Grand Nain bananas (also spelled Grande Naine) are banana cultivars of ''Musa acuminata''. It is one of the most commonly cultivated bananas and a source of commercial Cavendish bananas. It is also known as the Chiquita banana, because it is the main product of Chiquita Brands International. ==Taxonomy== Taxonomically speaking, the Grand Nain is a monocot and belongs to the genus ''Musa''. Species designations are difficult when considering bananas because nearly all banana cultivars are descendants and/or hybrids of the ''Musa acuminata'' or ''Musa balbisiana'', wild species that have been propagated for agricultural use. The Grand Nain is a cultivar of the well known Cavendish bananas. This group of bananas is distinguished from other groups by their AAA genotype. The AAA genotype refers to the fact that this group is a triploid variant of the species ''M. acuminata''. There are 33 chromosome present in the AAA cultivar and all produce seedless fruits through parthenocarpy.〔Randy C. Ploetz. ''Banana and plantain—an overview with emphasis on Pacific island cultivars''. Species Profiles for Pacific Island Agroforestry, Feb. 2007 ver. 1〕 This fact means that the plants are spread by conventional vegetative methods and lack sexual reproduction. This inability to genetically diversify makes Grand Naines as well as other AAA cultivars vulnerable to disease and pests.〔K.P. Martin et al. ''RAPD Analysis of a Variant of Banana (Musa Sp.) Cv. Grande Nain and its Propagation Via Shoot Tip Culture''. In Vitro Cell. Dev. Biol.—Plant,March–April 2006 42:188–192〕 The accepted name of Grand Nain is ''Musa acuminata'' (AAA Group) 'Grand Nain'. 'Grand Nain' or 'Grand Naine' literally translates from French meaning "Large Dwarf."〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Grand Nain」の詳細全文を読む スポンサード リンク
