Journal Article 1997

Autor: Ortiz, R. Langie, H.

Plantains (Musa spp., AAB group) are an important food crop in the humid lowlands of sub-Saharan Africa. Understanding the relationships between growth characteristics and yield potential (t ha-1 yr-1) would be useful in developing an ideotype to guide breeding efforts for this crop. We investiga...

There is a genuine need within a plantain and banana (Musa spp.) breeding program to assess thoroughly the experimental materials through a sequence of trials. This will result in the selection of promising clones as potential new cultivars in the targeted agroecozone. Stability analyses and the ...

Plantain and banana (Musa spp.) are important staple food crops in the humid forest and mid-altitude agro-ecologies of sub-Saharan Africa. Black Sigatoka, caused by Mycosphaerella fijiensis, is an airborne fungal disease which attacks the leaves of the Musa plant. It is commonly considered the ma...

Current efforts to produce improved genotypes of plantain (Musa spp. AAB genomic group) and banana (Musa spp. AAA genomic group) depend on identifying triploid, female-fertile clones and crossing them with male-fertile, diploid wild or cultivated accessions. Apparent male fertility, as measured b...

Bananas (Musa spp. AAA group) are an important food and a source of income for farmers in tropical countries. Black sigatoka (Mycosphaerella fijiensis Morelet), a fungal leaf spot disease, is the major production constraint worldwide. The replacement of most of the susceptible banana landraces re...

Plantain hybrids and landraces, and banana cultivars (Musa spp. L.) were evaluated for three years in the plant and ratoon crops at three locations in the humid lowland forest (Mbalmayo and Onne) and derived savanna (Ibadan) agro-ecozones of sub-Saharan Africa. Additive main effects and multiplic...

Hybrids were obtained after in vitro germination of embryos from interploid crosses between triploid ‘French' plantain cultivars (Musa spp. AAB group). ‘Ntanga 2' and ‘Bobby Tannap' with diploid banana (Musa acuminata subsp. burmannicoides) ‘Calcutta 4'. Cross-pollinated bunches were harvested at...

Plantain and banana (Musa spp. L.) polyploid hybrids have been obtained after interspecific hybridisation and ploidy manipulations (i.e., interploidy crosses). The identification of promising hybrids for cultivar release requires their field testing to assess agronomic performance. The potential ...

L'hybridation et les manipulations ploodiques, c'est-a-dire les croisements interploidiques, ont permis d'obtenir les hybrides polyploides des plantains et des banaiers (Musa spp. L.). L'identification des hybrides prometteurs susceptibles de donner lieu aux cultivars necessite un essai au champ ...

Bananas and plantains (Musa spp.) are the most important tropical fruit crops. They form an integral component of the farming systems in the humid agroecological zones of the tropics. A broad array of applied cell and molecular techniques are increasingly being used worldwide to facilitate and en...
