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 ...

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...

A multilocational evaluation trial comprising 18 Musa genotypes was carried out from 1991to1994 in three respective locations in Humid Forest (Onne, Nigeria and M' Balmayo, Cameroon) and the Forest- Savanna Transition (Ibadan, Nigeria) zones of West and Central Africa.

Ploidy polymorphism occurs in the hybrid offspring derived from interspecific crosses between triploid plantains (Musa spp. AAB group) and diploid bananas (M. acuminata). Therefore, Musa breeders are interested in the determination of ploidy and its effects on phenotypic expression of quantitativ...

Triploid plantains (Musa AAB) are among the most important horticultural crops of West Africa. However, all landraces are susceptible to black Sigatoka, a fungal disease caused by Mycosphaerella fijiensis, Morelet. To ameliorate the spread of this epidemic, exotic triploid cooking bananas (ABB), ...

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 ...

Banana has long been considered intractable to genetic improvement as only landraces are cultivated despite 75 years of breeding endeavors. However, recent advances in several breeding programs have demonstrated that development of improved germplasm through conventional cross-breeding may eventu...

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...
