Abstract:

    Musa formosana is a native wild banana in Taiwan. In order to document characteristic data, detailed characterizations of 140 clones of M. formosana which were collected from the whole Taiwan islands were described. M. formosana has stoloniferous sucker, red-purple streak in the lower epidermis blades and the vein at 7-10th leaf; basal nodes bear hermaphroditic flowers which yield fruits, the bracts of male buds are yellow-green blotch red-purple streak; the fruits are ageotropic with red-purple skin when mature, but turn deep-yellow after ripen. Seeds are black-brown and flattened to angular. On average, the pseodustem height is 1.9m, pseudostem circumference is 0.28m, ratio of leaf length and width is 3.29, petiole length is 0.31m; 5 hands per bunch, 9 fingers per hand, ratio of fruit length and circumference is 0.83, fruit pedicel length is 3.3cm, fruit weight is 24.56g, 100 seeds weight is 3.91g, and ratio of seed width and height is 1.9.

Key words:Musa formosana, Native species, Wild banana, Hermaphrodite
