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...

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...

Four types of morphologically distinct somaclonal variants were identified in a population of False Horn plantain (Musa spp., AAB group) plants produced by in vitro shoot-tip culture. Field performance of these variants was compared with true-to-type plantain to evaluate their horticultural trait...

Plantain and banana (Musa spp.) are integral components of the farming systems in the humid forest and mid-altitude ecologies of sub-saharan Africa. They provide more than 25% of the carbohydrates for approximately 70 million people in the region. Major constraints to plantain and banana producti...

The susceptibility and sensitivity to Radopholus similis and Helicotylenchus multicintus of 2-month-old plants derived from sword suckers (early screening) and of sword suckers of established 18-month-old mats belonging to 12 Musa genotype was investigated and compared. Differences in nematode po...
