This is a list of Capsicum cultivars belonging to the five major species of cultivated peppers (genus Capsicum ): C. annuum , C. chinense , C. baccatum , C. frutescens , and C. pubescens . Due to the large and changing number of cultivars, and the variation of cultivar namings in different regions, this list only gives a few examples of the estimated 5000 pepper varieties that exist.
There are perhaps fifty thousand Capsicum cultivars grown worldwide. [1] The USDA-ARS GRIN seed collection contains 6,200 Capsicum accessions alone, including 4,000 Capsicum annuum accessions. The other Capsicum species in the USDA germplasm repository include: C. chinense, C. baccatum, C. frutescens, C. pubescens, C. cardenasii, C. chacoense, C. flexuosum, C. eximium, C. rhomboideum, C. galapagoense, and C. tovarii. [2]
There are five major species of cultivated Capsicum , C. annuum, C. chinense, C. baccatum, C. frutescens, C. pubescens , and within those species are several "taxonomic varieties". Because of the ability of many of species to cross and generate inter-specific hybrids, albeit with low success, there are also what is referred to as "complexes" within the genus Capsicum of closely related and sexually compatible species. [3] This includes the Capsicum annuum complex, which consists of C. annuum, C. frutescens, and C. chinense.[ citation needed ]
Major species and their taxonomic varieties: [4]
The species and varieties include many economically important cultivars with a variety of different shapes, colors, and flavors that are grown for different purposes, such as spices, vegetables, and herbal medicines. Some confusion has resulted from the legal term "plant variety", which is used interchangeably with "cultivar" (not with "taxonomic variety"). The terminology around a cultivar also includes terms such as heirloom, open-pollinated, self-pollinating, and hybrid. [9]
Heirloom varieties are typically those that have been selected and grown historically with seeds saved every year, and are still maintained today in similar fashion, such as the blocky-type California Wonder. Open-pollinated varieties are those that are maintained without strict barriers to prevent outcrossing and then seed is collected at and stored from each harvest such as the lamuyo-type Marconi Yellow. While open-pollinated varieties are typically true-to-type, there may be occasional outcrossing to other Capsicum varieties that may introduce some heterogeneity. Self-pollinated varieties are similar to open-pollinated varieties in that they are true-to-type and seed is collected at and stored from each harvest, but measures are taken to minimize outcrossing. This may involve placing a barrier such as a mesh bag or cage over the plant to prevent pollinators from reaching flowers, ensuring that the plant has "selfed". This is how much seed intended for home-garden use is produced, like the cultivar Early Jalapeño. These three types of cultivar seed production are all similar in that only one parent is used and the seed are produced generally through self-pollination.
Hybrid varieties take advantage of a phenomenon called heterosis or hybrid vigor, which occurs in pepper. To generate a hybrid variety, two self-pollinated varieties are intentionally crossed, and all seed from this cross are collected. The new hybrid variety typically is more vigorous than either of the two parents contributing to traits such as higher yield. [9] Inter-specific crossing may result in a hybrid of diminished fertility due to specific genetic incompatibilities. In some cases, this may be overcome by deliberately selecting which of the two parents is to be the female parent in the cross. [10] Hybrid seed if saved will not produce a homogeneous set of plants the next generation, meaning that the two parents will need to be crossed again to generate more hybrid seed. This method is used to produce hybrid Capsicum cultivars such as the blocky types Double-Up and Orange Blaze. Much of the commercial pepper production uses hybrid varieties for their improved traits.
Capsicum annuum, native from southern North America through Central America to South America, has been cultivated by Indigenous peoples of the Americas for thousands of years, and globally for over 400 years. [11] Its fruit forms are varied, from large to small, sweet to sour, and very hot/pungent to bland. Despite being a single species, C. annuum has many forms, with a variety of names, even in the same language. Official names aside, in American English, any variety lacking heat is colloquially known as a sweet pepper, and those sweet peppers that have a blocky shape are referred to as bell peppers. A variety that produces capsaicin is colloquially known as a hot pepper or chili pepper. In British English, the sweet varieties are called "peppers" [12] and the hot varieties "chillies", [13] whereas in Australian English and Indian English, the name "capsicum" is commonly used for bell peppers exclusively and "chilli" is often used to encompass the hotter varieties.
The plant is a tender perennial subshrub, with a densely branched stem. The plant reaches 0.5–1.5 m (20–59 in). Single white flowers develop into the fruit, which is typically green when unripe, but may lack chlorophyll causing a white color. Ripening fruits usually change to red, although some varieties may ripen to yellow, orange, peach, brown, or purple. The species are grown in temperate climates as an annual, but they are especially productive in warm and dry climates. [14]

Capsicum chinense or "Chinese capsicum" is a misnomer since all Capsicum species originated in the New World. Nikolaus Joseph von Jacquin (1727–1817), a Dutch botanist, named the species in that way in 1776 because he believed they originated in China. Most of the peppers of this species have a distinctive flavor and are similar in flavor to each other.[ citation needed ]

Chili peppers, also spelled chile or chilli, are varieties of the berry-fruit of plants from the genus Capsicum, which are members of the nightshade family Solanaceae, cultivated for their pungency. Chili peppers are widely used in many cuisines as a spice to add "heat" to dishes. Capsaicin and related compounds known as capsaicinoids are the substances that give chili peppers their intensity when ingested or applied topically. Chili peppers exhibit a range of heat and flavors. This diversity is the reason behind the availability of different types of paprika and chili powder, each offering its own taste and heat level.
Malagueta pepper, a variety of Capsicum frutescens, is a type of chili pepper widely used in the Portuguese-speaking world and the Caribbean. It got its name from the unrelated melegueta pepper, an African spice from Guinea which is a member of the ginger family.
Capsicum pubescens is a plant of the genus Capsicum (pepper). The species name, pubescens, refers to the hairy leaves of this pepper. The hairiness of the leaves, along with the black seeds, make Capsicum pubescens distinguishable from other Capsicum species. Capsicum pubescens has pungent yellow, orange, red, green or brown fruits.
Capsicum annuum, commonly known as paprika, chili pepper, red pepper, sweet pepper, jalapeño, cayenne, or bell pepper, is a fruiting plant from the family Solanaceae (nightshades), within the genus Capsicum which is native to the northern regions of South America and to southwestern North America. The plant produces berries of many colors including red, green, and yellow, often with pungent taste. It is also one of the oldest cultivated crops, with domestication dating back to around 6,000 years ago in regions of Mexico. The genus Capsicum has over 30 species but Capsicum annuum is the primary species in its genus, as it has been widely cultivated for human consumption for a substantial amount of time and has spread across the world. This species has many uses in culinary applications, medicine, self defense, and can even be ornamental.
Capsicum frutescens is a wild chili pepper having genetic proximity to the cultivated pepper Capsicum chinense native to Central and South America. Pepper cultivars of C. frutescens can be annual or short-lived perennial plants. Flowers are white with a greenish white or greenish yellow corolla, and are either insect- or self-pollinated. The plants' berries typically grow erect; ellipsoid-conical to lanceoloid shaped. They are usually very small and pungent, growing 10–20 millimetres (0.39–0.79 in) long and 3–7 millimetres (0.12–0.28 in) in diameter. Fruit typically grows a pale yellow and matures to a bright red, but can also be other colors. C. frutescens has a smaller variety of shapes compared to other Capsicum species. C. frutescens has been bred to produce ornamental strains because of its large quantities of erect peppers growing in colorful ripening patterns.
Capsicum chinense, commonly known as a "habanero-type pepper", is a species of chili pepper native to the Americas. C. chinense varieties are well known for their unique flavors and, in many cases, exceptional heat. The hottest peppers in the world are members of this species, with a Scoville Heat Unit score of 2.69 million measured in the C. chinense cultivar, Pepper X in 2023.
Pequinpepper is a hot chili pepper cultivar commonly used as a spice. Pequin peppers are very hot, often 5–8 times hotter than jalapeños on the Scoville scale. Flavor is described as citrusy and nutty.
The tabasco pepper is a variety of the chili pepper species Capsicum frutescens originating in Mexico. It is best known through its use in Tabasco sauce, followed by peppered vinegar.
Capsicum baccatum is a member of the genus Capsicum, and is one of the five domesticated chili pepper species. The fruit tends to be very pungent, and registers 30,000 to 50,000 on the Scoville heat unit scale.
Siling labuyo is a small chili pepper cultivar that developed in the Philippines after the Columbian Exchange. It belongs to the species Capsicum frutescens and is characterized by triangular fruits that grow pointing upwards. The fruits and leaves are used in traditional Philippine cuisine. The fruit is pungent, ranking at 80,000 to 100,000 heat units in the Scoville Scale.
Colletotrichum capsici is a species of fungus and plant pathogen which causes leaf blight on Chlorophytum borivilianum, basil, chickpea and pepper as well as dieback in pigeonpea and anthracnose in poinsettia.
The Lemon Drop pepper, Ají Limón or Ají Limo, is a hot, citrus-like, lemon-flavored pepper which is a popular seasoning pepper in Peru, where it is known as qillu uchu. A member of the baccatum species, the lemon drop is a cone pepper that is around 60–80 mm (2.4–3.1 in) long and 12 mm (0.47 in) wide with some crinkling.
The peter pepper, Capsicum annuum var. annuum, is an heirloom chili pepper that is best known for its unusual shape. It is a type of Capsicum annuum, though it is not officially recognized as a cultivar of the species. It occurs in red and yellow varieties. The pepper is considered very rare and its origin is unknown.
Dundicut peppers are a variety of small, round, dark red chili peppers grown in Sindh, in Pakistan, Sikkim in India and Ilam in Nepal. They are a cultivar of either Capsicum frutescens or Capsicum annuum and are also known in Asia as gol lal mirch. Sold dried, Dundicuts are similar in size and flavor to Scotch bonnet peppers, but are not as hot, and are of a different species.
The ghost pepper, also known as bhüt jolokia, is an interspecific hybrid chili pepper cultivated in Northeast India. It is a hybrid of Capsicum chinense and Capsicum frutescens.
Bird's eye chili or Thai chili is a chili pepper variety from the species Capsicum annuum that is native to Mexico. Cultivated across Southeast Asia, it is used extensively in many Asian cuisines. It may be mistaken for a similar-looking chili derived from the species Capsicum frutescens, the cultivar siling labuyo. Capsicum frutescens fruits are generally smaller and characteristically point upwards. In the Marianas and Guam these are often called boonie peppers or Doni Sali, which can be term for regional wild varieties. The variation between different varieties can be significant for regional dishes or visuals, such as the Thai ornamental varieties.
Capsicum is a genus of flowering plants in the nightshade family Solanaceae, native to the Americas, cultivated worldwide for their edible fruit, which are generally known as "peppers" or "capsicum". Sweet or bell peppers and some chili peppers belong to the Capsicum annuum species, making it the most cultivated species from the genus.
The cayenne pepper is a type of Capsicum annuum. It is usually a hot chili pepper used to flavor dishes. Cayenne peppers are a group of tapering, 10 to 25 cm long, generally skinny, mostly red-colored peppers, often with a curved tip and somewhat rippled skin, which hang from the bush as opposed to growing upright. Most varieties are generally rated at 30,000 to 50,000 Scoville units.
The habanero is a hot variety of chili. Unripe habaneros are green, and they color as they mature. The most common color variants are orange and red, but the fruit may also be white, brown, yellow, green, or purple. Typically, a ripe habanero is 2–6 centimetres long. Habanero chilis are very hot, rated 100,000–350,000 on the Scoville scale. The habanero heat, flavor, and floral aroma make it a common ingredient in hot sauces and other spicy foods.
The Sandia pepper or Sandia chile pepper is a New Mexico chile pepper cultivar of the species Capsicum annuum with a scoville rating which ranges from mild to hot. This cultivar is extensively grown in New Mexico where it was developed and is popular in New Mexican cuisine. Sandia peppers picked while still green are typically roasted to produce green chile. When ripened, this variety can be dried and ground to make chile powder. Sandia peppers grown and consumed in New Mexico are most commonly used to make red or green posole, green chile stew, and carne adovada.
