The devastating threat of black leaf streak disease caused by Pseudocercospora fijiensis on plantain production in West Africa spurred the development of resistant hybrids. The goal of this research and development (R&D) undertaken was assessing the development and dissemination of two plantain h...

The relative contribution of ploidy status and genome composition to the variability of root traits in Musa was studied in 18 genotypes (from 5 genomic groups and 3 ploidy levels) at Onne, Nigeria. There was a significant effect of ploidy level on the different characteristics, except for root dr...

The cotton aphid (Aphis gossypii) is one of the major pests of okra. Eleven okra varieties collected from farmers’ fields in
Cameroon and four aphid-resistant accessions from The World Vegetable Center (AVRDC, Asian Vegetable Research and
Development Center) were evaluated from October 2012 to Ma...

Mycosphaerella species that cause the ‘Sigatoka disease complex’ account for significant yield losses in banana and plantain worldwide. Disease surveys were conducted in the humid forest (HF) and derived savanna (DS) agroecological zones from 2004 to 2006 to determine the distribution of the dise...

Dissemination of research results by the International Institute of Tropical Agriculture (IITA) had been a major challenge to the Institute as inappropriate dissemination mechanism was revealed as a major constraint to her earlier efforts in disseminating cooking banana technologies between 1990 ...

The triploid plantain landrace Obino l Ewai (Musa spp., AAB genome) has been crossed with a wild diploid banana (M. acuminata subsp. burmannica var. Calcutta 4 , AA genome) to generate full-sib diploid and tetraploid hybrids combining good agronomic performance and disease resistance. Microsatell...

Post-harvest characteristics of 36 Musa genotypes were evaluated under two cropping systems. Genotypes included AAA x AA, AAB x AA and ABB x AA (or BB) and their landraces AAA, AAB and ABB grown under monocropping and in the alleys of natural multi-species hedgerows. Significant differences (P &l...

Plantains and bananas (Musa spp. sect. eumusa) originated from intra- and interspecific hybridization between two wild diploid species, M. acuminata Colla. and M. balbisiana Colla., which contributed the A and B genomes, respectively. Polyploidy and hybridization have given rise to a number of di...

Thirty-six Musa genotypes, comprising the three major genomic groups (AAA, AAB, ABB) and their hybrids, were evaluated in four environments in Nigeria. Multiple correlation and path coefficient analysis was performed on phenological and yield traits. Bunch weight was more associated with phenolog...
