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...

IITA has increased its knowledge about major constraints across agro-ecological zones and gene pools for Musa production in Africa. The authors review the following different aspects: adding more desirable attributes to breeding populations; integration of host-plant resistance, enhanced utilizat...

Proper classification and establishment of relationships between and within Musa taxonomic clusters will be important tools for the genetic improvement of plantain and banana. This paper assesses the value of a phenotypic diversity index, based on 16 quantitative descriptors, for germplasm cluste...

Drought tolerance combined with resistance to black sigatoka (BS) disease are two desirable traits for plantains in some parts of the tropics. Field evaluation of leaf stomatal conductance, single leaf transpiration rate, photochemical efficiency, and role of stomata in BS resistance, was done fo...

In vitro-propagated plants of plantain (Musa spp., AAB group) did not manifest consistently superior horticultural performance compared to conventional propagules. Tissue culture plants grew vigorously and taller than sucker-propagated plants, but higher yield was not obtained, probably because o...

Bananas and plantains (Musa spp. L.) are important staple food crops in tropical countries. A major constraint to their sustainable production is black sigatoka leaf spot disease, caused by the fungus Mycosphaerella fijiensis Morelet. Resistance breeding is the most appropriate intervention to co...

Plantain and banana (Musa spp. AAB and AAA groups) are perennial giant herbs of the tropics which develop parthenocarpic fruits. At least three independent but complementary dominant genes control vegetative parthenocarpy in Musa. One of these genes, P1 segregates in euploid hybrid progenies deri...
