List of Capsicum cultivars
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 50,000 pepper varieties that exist.
There are perhaps fifty thousand Capsicum cultivars grown worldwide. The USDA-ARS GRIN seed collection contains 6,200 Capsicum accessions alone, which include 4000 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. 
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. This includes the Capsicum annuum complex, which consists of C. annuum, C. frutescens, and C. chinense.
Major species and their taxonomic varieties:
- Capsicum annuum, which includes bell peppers, sweet/Italian peppers, serrano, cayenne, paprika and jalapeños
- Capsicum baccatum, which includes the South American varieties, such as ají amarillo, ají limon and criolla sella
- Capsicum chinense, which includes all of the Habaneros, Scotch Bonnets, Trinidad Scorpions, the Bhut Jolokia and the Carolina Reaper.
- Capsicum frutescens, which includes the Tabascos and many of the peppers grown in India; sometimes not distinguished as a species separate from C. annuum.
- Capsicum pubescens, which includes the Rocoto and Manzano pepper, and are distinctive plants in having violet flowers, black seeds and hairy dark green leaves and grows as a large, multi-stemmed vine up to 5 meters long.
The species and varieties include many economically important cultivars with 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-pollinated, and hybrid.
Heirloom varieties are typically those that have been selected and grown historically with seed 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 out-crossing 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 out-crossing 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 out-crossing. 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 selfing.
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. 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 worldwide for over 400 years. 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" and the hot varieties "chillies", whereas in Australian 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 (20–60 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.

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.
