This list of sweet potato cultivars provides some information about varieties and cultivars of sweet potato (Ipomoea batatas). The sweet potato was first domesticated in the Americas more than 5,000 years ago. [1] As of 2013, there are approximately 7,000 sweet potato cultivars. People grow sweet potato in many parts of the world, including New Zealand, Australia, the Philippines, Japan, Hawaii, China, and North America. However, sweet potato is not widely cultivated in Europe. [2]

Contents

People breed sweet potatoes mainly either for food (their nutritious storage roots) or for their attractive vines. (The variety 'Vardaman' is grown for both.) The first table below lists sweet potato cultivars grown for their edible roots; the second table lists cultivars bred as ornamental vines. In the first table, the Parentage column briefly explains how the sweet potato cultivar was bred. Sweet potato plants with desirable traits are selectively bred to produce new cultivars.

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.

In the mid-20th century, sweet potato growers in the Southern United States began marketing orange-fleshed sweet potatoes as "yams", in an attempt to differentiate them from pale-fleshed sweet potatoes. [3] Even though these growers called their products yams, true yams are significantly different. All sweet potatoes are variations of one species: I. batatas. Yams are any of various tropical species of the genus Dioscorea . A yam tuber is starchier, dryer, and often larger than the storage root of a sweet potato, and the skin is more coarse. [3] This list does not include yams.

Cultivars bred for edible roots

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.

<span class="mw-page-title-main">Sweet potato</span> Species of edible plant

The sweet potato is a dicotyledonous plant that belongs to the bindweed or morning glory family, Convolvulaceae. Its large, starchy, sweet-tasting tuberous roots are used as a root vegetable. The young shoots and leaves are sometimes eaten as greens. Cultivars of the sweet potato have been bred to bear tubers with flesh and skin of various colors. Sweet potato is only distantly related to the common potato, both being in the order Solanales. Although darker sweet potatoes are often referred to as "yams" in parts of North America, the species is even more distant from the true yams, which are monocots in the order Dioscoreales.

<span class="mw-page-title-main">Root vegetable</span> Plant root used as a vegetable

Root vegetables are underground plant parts eaten by humans as food. In agricultural and culinary terminology, the term applies to true roots such as taproots and tuberous roots as well as non-roots such as bulbs, corms, rhizomes, and stem tubers.

<i>Oxalis tuberosa</i> Species of plant

Oxalis tuberosa is a perennial herbaceous plant that overwinters as underground stem tubers. These tubers are known as uqa in Quechua, oca in Spanish, yams in New Zealand and a number of other alternative names. The plant was brought into cultivation in the central and southern Andes for its tubers, which are used as a root vegetable. The plant is not known in the wild, but populations of wild Oxalis species that bear smaller tubers are known from four areas of the central Andean region. Oca was introduced to Europe in 1830 as a competitor to the potato, and to New Zealand as early as 1860.

<i>Dioscorea alata</i> Species of yam

Dioscorea alata – also called purple yam, ube, or greater yam, among many other names – is a species of yam. The tubers are usually a vivid violet-purple to bright lavender in color, but some range in color from cream to plain white. It is sometimes confused with taro and the Okinawa sweet potato beniimo (紅芋), however D. alata is also grown in Okinawa. With its origins in the Asian tropics, D. alata has been known to humans since ancient times.

<i>Ipomoea</i> Genus of flowering plants

Ipomoea is the largest genus in the plant family Convolvulaceae, with over 600 species. It is a large and diverse group, with common names including morning glory, water convolvulus or water spinach, sweet potato, bindweed, moonflower, etc. The genus occurs throughout the tropical and subtropical regions of the world, and comprises annual and perennial herbaceous plants, lianas, shrubs, and small trees; most of the species are twining climbing plants.

<i>Ullucus</i> Species of plant

Ullucus is a genus of flowering plants in the family Basellaceae, with one species, Ullucus tuberosus, a plant grown primarily as a root vegetable, secondarily as a leaf vegetable. The name ulluco is derived from the Quechua word ulluku, but depending on the region, it has many different names. These include illaco, melloco, chungua or ruba, olluco or papalisa, or ulluma.

<span class="mw-page-title-main">Kabocha</span> Type of winter squash

Kabocha is a type of winter squash, a Japanese variety of the species Cucurbita maxima. It is also called kabocha squash or Japanese pumpkin in North America. In Japan, "kabocha" may refer to either this squash, to the Western pumpkin, or indeed to other squashes. In Australia, "Japanese pumpkin" is a synonym of Kent pumpkin, a variety of winter squash.

<span class="mw-page-title-main">Yam (vegetable)</span> Edible starchy tuber

Yam is the common name for some plant species in the genus Dioscorea that form edible tubers.

<i>Agrius cingulata</i> Species of moth

Agrius cingulata, the pink-spotted hawkmoth or sweetpotato hornworm, is a moth in the family Sphingidae. The species was first described by Johan Christian Fabricius in 1775.

<i>Ipomoea pandurata</i> Species of flowering plant

Ipomoea pandurata, known as man of the earth, wild potato vine, manroot, wild sweet potato, and wild rhubarb, is a species of herbaceous perennial vine native to North America. It is a twining plant of woodland verges and rough places with heart-shaped leaves and funnel-shaped white flowers with a pinkish throat. The large tuberous roots can be roasted and eaten, or can be used to make a poultice or infusion. When uncooked, the roots have purgative properties.

Rhizopus soft rot is a disease of the sweet potato. It is one of the most common to affect the sweet potato, happening during packing and shipping. The disease causes a watery soft rot of the internal portion of the storage root. Strategies to manage the disease include the development of resistant varieties, curing through the use of heat and humidity, and application of decay control products.

The sweet potato is a very important crop for subsistence farmers in Africa and developing countries in other regions. Its relatively short growing period, tolerance to drought and high yield from poor soils lead to its use as a famine reserve for many of these households. However, it is a highly perishable food source that is susceptible to destruction by microorganisms, metabolic spoilage, physical destruction and pests. Therefore, it is not generally stored for long after harvest. This is a major barrier for the optimal use of the crop and causes much waste.

<span class="mw-page-title-main">Staple food</span> Food that is eaten routinely and considered a dominant portion of a standard diet

A staple food, food staple, or simply staple, is a food that is eaten often and in such quantities that it constitutes a dominant portion of a standard diet for an individual or a population group, supplying a large fraction of energy needs and generally forming a significant proportion of the intake of other nutrients as well. For humans, a staple food of a specific society may be eaten as often as every day or every meal, and most people live on a diet based on just a small variety of food staples. Specific staples vary from place to place, but typically are inexpensive or readily available foods that supply one or more of the macronutrients and micronutrients needed for survival and health: carbohydrates, proteins, fats, minerals, and vitamins. Typical examples include grains, seeds, nuts and root vegetables. Among them, cereals, legumes and tubers account for about 90% of the world's food calorie intake.

Purple sweet potato color (PSPC) is a natural anthocyanin food coloring obtained from the sweet potato. Some cultivars, like the Ayamurasaki, released in Japan in 1995, are specially developed to have a higher anthocyanin content.

<span class="mw-page-title-main">Honeynut squash</span> Miniature winter squash

Honeynut squash is an interspecific hybrid winter squash cultivar bred from butternut and buttercup squash. It has dark tan to orange skin with orange fleshy pulp. When ripe, it turns from green to a deep orange and becomes sweeter and richer. Honeynut squash has a similar shape and flavor to butternut squash but averages about half the size and is sweeter. It has two to three times more beta-carotene than butternut squash. Honeynut squash can be roasted, sautéed, puréed, added to soups, stews, and braises, and has enough sugar content for desserts.

<span class="mw-page-title-main">Sweet potato cultivation in Polynesia</span> Agricultural practice

Sweet potato cultivation in Polynesia as a crop began around 1000 AD in central Polynesia. The plant became a common food across the region, especially in Hawaii, Easter Island and New Zealand, where it became a staple food. By the 17th century in central Polynesia, traditional cultivars were being replaced with hardier and larger varieties from the Americas. Many traditional cultivars are still grown across Polynesia, but they are rare and are not widely commercially grown.

Ipomoea aequatoriensis is a morning glory plant which was first scientifically described in 2022, and is the closest wild relative to the sweet potato known to science. The evolution of the sweet potato has always been a mystery, however with the discovery of this new plant, the history has become a bit clearer. The newly found plant was discovered by an Oxford University team of researchers led by Dr. Pablo Muńoz-Rodríguez. The plant was "stumbled upon" when the team was looking at herbarium specimens that had been collected of the plant Ipomoea batatas when researchers realized that one of the collected specimens differed in sepals and other characteristics.
