Sweet potato cultivars differ in many ways. One way people compare them is by the size, shape, and color of the roots. The more orange the flesh of a sweet potato root is, the more nutritious carotene it has. (Humans metabolize carotene into vitamin A.) The skin of a sweet potato root is a different color than the flesh. The biological word for the outer skin is epidermis; the flesh is called the pith or medulla. The first table below has a general description of the color of the root's flesh and skin.
Many of the sweet potato cultivars below were bred at agricultural experiment stations. An agricultural experiment station (AES) is a research center where scientists work to increase the quality and quantity of food production. Agricultural experiment stations are usually operated by a government agency and/or a university.
