Solanum macrocarpon is an important leafy and fruit vegetable of Africa used in cooking. Its leaves and fruits are also a source of income for households. Despite of its nutritional an economic potential, this species is underdeveloped in Burkina. The objective of this study is to contribute to a best knowledge of Burkina Faso's accessions of Solanum macrocarpon using agro-morphological descriptors. This enable to identify outstanding accessions which could be involved in further breeding programs. A total of 32 accessions collected from different cultivation area were studied. The study showed great variability for most of the qualitative and quantitative characteristics studied. This important phenotypic variability observed and the high coefficient of determination (R2 > 0.4) could be the expression of a high genotypic heterogeneity of the studied accessions. Correlation analyses between morphological traits revealed positive and negative relationships, indicating predictable success for eventual breeding activities of Solanum macrocarpon. The hierarchical ascending classification (CAH) reveals a distribution of the 32 accessions in 4 groups independently of the collection zone. Among these groups, the group 1 accessions (RT13, RT17, LW14 and LW16) have an important leaf biomass and the group 4 accessions (PR1, BD4, BP7 and LS13) have more fruits, and could be used as potential donors for hybridization program to develop variety with higher yield potential.
