Journal Article 1994

Autor: Ortiz, R. Vuylsteke, D.R.

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...

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...

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...

Forty-five Musa clones, including endemic and introduced cultivars plus hybrids, were evaluated for resistance against the banana weevil, Cosmopolites sordidus, in a field trial in Uganda. The predominant groups of staple crops, East African highland bananas (Musa spp. AAA) and plantains (Musaspp...

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...
