uropean bananas

In regions such as North America and Europe, Musa fruits offered for sale can be divided into "bananas" and "plantains", based on their intended use as food. Thus the banana producer and distributor Chiquita produces publicity material for the American market which says that "a plantain is not a banana". The stated differences are that plantains are more starchy and less sweet; they are eaten cooked rather than raw; they have thicker skin, which may be green, yellow or black; and they can be used at any stage of ripeness.[34] Linnaeus made the same distinction between plantains and bananas when first naming two "species" of Musa.[35]Members of the "plantain subgroup" of banana cultivars, most important as food in West Africa and Latin America, correspond to the Chiquita description, having long pointed fruit. They are described by Ploetz et al. as "true" plantains, distinct from other cooking bananas.[36] The cooking bananas of East Africa belong to a different group, the East African Highland bananas,[12] so would not qualify as "true" plantains on this definition.
Cavendish bananas are the most common dessert bananas sold
An alternative approach divides bananas into dessert bananas and cooking bananas, with plantains being one of the subgroups of cooking bananas.[37] Triploid cultivars derived solely from M. acuminata are examples of "dessert bananas", whereas triploid cultivars derived from the hybrid between M. acuminata and M. balbinosa (in particular the plantain subgroup of the AAB Group) are "plantains".[38][39] Small farmers in Colombia grow a much wider range of cultivars than large commercial plantations. A study of these cultivars showed that they could be placed into at least three groups based on their characteristics: dessert bananas, non-plantain cooking bananas, and plantains, although there were overlaps between dessert and cooking bananas.[40]
In Southeast Asia – the center of diversity for bananas, both wild and cultivated – the distinction between "bananas" and "plantains" does not work, according to Valmayor et al. Many bananas are used both raw and cooked. There are starchy cooking bananas which are smaller than those eaten raw. The range of colors, sizes and shapes is far wider than in those grown or sold in Africa, Europe or the Americas.[35] Southeast Asian languages do not make the distinction between "bananas" and "plantains" that is made in English (and Spanish). Thus both Cavendish cultivars, the classic yellow dessert bananas, and Saba cultivars, used mainly for cooking, are called pisang inMalaysia and Indonesiakluai in Thailand and chuoi in Vietnam.[41] Fe'i bananas, grown and eaten in the islands of the Pacific, are derived from entirely different wild species than traditional bananas and plantains. Most Fe'i bananas are cooked, but Karat bananas, which are short and squat with bright red skins, very different from the usual yellow dessert bananas, are eaten raw.[42]
In summary, in commerce in Europe and the Americas (although not in small-scale cultivation), it is possible to distinguish between "bananas", which are eaten raw, and "plantains", which are cooked. In other regions of the world, particularly India, Southeast Asia and the islands of the Pacific, there are many more kinds of banana and the two-fold distinction is not useful and not made in local languages. Plantains are one of many kinds of cooking bananas, which are not always distinct from dessert bananas.

Production theary

Statistics on the production and export of bananas and plantains are available from the Food and Agriculture Organization. Some countries produce statistics which distinguish between bananas and plantains, but two of the top three producers (India and China) do not, so comparisons can only be made using the total for bananas and plantains combined. The 2012 statistics (see Table 1) show that India led the world in banana production, producing around 18% of the worldwide crop of 139 million metric tonnes. Philippines was the next largest producer with around 7% of the worldwide crop. Its national data does distinguish between bananas and plantains, and shows that the latter made up over 95% of production. Ten countries produced around two thirds of the total world production.[Note 1]
The statistics for the export of bananas and plantains show a rather different picture (see Table 2). Total world exports at around 18 million metric tonnes amounted to only 12% of total world production; two thirds of the exports were generated by only five countries. The top three producing countries do not appear in this table, and two countries, Costa Rica and Guatemala, do not appear in the table of top producers. Only the Philippines has a consistent position in both tables. Exports were dominated by Ecuador, with 29% of the world total. Statistics for Ecuador distinguish between bananas and plantains; 93% of its exports were classified as bananas.[Note 1]
Bananas and plantains constitute a major staple food crop for millions of people in developing countries. In most tropical countries, green (unripe) bananas used for cooking represent the main cultivars. Bananas are cooked in ways that are similar to potatoes. Both can be friedboiledbaked, or chipped and have similar taste and texture when served. One banana provides about the same calories as one potato.[citation needed]
Most producers are small-scale farmers either for home consumption or local markets. Because bananas and plantains produce fruit year-round, they provide an extremely valuable food source during the hunger season(when the food from one annual/semi-annual harvest has been consumed, and the next is still to come). Bananas and plantains are therefore critical to global food security.
Bananas have been an important source of disagreement in the Doha Round of trade talks. A study for ICTSDshowed that the new deal on EU banana import tariffs will be a boon to Latin American exporters but would trigger a drop in exports of the fruit from African, Caribbean and Pacific (ACP) countries.[72]
Bananas are among the most widely consumed foods in the world. ChiquitaDel MonteDole, and Fyffes grow their own bananas in Ecuador, Colombia, Costa Rica, Guatemala, and Honduras. Banana plantations are capital intensive and demand significant expertise. The majority of independent growers are large and wealthy landowners in these countries. Producers have attempted to raise prices via marketing them as "fair trade" orRainforest Alliance-certified in some countries.[citation needed]
The banana has an extensive trade history starting with firms such as the Irish Fyffes and the US United Fruit Company (now Chiquita) at the end of the 19th century. For much of the 20th century, bananas and coffee dominated the export economies of Central America. In the 1930s, bananas and coffee made up as much as 75% of the region's exports. As late as 1960, the two crops accounted for 67% of the exports from the region. Though the two were grown in similar regions, they tended not to be distributed together. The United Fruit Company based its business almost entirely on the banana trade, because the coffee trade proved too difficult to control. The term "banana republic" has been applied to most countries in Central America, but from a strict economic perspective only Costa Rica, Honduras, and Panama had economies dominated by the banana trade.[citation needed]
The European Union has traditionally imported many of its bananas from former European Caribbean colonies, paying guaranteed prices above global market rates (see Lomé Convention). These arrangements have now been largely withdrawn under pressure from other major trading powers, principally the United States. The withdrawal of these indirect subsidies to Caribbean producers is expected to favour the more efficient banana producers of Central America, in which American companies have an economic interest. In addition, small-scale Caribbean producers are finding it difficult to comply with increasingly strict certification requirements. Some support is being provided to Caribbean countries under the EU's Banana Accompanying Measures (BAM).[73]
The United States produces few bananas. A mere 14,000 tonnes (14,000 long tons; 15,000 short tons) were grown in Hawaii in 2001.[74] Bananas were once grown in Florida[citation needed] and southern California.[75]
In March 2014 it was announced that Fyffes and Chiquita would merge to create the world's largest banana company, worth about $1bn (£597m). The new firm, named ChiquitaFyffes, is expected to sell about 160 million boxes of bananas annually.[76]

bananas reproduction

The genus Musa was created by Carl Linnaeus in 1753.[26] The name may be derived from Antonius Musa, physician to the Emperor Augustus, or Linnaeus may have adapted the Arabic word for banana, mauz.[27] Musa is in the family Musaceae. The APG III system assigns Musaceae to the order Zingiberales, part of the commelinid clade of the monocotyledonousflowering plants. Some 70 species of Musa were recognized by the World Checklist of Selected Plant Families as of January 2013;[26] several produce edible fruit, while others are cultivated as ornamentals.[28]
The classification of cultivated bananas has long been a problematic issue for taxonomists. Linnaeus originally placed bananas into two species based only on their uses as food: Musa sapientum for dessert bananas and Musa paradisiaca forplantains. Subsequently further species names were added. However, this approach proved inadequate to address the sheer number of cultivars existing in the primary center of diversity of the genus, Southeast Asia. Many of these cultivars were given names which proved to be synonyms.[29]
In a series of papers published from 1947 onwards, Ernest Cheesman showed that Linnaeus' Musa sapientum and Musa paradisiaca were actually cultivars and descendants of two wild seed-producing species, Musa acuminata and Musa balbisiana, both first described by Luigi Aloysius Colla.[30] He recommended the abolition of Linnaeus's species in favor of reclassifying bananas according to three morphologically distinct groups of cultivars – those primarily exhibiting the botanical characteristics of Musa balbisiana, those primarily exhibiting the botanical characteristics of Musa acuminata, and those with characteristics that are the combination of the two.[29] Researchers Norman Simmonds and Ken Shepherd proposed a genome-based nomenclature system in 1955. This system eliminated almost all the difficulties and inconsistencies of the earlier classification of bananas based on assigning scientific names to cultivated varieties. Despite this, the original names are still recognized by some authorities today, leading to confusion.[30][31]
The currently accepted scientific names for most groups of cultivated bananas are Musa acuminata Colla and Musa balbisiana Colla for the ancestral species, andMusa × paradisiaca L. for the hybrid M. acuminata × M. balbisiana.[32]
Synonyms of M. × paradisica include:
  • A large number of subspecific and varietial names of M. × paradisiaca, including M. p. subsp. sapientum (L.) Kuntze
  • Musa × dacca Horan.
  • Musa × sapidisiaca K.C.Jacob, nom. superfl.
  • Musa × sapientum L., and a large number of its varietal names, including M. × sapientum var. paradisiaca (L.) Baker, nom. illeg.
Generally, modern classifications of banana cultivars follow Simmonds and Shepherd's system. Cultivars are placed in groups based on the number of chromosomes they have and which species they are derived from. Thus the Latundan banana is placed in the AAB Group, showing that it is a triploid derived from both M. acuminata (A) and M. balbisiana (B). For a list of the cultivars classified under this system see List of banana cultivars.
