This booklet offers an obtainable evaluation of the clinical ideas of banana creation and the way those relate to box practices. This re-creation has extended insurance of global exchange records and rules, breeding of recent cultivars with regards to affliction resistance and markets, customers for genetically-modified bananas and the expanding function of endophytes in controlling pests and illnesses.

Dessert types similar to ‘Pome’ (AAAB) – FHIA 01 or ‘Goldfinger’ (see above), FHIA 18 and SH 3640 (‘Prata Graúda’ in Brazil) or AABB types like FHIA 26. ● Cooking banana types similar to ‘Bluggoe’ (AAAB) – FHIA 03 (also good as a dessert type) and FHIA 25. ● Plantains types (AAAB) – FHIA 20 and FHIA 21. Taxonomic Classification, Cultivars and Breeding 35 ● Speciality bananas – These include bananas such as SH 4001, a plantain type with a high content of β-carotene. Despite their undoubted interest, and besides the above-mentioned case of ‘Goldfinger’ in Samoa, only Cuba (more than 11,000 ha of different FHIA hybrids, including FHIA 03, FHIA 18 and FHIA 23) and more recently Brazil (1134 ha in 2006), cultivate FHIA hybrids commercially (Aguilar Morán, 2006; Daniells, 2006).

1) Bracts lift but do not roll (Fig. 1) Broadly ovate, not tapering sharply (Fig. 1) Obtuse (Fig. 1) Distinctive brownish-purple outside; bright crimson inside Inside bract colour continuous to base Scarcely prominent (Fig. 1) Rarely corrugated Variably flushed with pink Cream, pale yellow or pale pink Taxonomic Classification, Cultivars and Breeding 23 By using 15 separate characters, each of which is diagnostic of differences between M. acuminata and M. 1). For each character in which a cultivar agreed completely with wild acuminata, a score of 1 was given, and for each character in which the cultivar agreed with balbisiana, a score of 5 was given.

The main difference between these two classifications is the introduction of almost pure balbisiana clones in the Thai grouping, which did not appear in the list of the original classification. Espino and Pimental (1990) used isozyme technology to segregate clones of pure acuminata, pure balbisiana and their hybrids, from one another. They found broad bands of malate dehydrogenase activity which were unique to pure balbisiana, and other bands which indicated an acuminata genome. They concluded that BB and BBB cultivars were unique and distinct from hybrid ABB clones.
