'Williams' is a cultivar of the Giant Cavendish type in the Cavendish subgroup. It is one of the most widely grown cultivars in commercial plantations.
History, distribution and economic importance
'Williams' is believed to have first appeared as a tall mutant in a 'Chinese Cavendish' ('Dwarf Cavendish) plantation in Australia in 1910. It soon started replacing 'Chinese Cavendish' and, by the 1950s, became the most widely grown cultivar in the country.
It was introduced in Hawaii in 1953, where it soon replaced 'Chinese Cavendis'h in commercial plantations and also became the third most popular backyard banana (after 'Chinese Cavendish' and 'Hawaiian Apple').
The pseudostem of Williams has dark brown, black or red streaks.
The rachis is only partly instead of fully clothed, with a long naked section of rachis and a crowded cluster of leaf-like bracts right above the male bud and very small neutral flowers just below the fruit.
The colour of the bract internal face is yellowish. Male flowers are whitish with yellow tips.
Fruits are 15-23 cm long, slightly curved, and about 5 times as long as broad. Their apex is more bottlenecked than for other Cavendish clones, especially before full maturity. Like other Cavendish, they have a tuft of dead floral relicts at the tip.
