence economies. However, processed products, biscuits, and other fashionable foods made of the orange-fleshed sweetpotato are also entering markets and elevate the status of sweetpotato among local consumers.
