%X Eighteen cape gooseberry introductions from the collection of Nari o's University were characterized through morphological and molecular RAM markers. For the morphological characterization were used 10 plants of each entry. Through the principal component analysis (PCA) was found that 81.75 % of the total variability of the study population, regarding quantitative variables, is represented by three main components, defined by characteristics related to fruit and seed. The qualitative multiple correspondence analysis (MCA) indicated that 61,51% of the total variability was explained by five factors, defined mainly by traits related to the flower and calyx. The classification analysis (CA) based on morphological characterization, grouped introductions by total soluble solids and length of calyx. In the molecular characterization 66 polymorphic loci were found with bands of 500 to 3,000 bp. The value of heterozygosity for the 18 introductions was 0.44. Based on the Nei genetic distance criterion, it was found the less genetic distance (0.095) between A-34 and Sylvania, the largest genetic distance (1.42) occurred between Ecotype Colombia and Peru. Clusters of morphological and molecular characterization are mismatched, probably because phenotypical and genotypical characteristics, studied are governed by different factors. Fueron caracterizadas morfol車gica y molecularmente con marcadores RAM, 18 introducciones de uchuva de la colecci車n de la Universidad de Nari o. Para la caracterizaci車n morfol車gica se sembraron 10 plantas de cada introducci車n. A trav谷s del an芍lisis de componentes principales (ACP) se determin車 que el 81,75% de la variabilidad total de la poblaci車n estudiada, respecto a las variables cuantitativas, est芍 representada por tres componentes principales, definidos por caracter赤sticas relacionadas con el fruto y la semilla. En cuanto a las cualitativas, el an芍lisis de correspondencias m迆ltiples (ACM) indica que el 61,51% de la variabilidad total, est芍 explicada por cinco factores, definidos principalmente por variables relacionadas con la flor y el c芍liz. El an芍lisis de clasificaci車n (AC) con base en la caracterizaci車n morfol車gica, agrup車 las introducciones por s車lidos solubles totales y longitud del c芍liz. En la caracterizaci車n molecular se encontraron 66 loc赤 polim車rficos con bandas de 500 a 3.000 pb. El valor de heterocigosidad para las 18 introducciones fue de 0,44. Con base en el criterio de distancia gen谷tica de Nei, se encontr車 la menor distancia gen谷tica (0,095) entre UN-34 y Silvania, la mayor distancia gen谷tica (1,42) se dio entre el e
