They include commercially important cultivars like 'Dwarf Cavendish' and 'Grand Nain'. Since the 1950s, these cultivars have been the most internationally traded bananas, replacing the Gros Michel banana (commonly known as 'Kampala banana' in Kenya and 'Bogoya' in Uganda), after crops of the latter were devastated by Panama disease.
History of cultivationEdit
Cavendish bananas were named after William Cavendish, 6th Duke of Devonshire. Though they were not the first known banana specimens in Europe, in around 1834 Cavendish received a shipment of bananas (from Mauritius) courtesy of the chaplain of Alton Towers (then the seat of the Earls of Shrewsbury). His head gardener and friend, Sir Joseph Paxton cultivated them in the greenhouses of Chatsworth House. The plants were botanically described by Paxton as Musa cavendishii, after the Duke. For his work Paxton won a medal at the 1835 Royal Horticultural Society show.
The Chatsworth bananas were shipped off to various places in the Pacific around the 1850s. It is believed that some of them may have ended up in the Canary Islands, though other authors believe that the bananas in the Canary Islands had been there since the fifteenth century and had been introduced through other means, namely by early Portuguese explorers who obtained them from West Africa and were later responsible for spreading them to the Caribbean. African bananas in turn were introduced from Southeast Asia into Madagascar by early Austronesian sailors. In 1888, bananas from the Canary Islands were imported into England by Thomas Fyffe. These bananas are now known to belong to the Dwarf Cavendish cultivar.
Cavendish bananas entered mass commercial production in 1903 but did not gain prominence until later when Panama disease attacked the dominant Gros Michel ("Big Mike") variety in the 1950s. Because they were successfully grown in the same soils as previously affected Gros Michel plants, many assumed the Cavendish cultivars were more resistant to Panama disease. Contrary to this notion, in mid-2008, reports from Sumatra and Malaysia suggested that Panama disease had started attacking Cavendish cultivars.
Taxonomy and nomenclatureEdit
Cavendish cultivars are distinguished by the height of the plant and features of the fruits, and different cultivars may be recognized as distinct by different authorities. The most important clones for fruit production include: 'Dwarf Cavendish', 'Grande Naine', 'Lacatan' (bungulan), 'Poyo', 'Valéry', and 'Williams' under one system of cultivar classification. Another classification includes: 'Double', 'Dwarf Cavendish', 'Extra Dwarf Cavendish', 'Grande Naine', 'Pisang Masak Hijau' (syn 'Lacatan'), and 'Giant Cavendish' as a group of several difficult to distinguish cultivars (including 'Poyo', 'Robusta', 'Valéry', & 'Williams'). 'Grande Naine' is the most important clone in international trade, while 'Dwarf Cavendish' is the most widely grown clone. 'Grande Naine' is also known as Chiquita banana.
Cavendish bananas accounted for 47% of global banana production between 1998 and 2000, and the vast majority of bananas entering international trade.
The fruits of the Cavendish bananas are eaten raw, used in baking, fruit salads, fruit compotes, and to complement foods. The outer skin is partially green when bananas are sold in food markets, and turns yellow when the fruit ripens. As it ripens the starch is converted to sugars turning the fruit from rancid to sweet. When it reaches its final stage (stage 7), brown/black "sugar spots" develop. When overripe, the skin turns black and the flesh becomes mushy.
Bananas ripen naturally or through an induced process. Once picked they can turn yellow on their own provided that they are fully mature by the time they are being harvested, or can be exposed to ethylene gas to induce ripening. Bananas which are turning yellow emit natural ethylene which is characterized by the emission of sweet scented Esters. Most retailers sell bananas in stages 3–6, with stage 5-7 being the most ideal for immediate consumption.The PLUs used for Cavendish bananas are 4011 (yellow) and 4186 (small yellow). Organic Cavendish bananas are assigned PLU 94011. Due to their phallic shape, they are sometimes used in sexual education classes to demonstrate the correct usage of a condom.
Bananas are parthenocarpic and reproduce through conventional vegetative reproduction rather than through sexual reproduction.Development of disease resistance depends on mutations occurring in the propagation units, and hence evolves more slowly than in seed propagated crops.The development of resistant varieties has therefore been the only alternative to protect the fruit trees from tropical and subtropical diseases like bacterial wilt and Fusarium wilt commonly known as 'panama disease'.
