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.
