Contextualization: bean cultivation is considered an important component in cold climate farming systems because it offers multifunctional attributes [source of protein, rotation strategy, commercial option, etc.], which is why it is so common in the region of Nariño [Colombia].

Knowledge gap: knowledge about the biodiversity of this species must be expanded to facilitate a conservation strategy and the development of improvement programs.

Purpose: to characterize phenotypically and classify 73 broad bean accessions collected in Nariño.

Methodology: different bean seeds were collected in seven producer municipalities of Nariño. The accessions were planted in observation plots and evaluated using 19 quantitative descriptors. The results were analyzed using Pearson's correlation and Principal Component Analysis. In addition, a hierarchical grouping was carried out using Ward’s method.

Results and conclusions: phenotypic diversity was evidenced in the collection. In addition, different associations between descriptors that were related to the species' compensation dynamics were described. In reference to the multivariate analysis, four groups with characteristics were generated, and they can be explored for conservation purposes, detection of materials with superior characteristics, or genetic improvement of the broad bean crop.
