Cleome gynandra L., known as kenebdo in Burkina Faso is an important traditional leafy vegetable for nutritional supplement meant to populations in Burkina Faso where many people, especially children, are suffering from chronic malnutrition. Indeed, due to its high nutritional value, it is a good food supplement in providing nutritional and medicinal needs. This study aims at identifying varieties of interest according to climatic zones of Burkina Faso for varietal improvement of species through multi-local evaluations of a collection of C. gynandra. 36 accessions were basically collected in 12 provinces of Burkina Faso and used as plant material. Experiments were conducted in three sites located in the three climatic zones of Burkina Faso. They were conducted during rainy season using a Fischer block design with three replications. Measurements and observations were made on 16 variables, such as 4 qualitative and 12 quantitative variables. The study revealed great agromorphological variability within the accessions with significant different performances according to the three climatic zones. It also showed significant interaction between accessions and experimental sites for most of the variables. In general, the best agronomic performances were observed in Bobo Dioulasso followed by Ouagadougou while the low performances were recorded in Dori. For each climatic zone, a set of 10 accessions were identified as genotypes of interest that could be used for varietal improvement of C. gynandra in Burkina Faso.

Forty-one (41) accessions of the jute potager (Corchorus olitorius L.) collected in Burkina Faso were evaluated on July 2014 with twenty-five (25) characters according to a Latinized Apha-Plan. The global objective of this study is to contribute to a better knowledge of the agromorphological diversity of C olitorus of Burkina Faso. The study revealed that 75,61% of the accessions studied belong to C olitorius var olitoriu L. variety and 24,39% belong to C olitorius var incisifolius Asch.& Schw variety. It showed indeed that several characters discriminate the accessions at 1%. The study of the structuring of diversity revealed three groups of accessions on the basis of the plant height, stem diameter, width of leaf and leafy biomass. Thus, the group I is constituted of big size accessions with robust stem, high leafy biomass and thin fruits. The Group II is constituted of individuals with performances relatively low. The Group III is a mixed group constituted with 65% C olitorius var clitoris L. and 35% of C olitorius var incisifolius Asch. & Schw. This group is made up of individuals with reduced size, with weak leafy and big fruits.
