Despite considerable efforts of Musa improvement programmes, banana and plantain production still depends upon a limited number of landraces selected by man from the natural germplasm. Inability to replace land-races by cultivars obtained through cross-breeding creates the increased risk of epide...
Secondary triploids were produced by crossing primary tetraploids with selected diploid partners and the parthenocarpic banana (Galeo). Comparisons between secondary tetraploids and secondary triploids showed that the secondary tetraploids generally had lower yields than secondary triploids. The ...

Leaf age effects on the leaf conductance to water vapour diffusion of the adaxial and abaxial leaf surfaces were measured in the morning and in the afternoon on 17 different plantain and banana (Musa spp.) genotypes. The irradiance levels increased three-fold while leaf to air vapour pressure def...

Bananas, Musa species, are perennial giant herbs belonging to the family Musaceae (Zingiberales: Scitaminae) (Simmonds, 1966; Tomlinson, 1969). Most bananas are cultivated for their fleshy fruits, but some clones are planted for their edible conns or for fiber. Bananas are among the most importan...

Bunch orientation is an economically important trait in plantain ( Musa spp. AAB group) and banana ( Musa spp. AAA or ABB groups). Pendulous bunches are more symmetrical than subhorizontal, horizontal, or erect bunches and are, therefore, better adapted for transportation. Erect, horizontal, subh...

Banana(Musa spp. L.) breeding, aiming to develop pest resistant cultivars for the export trade, started about 75 years ago in the West Indies. However, all banana exported today are still farmers' selection from somatic mutants of the group of Cavendish, and have a very narrow genetic base. In th...

Cultivated plantains and bananas (Musa spp.) are important staple crops in the humid forest and midaltitude ecologies of sub-Saharan Africa. Their water requirement is relatively high and they are very sensitive to dry soil conditions, which greatly limits their range of cultivation. While long-t...

A multilocational evaluation trial comprising 18 Musa genotypes was carried out from 1991to1994 in three respective locations in Humid Forest (Onne, Nigeria and M' Balmayo, Cameroon) and the Forest- Savanna Transition (Ibadan, Nigeria) zones of West and Central Africa.
