The Solanum aethiopicum Gilo group, described as homogeneous, shows a high diversity, at least the morphological level. In Côte d’Ivoire, farmers distinguish three subgroups, named “N’Drowa”, “Klogbo” and “Gnangnan”, within this group. Data were obtained from 10 quantitative 14 qualitative morpho-agronomic traits measured in 326 accessions of eggplants, flowering fruiting stages. Univariate multivariate analyses allowed clearly clustering studied into subgroups. Fruit taste, leaf blade...

One way of boosting cocoa productivity which has plummeted over the last decade in Côte d’Ivoire is to introduce high performing clones. Preliminary observations have indicated that these new clones differing growth patterns and agronomic traits field. Assessing their compatibility paramount importance since will be made available farmers near future. This study was conducted Soubré, southwest d’Ivoire, evaluate ten (coded as C1, C8, C9, C14, C15, C16, C17, C18, C20, C21). A half diallel...

Indigenous leafy vegetables (ILVs) production is rapidly increasing in urban and peri-urban areas of Cote d'Ivoire. They are often consumed by the population. Nutritional composition samples selected ILVs collected farms markets Abidjan City were determined. Analysis included pH, total proteins, sugars, ascorbic acid (vitamin C), β-carotene (provitamin A), ash content, magnesium, iron, calcium, phosphorus, oxalic acid. The results revealed that all characterized tissues. Protein levels...

Manual crosses were carried out over two successive years on Dioscorea alata for the production of hybrid seeds between five females and seven males' parents with contrasting characteristics. A total 22951 flowers manually pollinated in both (14145 2016 8806 2017) 33 parental combinations. The ploidy levels determined by flow cytometry. crossed all diploids except female OA49 which was triploid. In fruiting seed rates comparable (25.06% 22.82%; 30.05% 30.18%). significant variation observed...
