Lablab purpureus (L) Sweet, also known as dolic bean is an unexploited pulse legume grown in tropical and subtropical regions of the world. Its productivity and agronomic characteristics can vary considerably depending on the agroecological conditions. This study was conducted with the aim of an agro morphological characterization of 12 lablab genotypes introduced into Burkina Faso from India. The trial was caarried out using an incomplete block design (Alpha latice), with three replications. Each replicate included 12 sub-blocks, each containing a genotype. Qualitative and quantitative data were collected and subjected to an analysis of variance, a Principal Component Analysis (PCA) and to a Hierarchical Ascending Classification (HAC) of genotypes using XLSTAT software. The results showed the existence of a genetic variability between the different genotypes for all the parameters (P < 0.05), except the type of bearing and the “stay green” character observed for all the genotypes at harvest. The seed color was black or brown. Agronomic performance varied from a genotype to another. The highest grain and fodder yields were registered from the genotype IC-0623096 (2222.33 kg ha-1 and 43777.66 kg ha-1), representing class 4, followed by HA-10-2 (1387 kg ha-1 and 29427.33 kg ha-1), and constituting class 3. Positive and strong correlations were observed between the number of days to 50% flowering and the the number of days to 95% maturity (r=0.794), plant height and harvest index (r=0.866) and the leaflet length and width (r=0.992). Stong and negative correlations were observed between the number of days to 50% flowering and plant height (r=-0.868) and the harvest index (r=-0.875), as well as between the leaflet length and harvest index (r=-0.74). These results could serve as a basis to better guide the selection and improvement work of lablab bean for a wide promotion of its cultivation in Burkina Faso
