History
Although its botanical name ''Prunus persica'' refers to Persia, genetic studies suggest peaches originated in China, where they have been cultivated since the Neolithic period. Until recently, cultivation was believed to have started around 2000 BC. More recent evidence indicates that domestication occurred as early as 6000 BC in Zhejiang Province

Although Thomas Jefferson had peach trees at Monticello, American farmers did not begin commercial production until the 19th century in Maryland, Delaware, Georgia, South Carolina, and finally Virginia.

the peach tree genome (doubled haploid Lovell). Recently, it published the peach genome sequence and related analyses. The sequence is composed of 227 million nucleotides arranged in eight pseudomolecules representing the eight peach chromosomes (2n = 16). In addition, 27,852 protein-coding genes and 28,689 protein-coding transcripts were predicted.
Particular emphasis in this study is reserved for the analysis of the genetic diversity in peach germplasm and how it was shaped by human activities such as domestication and breeding. Major historical bottlenecks were found, one related to the putative original domestication that is supposed to have taken place in China about 4,000–5,000 years ago, the second is related to the western germplasm and is due to the early dissemination of the peach in Europe from China and the more recent breeding activities in the United States and Europe. These bottlenecks highlighted the substantial reduction of genetic diversity associated with domestication and breeding activities.
Cultivation
Peaches grow in a fairly limited range in dry, continental or temperate climates, since the trees have a chilling requirement

and on the timing of the cold, with the buds becoming less cold tolerant in late winter.
Another climate constraint is spring frost. The trees flower fairly early (in March in Western Europe), and the blossom is damaged or killed if temperatures drop below about . If the flowers are not fully open, though, they can tolerate a few degrees colder.
Climates with significant winter rainfall at temperatures below are also unsuitable for peach cultivation, as the rain promotes peach leaf curl, which is the most serious fungal disease for peaches. In practice, fungicides are extensively used for peach cultivation in such climates, with more than 1% of European peaches exceeding legal pesticide limits in 2013.
Finally, summer heat is required to mature the crop, with mean temperatures of the hottest month between .

Cultivars
Hundreds of peach and nectarine cultivars are known. These are classified into two categories—freestones and clingstones. Freestones are those whose flesh separates readily from the pit. Clingstones are those whose flesh clings tightly to the pit. Some cultivars are partially freestone and clingstone, so are called semifree. Freestone types are preferred for eating fresh, while clingstone types are for canning. The fruit flesh may be creamy white to deep yellow, to dark red; the hue and shade of the color depend on the cultivar.
Peach breeding has favored cultivars with more firmness, more red color, and shorter fuzz on the fruit surface. These characteristics ease shipping and supermarket sales by improving eye appeal. This selection process has not necessarily led to increased flavor, though. Peaches have a short shelf life, so commercial growers typically plant a mix of different cultivars to have fruit to ship all season long.
Different countries have different cultivars. In the United Kingdom, for example, these cultivars have gained the Royal Horticultural Society

Nectarines
The variety ''P. persica'' var. ''nucipersica'' (or var. ''nectarina'') – these are commonly called ''nectarines'' – has a smooth skin. It is on occasion referred to as a "shaved peach" or "fuzzless peach", due to its lack of fuzz or short hairs. Though fuzzy peaches and nectarines are regarded commercially as different fruits, with nectarines often erroneously believed to be a crossbreed between peaches and plum

s.
As with peaches, nectarines can be white or yellow, and clingstone or freestone. On average, nectarines are slightly smaller and sweeter than peaches, but with much overlap. The lack of skin fuzz can make nectarine skins appear more reddish than those of peaches, contributing to the fruit's plum-like appearance. The lack of down on nectarines' skin also means their skin is more easily bruised than peaches.
The history of the nectarine is unclear; the first recorded mention in English is from 1616, but they had probably been grown much earlier within the native range of the peach in central and eastern Asia. Although one source states that nectarines were introduced into the United States by David Fairchild
David Grandison Fairchild (April 7, 1869 – August 6, 1954) was an American botanist and plant explorer. Fairchild was responsible for the introduction of more than 200,000 exotic plants and varieties of established crops into the United State ...
of the Department of Agriculture in 1906, a number of colonial-era newspaper articles make reference to nectarines being grown in the United States prior to the Revolutionary War. The 28 March 1768 edition of the ''New York Gazette'' (p. 3), for example, mentions a farm in Jamaica, Long Island, New York, where nectarines were grown.
Peacherines
Peacherines are claimed to be a cross between a peach and a nectarine, but as they are the same species cannot be a true cross (hybrid); they are marketed in Australia and New Zealand. The fruit is intermediate in appearance, though, between a peach and a nectarine, large and brightly colored like a red peach. The flesh of the fruit is usually yellow, but white varieties also exist. The Koanga Institute lists varieties that ripen in the Southern Hemisphere in February and March.
In 1909, ''Pacific Monthly'' mentioned peacherines in a news bulletin for California. Louise Pound, in 1920, claimed the term peacherine is an example of language stunt.

Peach trees need full sun, and a layout that allows good natural air flow to assist the thermal environment for the tree. Peaches are planted in early winter. During the growth season, they need a regular and reliable supply of water, with higher amounts just before harvest.

The flowers on a peach tree are typically thinned out because if the full number of peaches mature on a branch, they are undersized and lack flavor. Fruits are thinned midway in the season by commercial growers. Fresh peaches are easily bruised, so do not store well. They are most flavorful when they ripen on the tree and are eaten the day of harvest.

On New Year's Eve, local magistrates would cut peach wood branches and place them over their doors to protect against evil influences. Peach wood was also used for the earliest known door god

For example, Tresidder claims the artists of Renaissance symbolically used peach to represent heart, and a leaf attached to the fruit as the symbol for tongue, thereby implying speaking truth from one's heart; a ripe peach was also a symbol to imply a ripe state of good health. Caravaggio's paintings introduce realism by painting peach leaves that are molted, discolored, or in some cases have wormholes – conditions common in modern peach cultivation.
