As part of a participatory selection programme, promising individual trees were selected in 2004 in cocoa farms of southern and western Cameroon regions for yield and for low incidence of Phytophthora pod rot (Ppr) caused by Phytophthora megakarya. The aim of this study was to compare the levels ...

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), ...

The range of polymorphism of about 194 cocoa accessions collected in farms in Southern Cameroon during field surveys and 71 Trinitario and Upper Amazon clones available in genebanks on-station was assessed using 13 SSR markers. The gene diversity, genetic differentiation and genetic similarities ...

The original variation in the source population as well as the selection method may influence the genetic variation in further cycles of genetic improvement. Therefore, the objectives of this research were to determine genetic parameters (variance components and heritability) in source and interm...

Cowpea is the most important product in African dryland agriculture. Its protein-rich grains are the main product of the crop, which are commonly eaten in different forms by rural and urban peoples. African farmers growing cowpea in their fields often harvest low yields because many biotic and ab...
