Progress in the breeding of plantain and banana has been restricted by the complex genetic structure and behaviour of cultivated polyploid Musa. Genetic improvement has been hindered due to the large amount of space required for growth and maintenance of plant populations, in addition to the long...

The major mycotoxins studied at the Consultative Group on International Agricultural Re-search (CGIAR) institutes are aflatoxins in maize, groundnut, sorghum and cassava, Fusa-rium toxins in maize, wheat and sorghum, and ochratoxin in cocoa and cashew. Genetic en-hancement (both through plant bre...

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...

Current efforts to produce improved genotypes of plantain and banana (Musa spp.) depend on crossing female-fertile clones with accessions that produce viable pollen. Musa accessions (168) were screened for production of viable pollen based on staining with acetocarmine glycerol jelly. Diploid hyb...

Seed set in triploid Musa spp. L. is very low due to high levels of sterility. This makes cross breeding of plantain and banana difficult. Nonetheless, several triploid plantain and banana cultivars produce seeds after hand pollination with diploid parents. This paper reports results about the pa...
