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...

This study examined the potential of somaclonal variation for the improvement of plantain. Approximately 500 somaclones each of ‘Agbagba’ (False Horn plantain) and ‘Bise Egome’ (French plantain) were field evaluated for their agronomic performance and response to the black Sigatoka disease. The m...

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...

De grandes differences existent entre les cultivars quant a la frequence et la nature des variations phenotypiques sur les plantes regenerees apres culture in vitro. Une grande part de ces variations mime la variabilite naturelle et les variants apparaissent essentiellement comme des copies d'aut...

Africa accounts for 50 of all plantain produced in the world. These plantains are overwhelmingly import as a food crop for local consumption. Black sigatoka has now invaded Africa, thereby endangering this important food source. The long term solution lies in the creation of black sigatoka resist...

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...
