| description | The Universidad de Nariño is home to a collection of bush pea plantlets that are a source of biodiversity for the genetic improvement of pea species in Colombia. The characterization of these accessions is required to identify genotypes with attributes that could be used in the search for new varieties. For the morphological characterization, 40 pea accessions were planted in Pasto, Colombia. 23 quantitative variables and 12 qualitative variables were documented, descriptors proposed for this species by the European Union in 2003. The data were subjected to Principal Component Analysis and Multiple Correspondence Analysis. Finally, a hierarchical classification method was applied using Ward’s method. The first four components, which explained 78.80% of the total variability of the population, were selected for the quantitative variables. Four groups were identified. Genotypes with the afila gene, which are of interest for pea breeding programs, were found in groups 1 and 2. The highest seed weight was in group 1, and the genotypes with the best reaction to powdery mildew were in group four. For the qualitative variables, the first six factors, which described 60.51% of the variability, were selected, and the hierarchical classification analysis resulted in five groups. The qualitative characteristics that contributed more to the differentiation of the groups included leaflet type, hilum color, degree of curvature of the pod, color and shape of the grain. |

La Universidad de Nariño cuenta con una colección de arvejas arbustivas que constituyen una fuente de biodiversidad para el mejoramiento genético de esta especie en Colombia. La caracterización de las accesiones es requerida para identificar genotipos con atributos que sean de interés para el proceso de obtención de nuevas variedades. Con el objeto de realizar la caracterización morfológica, 40 accesiones de arveja arbustiva fueron sembradas en Pasto- Colombia, para registrar 23 variables cuantitativas y 12 variables cualitativas que corresponden a los descriptores propuestos para esta especie por la Unión Europea en el 2003. Los datos obtenidos se sometieron a Análisis de Componentes Principales y Análisis de Correspondencias Múltiples. Finalmente, se aplicó el método de clasificación jerárquica utilizando el criterio de Ward. Para las variables cuantitativas se seleccionaron los cuatro primeros componentes que explicaron el 78,80% de la variabilidad total de la población. Se identificaron cuatro grupos. Los genotipos con el gen afila que son de interés para el mejoramiento de arveja se encontraron en los grupos 1 y 2. El mayor peso de semilla se encontró en el grupo 1 y los genotipos con mejor reacción al mildiú polvoroso en el grupo cuatro. Para las variables cualitativas se seleccionaron los primeros seis factores que describen el 60,51% de la variabilidad y el análisis de clasificación jerárquica resultó en la creación de cinco grupos. Las características cualitativas que más contribuyeron a la diferenciación de los grupos fueron tipo de folíolos, color del hilio, curvatura de la vaina, color y forma del grano.
