86-515: The Granny Smith , also known as a green apple or sour apple , is an apple cultivar that originated in Australia in 1868. It is named after Maria Ann Smith, who propagated the cultivar from a chance seedling . The tree is thought to be a hybrid of Malus sylvestris , the European wild apple, with the domesticated apple Malus domestica as the polleniser . The fruit is hard, firm and with

172-573: A Human Development Index (HDI) of 0.946, the tenth-highest in the world as of the 2024 report. New Zealand is also well developed, with a nominal GDP per capita of US$ 48,072 and an HDI of 0.939, putting it at number 16 in the world in 2024. The least developed nations in the Southern Hemisphere cluster in Africa and Oceania, with Mozambique and Burundi at the lowest ends of the HDI, at 0.461 (number 183 in

258-496: A chance seedling that had sprung near a creek. Smith had dumped there, among the ferns, the remains of French crab-apples that had been grown in Tasmania . Another story recounted that Smith had been testing French crab-apples for cooking, and, throwing the apple cores out her window as she worked, had found that the new cultivar had sprung up underneath her kitchen windowsill. Whatever the case, Smith took it upon herself to propagate

344-537: A 2013 set of four 33¢ stamps commemorating historic strains, joined by Northern Spy , Baldwin , and Golden Delicious . Apple An apple is a round, edible fruit produced by an apple tree ( Malus spp. , among them the domestic or orchard apple ; Malus domestica ). Apple trees are cultivated worldwide and are the most widely grown species in the genus Malus . The tree originated in Central Asia , where its wild ancestor, Malus sieversii ,

430-402: A bed of straw, chaff, or mats with windfalls kept separately. Though methods like this will extend the availabity of reasonably fresh apples, without refrigeration their lifespan is limited. Even sturdy winter apple varieties will only keep well until December in cool climates. For longer storage medieval Europeans strung up cored and peeled apples to dry, either whole or sliced into rings. Of

516-634: A light green skin and crisp, juicy flesh. The flavour is tart and acidic. It remains firm when baked, making it a popular cooking apple used in pies, where it can be sweetened. The apple goes from being completely green to turning yellow when overripe. The US Apple Association reported in 2019 that the Granny Smith was the third most popular apple in the United States of America. The Granny Smith cultivar originated in Eastwood, New South Wales , Australia (now

602-420: A long period of time and permitted secondary introgression of genes from other species into the open-pollinated seeds. Significant exchange with Malus sylvestris , the crabapple, resulted in populations of apples being more related to crabapples than to the more morphologically similar progenitor Malus sieversii . In strains without recent admixture the contribution of the latter predominates. The apple

Some varieties of apples (e.g. ' Granny Smith ' and ' Fuji ') have more than three times the storage life of others. Non-organic apples may be sprayed with a substance 1-methylcyclopropene blocking the apples' ethylene receptors, temporarily preventing them from ripening. Apple trees are susceptible to fungal and bacterial diseases, and to damage by insect pests. Many commercial orchards pursue

774-447: A program of chemical sprays to maintain high fruit quality, tree health, and high yields. These prohibit the use of synthetic pesticides, though some older pesticides are allowed. Organic methods include, for instance, introducing its natural predator to reduce the population of a particular pest. A wide range of pests and diseases can affect the plant. Three of the more common diseases or pests are mildew, aphids, and apple scab. Among

860-459: A rounded to erect crown with a dense canopy of leaves. The bark of the trunk is dark gray or gray-brown, but young branches are reddish or dark-brown with a smooth texture. Young twigs are covered in fine downy hairs; they become hairless when older. The buds are egg-shaped and dark red or purple in color; they range in size from 3 to 5 millimeters, but are usually less than 4 mm. The bud scales have very hairy edges. When emerging from

946-409: A species has more than 100 alternative scientific names, or synonyms . In modern times, Malus pumila and Malus domestica are the two main names in use. M. pumila is the older name, but M. domestica has become much more commonly used starting in the 21st century, especially in the western world. Two proposals were made to make M. domestica a conserved name : the earlier proposal

1032-552: A strong minority following. Extremely sweet apples with barely any acid flavor are popular in Asia, especially the Indian subcontinent . Old cultivars are often oddly shaped, russeted, and grow in a variety of textures and colors. Some find them to have better flavor than modern cultivars, but they may have other problems that make them commercially unviable—low yield, disease susceptibility, poor tolerance for storage or transport, or just being

They purchased a small orchard in the area in 1855–1856 and began cultivating fruit, for which the area was a well known centre in colonial Australia . Smith had eight children and was a prominent figure in the district, earning

1204-417: A year. This cultivar needs fewer winter chill hours and a longer season to mature the fruit, so it is favoured for the milder areas of the apple growing regions. However, they are susceptible to superficial scald and bitter pit. Superficial scald may be controlled by treatment with diphenylamine before storage. It can also be controlled with low-oxygen storage. Pit can be controlled with calcium sprays during

1290-477: Is generally considered the center of origin for apples due to the genetic variability in specimens there. The wild ancestor of Malus domestica was Malus sieversii , found growing wild in the mountains of Central Asia in southern Kazakhstan , Kyrgyzstan , Tajikistan , and northwestern China . Cultivation of the species, most likely beginning on the forested flanks of the Tian Shan mountains, progressed over

1376-562: Is generally pale yellowish-white, though it can be pink, yellow or green. Important volatile compounds in apples that contribute to their scent and flavour include acetaldehyde , ethyl acetate , 1-butanal , ethanol , 2-methylbutanal, 3-methylbutanal , ethyl propionate , ethyl 2-methylpropionate, ethyl butyrate , ethyl 2-methyl butyrate, hexanal , 1-butanol , 3-methylbutyl acetate , 2-methylbutyl acetate, 1-propyl butyrate, ethyl pentanoate , amyl acetate , 2-methyl-1-butanol , trans-2-hexenal, ethyl hexanoate , hexanol . The apple as

There is indirect evidence of apple cultivation in the third millennium BCE in the Middle East . There is direct evidence, apple cores, dated to the 10th century BCE from a Judean site between the Sinai and Negev. There was substantial apple production in European classical antiquity, and grafting

1548-667: Is located in the Southern Hemisphere, and it is deemed by the International Hydrographic Organization as being wholly within the South Pacific Ocean, rather than the North Pacific. More than 850 million people live in the Southern Hemisphere, representing around 10–12% of the total global human population. Of those 850 million people, more than 203 million live in Brazil , the largest country by land area in

1634-449: Is moderately susceptible to fire blight and is very prone to scab , powdery mildew , and cedar apple rust . Granny Smith is much more easily preserved in storage than other apples, a factor which has greatly contributed to its success in export markets. Its long storage life has been attributed to its fairly low levels of ethylene production, and in the right conditions Granny Smiths can be stored without loss of quality for as long as

1720-479: Is mostly concentrated on/around the islands of Bali , Mauritius , and Fiji . The oldest continuously inhabited city in the Southern Hemisphere is Bogor , in western Java , which was founded in 669 . Ancient texts from the Hindu kingdoms prevalent in the area definitively record 669 CE as the year when Bogor was founded. However, some evidence shows that Zanzibar , an ancient port with around 200,000 inhabitants off

The overcolor of ripe apples can be orange-red, pink-red, red, purple-red or brown-red. The overcolor amount can be 0–100%. The skin may be wholly or partly russeted , making it rough and brown. The skin is covered in a protective layer of epicuticular wax . The skin may also be marked with scattered dots. The flesh

1978-725: Is still found. Apples have been grown for thousands of years in Eurasia and were introduced to North America by European colonists . Apples have religious and mythological significance in many cultures, including Norse , Greek , and European Christian tradition. Apples grown from seed tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. For commercial purposes, including botanical evaluation, apple cultivars are propagated by clonal grafting onto rootstocks . Apple trees grown without rootstocks tend to be larger and much slower to fruit after planting. Rootstocks are used to control

2150-582: Is thought to have been domesticated 4,000–10,000 years ago in the Tian Shan mountains, and then to have travelled along the Silk Road to Europe, with hybridization and introgression of wild crabapples from Siberia ( M. baccata ), the Caucasus ( M. orientalis ), and Europe ( M. sylvestris ). Only the M. sieversii trees growing on the western side of the Tian Shan mountains contributed genetically to

2236-742: The Age of Discovery , the Southern Hemisphere was largely cut off from the cultural constructs of the Western and Eastern worlds . Some view both the West and the East as being Northern Hemisphere-centric concepts. The most widespread religions in the modern Southern Hemisphere are Christianity , prevalent in South America, Africa, Oceania, and East Timor , followed by Islam in East Africa and Indonesia , and Hinduism , which

These civilizations built cities, pyramids, and plazas in the coastal river valleys of northern Peru with some ruins dating back to 3600 BCE . Easter Island , located about 3,500 kilometres from Chile and French Polynesia , is considered to be the most remote place on Earth to have been permanently inhabited by humans before

2408-615: The Northern Hemisphere , except in the Antarctic which is colder than the Arctic . This is because the Southern Hemisphere has significantly more ocean and much less land; water heats up and cools down more slowly than land. The differences are also attributed to oceanic heat transfer and differing extents of greenhouse trapping. In the Southern Hemisphere, the Sun passes from east to west through

During solar eclipses viewed from a point to the south of the Tropic of Capricorn, the Moon moves from left to right on the disc of the Sun (see, for example, photos with timings of the solar eclipse of November 13, 2012 ), while viewed from a point to the north of the Tropic of Cancer (i.e., in the Northern Hemisphere), the Moon moves from right to left during solar eclipses. The Coriolis effect causes cyclones and tropical storms to spin clockwise in

2580-460: The apple clearwing moth (red-belted clearwing) burrow through the bark and into the phloem of apple trees, potentially causing significant damage. There are more than 7,500 known cultivars (cultivated varieties) of apples. Cultivars vary in their yield and the ultimate size of the tree, even when grown on the same rootstock . Different cultivars are available for temperate and subtropical climates. The UK's National Fruit Collection, which

2666-487: The petals are rose-pink and fade to white or light pink when fully open with each flower 3-to-4-centimeter (1-to- 1 + 1 ⁄ 2 -inch) in diameter. The five-petaled flowers are group in an inflorescence consisting of a cyme with 3–7 flowers. The central flower of the inflorescence is called the "king bloom"; it opens first and can develop a larger fruit. Open apple blossoms are damaged by even brief exposures to temperatures −2 °C (28 °F) or less, although

2752-541: The "best" cultivars, showing the proliferation of new North American cultivars by the early 19th century. In the 20th century, irrigation projects in Eastern Washington began and allowed the development of the multibillion-dollar fruit industry, of which the apple is the leading product. Until the 20th century, farmers stored apples in frostproof cellars during the winter for their own use or for sale. Improved transportation of fresh apples by train and road replaced

2838-718: The "wrong" size. A few old cultivars are still produced on a large scale, but many have been preserved by home gardeners and farmers that sell directly to local markets. Many unusual and locally important cultivars with their own unique taste and appearance exist; apple conservation campaigns have sprung up around the world to preserve such local cultivars from extinction. In the United Kingdom, old cultivars such as ' Cox's Orange Pippin ' and ' Egremont Russet ' are still commercially important even though by modern standards they are low yielding and susceptible to disease. 2022, millions of tonnes Southern Hemisphere Owing to

Unusually for a popular cultivar, the 'Honeycrisp' is not directly related to another popular apple cultivar but instead to two unsuccessful cultivars. In Europe there are also many breeding programs such as the Julius Kühn-Institut ,

3010-444: The 14th-century Middle English expression appel of paradis , meaning a banana . The apple is a deciduous tree, generally standing 2 to 4.5 metres (6 to 15 feet) tall in cultivation and up to 15 m (49 ft) in the wild, though more typically 2 to 10 m (6.5 to 33 ft). When cultivated, the size, shape and branch density are determined by rootstock selection and trimming method. Apple trees may naturally have

3096-806: The 15th century and later went through several cycles of popularity and decline throughout the world. The majority of the rootstocks used to control size in apples were developed in England in the early 1900s. The East Malling Research Station conducted extensive research into rootstocks, and their rootstocks are given an "M" prefix to designate their origin. Rootstocks marked with an "MM" prefix are Malling-series cultivars later crossed with trees of ' Northern Spy ' in Merton, England . Most new apple cultivars originate as seedlings, which either arise by chance or are bred by deliberately crossing cultivars with promising characteristics. The words "seedling", "pippin", and "kernel" in

Other desirable qualities in modern commercial apple breeding are a colorful skin, absence of russeting , ease of shipping, lengthy storage ability, high yields, disease resistance, common apple shape, and developed flavor. Modern apples are generally sweeter than older cultivars, as popular tastes in apples have varied over time. Most North Americans and Europeans favor sweet, subacid apples, but tart apples have

3354-628: The Granny Smith apple is now celebrated annually in Eastwood with the Granny Smith Festival . Granny Smith apples are light green in colour. The tart flavor of these apples makes them one of the most versatile varieties of apple to cook with. They are popularly used in many apple dishes , such as apple pie , apple cobbler , apple crumble , and apple cake . They are also commonly eaten raw as table apples , and at least one company ( Woodchuck Hard Cider ) makes Granny Smith varietal cider . It

The UK's national fruit collection database contains much information on the characteristics and origin of many apples, including alternative names for what is essentially the same "genetic" apple cultivar. Most of these cultivars are bred for eating fresh (dessert apples), though some are cultivated specifically for cooking ( cooking apples ) or producing cider . Cider apples are typically too tart and astringent to eat fresh, but they give

4042-404: The average 30-day blossom period, with pollinizers selected from cultivars within a 6-day overlap period. There are four to seven pollination groups in apples, depending on climate: One cultivar can be pollinated by a compatible cultivar from the same group or close (A with A, or A with B, but not A with C or D). Cultivars vary in their yield and the ultimate size of the tree, even when grown on

4128-431: The base of the flower. The seeds are egg- to pear-shaped and may be colored from light brown or tan to a very dark brown, often with red shades or even purplish-black. They may have a blunt or sharp point. The five sepals remain attached and stand out from the surface of the apple. The size of the fruit varies widely between cultivars, but generally has a diameter between 2.5 and 12 cm (1 and 5 in). The shape

4214-475: The beverage a rich flavor that dessert apples cannot. In the United States there are many apple breeding programs associated with universities. Cornell University has had a program operating since 1880 in Geneva, New York . Among their recent well known apples is the 'SnapDragon' cultivar released in 2013. In the west Washington State University started a program to support their apple industry in 1994 and released

4300-694: The branches. Trees grafted on dwarfing rootstocks bear about 10–80 kg (20–180 lb) of fruit per year. Some farms with apple orchards open them to the public so consumers can pick their own apples. Crops ripen at different times of the year according to the cultivar. Cultivar that yield their crop in the summer include ' Sweet Bough ' and 'Duchess'; fall producers include 'Blenheim'; winter producers include 'King', ' Swayzie ', and 'Tolman Sweet'. Commercially, apples can be stored for months in controlled atmosphere chambers. Apples are commonly stored in chambers with lowered concentrations of oxygen to reduce respiration and slow softening and other changes if

4472-453: The case when a triploid plant can produce a seed (apples are an example), it occurs infrequently, and seedlings rarely survive. Because apples are not true breeders when planted as seeds, propagation usually involves grafting of cuttings. The rootstock used for the bottom of the graft can be selected to produce trees of a large variety of sizes, as well as changing the winter hardiness, insect and disease resistance, and soil preference of

4558-410: The characteristics of the parent. This is because seedling apples are " extreme heterozygotes ". Rather than resembling their parents, seedlings are all different from each other and from their parents. Triploid cultivars have an additional reproductive barrier in that three sets of chromosomes cannot be divided evenly during meiosis, yielding unequal segregation of the chromosomes (aneuploids).

The oldest monumental civilizations in the Southern Hemisphere are

4730-572: The domesticated apple, not the isolated population on the eastern side. Chinese soft apples, such as M. asiatica and M. prunifolia , have been cultivated as dessert apples for more than 2,000 years in China. These are thought to be hybrids between M. baccata and M. sieversii in Kazakhstan. Among the traits selected for by human growers are size, fruit acidity, color, firmness, and soluble sugar. Unusually for domesticated fruits,

4816-400: The flowering each season, apple growers often utilize pollinators to carry pollen. Honey bees are most commonly used. Orchard mason bees are also used as supplemental pollinators in commercial orchards. Bumblebee queens are sometimes present in orchards, but not usually in sufficient number to be significant pollinators. Cultivars are sometimes classified by the day of peak bloom in

4902-437: The following years the government actively promoted the apple, leading to its widespread adoption. Its worldwide fame grew from the fact that it could be picked from March and stored till November. Enterprising fruit merchants in the 1890s and the 1900s experimented with methods to transport the apples overseas in cold storage. Because of its excellent shelf life , the Granny Smith could be exported long distances and most times of

4988-483: The fruit is already fully ripe. The gas ethylene is used by plants as a hormone which promotes ripening, decreasing the time an apple can be stored. For storage longer than about six months the apples are picked earlier, before full ripeness, when ethylene production by the fruit is low. However, in many varieties this increases their sensitivity to carbon dioxide , which also must be controlled. For home storage, most culitvars of apple can be stored for three weeks in

5074-495: The fruit's genome was sequenced as part of research on disease control and selective breeding in apple production. The word apple , whose Old English ancestor is æppel , is descended from the Proto-Germanic noun * aplaz , descended in turn from Proto-Indo-European * h₂ébōl . As late as the 17th century, the word also functioned as a generic term for all fruit, including nuts . This can be compared to

The leaves are attached alternately by short leaf stems 1-to-3.5 cm ( 1 ⁄ 2 -to- 1 + 1 ⁄ 2  in) long. Blossoms are produced in spring simultaneously with the budding of the leaves and are produced on spurs and some long shoots . When the flower buds first begin to open

5418-680: The many Old World plants that the Spanish introduced to Chiloé Archipelago in the 16th century, apple trees became particularly well adapted. Apples were introduced to North America by colonists in the 17th century, and the first named apple cultivar was introduced in Boston by Reverend William Blaxton in 1640. The only apples native to North America are crab apples . Apple cultivars brought as seed from Europe were spread along Native American trade routes, as well as being cultivated on colonial farms. An 1845 United States apples nursery catalogue sold 350 of

5504-431: The most serious disease problems is a bacterial disease called fireblight , and three fungal diseases: Gymnosporangium rust, black spot , and bitter rot . Codling moths , and the apple maggots of fruit flies, cause serious damage to apple fruits, making them unsaleable. Young apple trees are also prone to mammal pests like mice and deer, which feed on the soft bark of the trees, especially in winter. The larvae of

5590-641: The name "Granny Smith's Seedling." The apple was so highly successful that the following year, many were exhibiting Granny Smith apples at horticultural shows. In 1895, the New South Wales Department of Agriculture recognised the cultivar and had begun growing the trees at the Government Experimental Station in Bathurst, New South Wales , recommending the gazette of its properties as a late-picking cooking apple for potential export. Over

5676-620: The name of an apple cultivar suggest that it originated as a seedling. Apples can also form bud sports (mutations on a single branch). Some bud sports turn out to be improved strains of the parent cultivar. Some differ sufficiently from the parent tree to be considered new cultivars. Apples have been acclimatized in Ecuador at very high altitudes, where they can often, with the needed factors, provide crops twice per year because of constant temperate conditions year-round. Apples are self-incompatible; they must cross-pollinate to develop fruit. During

5762-458: The necessity for storage. Controlled atmosphere facilities are used to keep apples fresh year-round. Controlled atmosphere facilities use high humidity, low oxygen, and controlled carbon dioxide levels to maintain fruit freshness. They were first researched at Cambridge University in the 1920s and first used in the United States in the 1950s. Many apples grow readily from seeds. However, apples must be propagated asexually to obtain cuttings with

Having "all the appearances of a cooking apple," they were not tart but instead were "sweet and crisp to eat." She took a stall at Sydney's George Street market, where the apples stored "exceptionally well and became popular" and "once a week sold her produce there." Smith died only a couple of years after her discovery (in 1870), but her work had been noticed by other local planters. Edward Gallard

5934-406: The nickname "Granny" Smith in her advanced years. The first description of the origin of the Granny Smith apple was not published until 1924. In that year, Farmer and Settler published the account of a local historian who had interviewed two men who had known Smith. One of those interviewed recalled that, in 1868, he (then twelve years old) and his father had been invited to Smith's farm to inspect

The true fruits or carpels are the harder interior chambers inside the apple's core. There are usually five carpels inside an apple, but there may be as few as three. Each of the chambers contains one or two seeds. The edible flesh is formed from the receptacle at

6192-476: The pears, apples, and quinces were combined into one genus that he named Pyrus and he named the apple as Pyrus malus . This was widely accepted, however the botanist Philip Miller published an alternate classification in The Gardeners Dictionary with the apple species separated from Pyrus in 1754. He did not clearly indicate that by Malus pumila he meant the domesticated apple. Nonetheless, it

Cape Town, Christchurch , Hobart , Punta Arenas and Ushuaia are officially acknowledged as the five international Antarctic gateway cities that serve as primary entry points for travel to the Antarctic region. Among the most developed nations in the Southern Hemisphere is Australia, with a nominal GDP per capita of US$ 63,487 and

6364-517: The resulting tree. Dwarf rootstocks can be used to produce very small trees (less than 3.0 m or 10 ft high at maturity), which bear fruit many years earlier in their life cycle than full size trees, and are easier to harvest. Dwarf rootstocks for apple trees can be traced as far back as 300 BCE, to the area of Persia and Asia Minor . Alexander the Great sent samples of dwarf apple trees to Aristotle 's Lyceum . Dwarf rootstocks became common by

6450-429: The same rootstock. Some cultivars, if left unpruned, grow very large—letting them bear more fruit, but making harvesting more difficult. Depending on tree density (number of trees planted per unit surface area), mature trees typically bear 40–200 kg (90–440 lb) of apples each year, though productivity can be close to zero in poor years. Apples are harvested using three-point ladders that are designed to fit amongst

6536-420: The speed of growth and the size of the resulting tree, allowing for easier harvesting. There are more than 7,500 cultivars of apples . Different cultivars are bred for various tastes and uses, including cooking , eating raw, and cider or apple juice production. Trees and fruit are prone to fungal , bacterial, and pest problems, which can be controlled by a number of organic and non-organic means. In 2010,

6622-476: The tilt of Earth's rotation relative to the Sun and the ecliptic plane , summer is from December to February (inclusive) and winter is from June to August (inclusive). September 22 or 23 is the vernal equinox and March 20 or 21 is the autumnal equinox. The South Pole is in the centre of the southern hemispherical region. Southern Hemisphere climates tend to be slightly milder than those at similar latitudes in

6708-577: The wild M. sieversii origin is only slightly smaller than the modern domesticated apple. At the Sammardenchia-Cueis site near Udine in Northeastern Italy, seeds from some form of apples have been found in material carbon dated to between 6570 and 5684 BCE. Genetic analysis has not yet been successfully used to determine whether such ancient apples were wild Malus sylvestris or Malus domesticus containing Malus sieversii ancestry. It

6794-529: The world) and 0.420 (number 187 in the world), respectively. The nominal GDPs per capita of these two countries do not go above US$ 650, a tiny fraction of the incomes enjoyed by Australians and New Zealanders. The Southern Hemisphere has long been secondary in the global distribution of demographic, economic and political power, as it has less land than the Northern Hemisphere. In recent times, however, countries such as Australia have made greater efforts to economically engage with those from their hemisphere. Before

6880-625: The year, at a time when Australian food exports were growing dramatically on the back of international demand. Granny Smiths were exported in enormous quantities after the First World War , and by 1975, 40 percent of Australia's apple crop was Granny Smith. By this time, it was being grown intensely elsewhere in the Southern Hemisphere , as well as in France and the United States . The advent of

6966-433: Was based on the diploid cultivar ' Golden Delicious '. However, this first whole genome sequence contained several errors, in part owing to the high degree of heterozygosity in diploid apples which, in combination with an ancient genome duplication, complicated the assembly. Recently, double- and trihaploid individuals have been sequenced, yielding whole genome sequences of higher quality. The first whole genome assembly

7052-451: Was certainly known then. Grafting is an essential part of modern domesticated apple production, to be able to propagate the best cultivars; it is unclear when apple tree grafting was invented. The Roman writer Pliny the Elder describes a method of storage for apples from his time in the 1st century. He says they should be placed in a room with good air circulation from a north facing window on

7138-469: Was estimated to contain around 57,000 genes, though the more recent genome sequences support estimates between 42,000 and 44,700 protein-coding genes. The availability of whole genome sequences has provided evidence that the wild ancestor of the cultivated apple most likely is Malus sieversii . Re-sequencing of multiple accessions has supported this, while also suggesting extensive introgression from Malus sylvestris following domestication. Central Asia

7224-533: Was one such planter, who extensively planted Granny Smith trees on his property and bought the Smith farm when Thomas died in 1876. Gallard was successful in marketing the apple locally, but it did not receive widespread attention until 1890. In that year, it was exhibited as "Smith's Seedling" at the Castle Hill Agricultural and Horticultural Show, and the following year it won the prize for cooking apples under

7310-639: Was used as such by many botanists. When Moritz Balthasar Borkhausen published his scientific description of the apple in 1803 it may have been a new combination of P. malus var. domestica , but this was not directly referenced by Borkhausen. The earliest use of var. domestica for the apple was by Georg Adolf Suckow in 1786. Apples are diploid , with two sets of chromosomes per cell (though triploid cultivars, with three sets, are not uncommon), have 17 chromosomes and an estimated genome size of approximately 650 Mb. Several whole genome sequences have been completed and made available. The first one in 2010

7396-725: Was voted down by the Committee for Vascular Plants of the IAPT in 2014, but in April 2017 the Committee decided, with a narrow majority, that the newly popular name should be conserved. The General Committee of the IAPT decided in June 2017 to approve this change, officially conserving M. domestica . Nevertheless, some works published after 2017 still use M. pumila as the correct name , under an alternate taxonomy. When first classified by Linnaeus in 1753,
