| description | Arracacha has become an important part of social nutrition in the Andean region of South America with great cultural roots. However, the only regional variety cultivated in more than 90% of the country is called yellow common, a material planted for more than 30 years that has diminished its productive potential, leaving producers with no other alternatives. 94.6% of arracacha accessions preserved in the Colombian “Sistema de Bancos de Germoplasma de la Nación para la Alimentación y la Agricultura (SBGNAA)” was mainly collected in Colombian territory. Identification, evaluation and characterization of the preserved genetic resources allow identifying the selection variables desired for future breeding programs. 96 accessions were morphologically characterized during 2016; an important genetic diversity was seen using 11 quantitative and 30 qualitative traits. Using factorial analysis for mixed data (FAMD) and cluster analysis, six completely different groups were determined according to the plant vigor, which was influenced by plant height, plant diameter, petiole length and leaf length and width. Most important qualitative traits corresponded to flesh root color, leaf secondary pigmentation, petiole secondary color and flowering ability, being the most important selection factors. Flesh root color became a selection character due to in different communities of the Colombian Andean region roots color is an important element to differentiate plant materials. |

La arracacha se ha convertido en parte importante de la alimentación en la zona andina de Suramérica con gran arraigo cultural. Sin embargo, la única variedad regional cultivada en más del 90 % del país se denomina amarilla común, un material sembrado durante más de 30 años que ha disminuido su potencial productivo dejando a los productores sin otras alternativas. El 94.6 % de las accesiones de arracacha conservadas por el Sistema de Bancos de Germoplasma de la Nación para la Alimentación y la Agricultura (SBGNAA) de Colombia corresponden a colectas nacionales. La identificación y la evaluación del recurso genético permiten identificar los rasgos de selección deseados para futuros proyectos de mejoramiento. 96 accesiones fueron caracterizadas durante el 2016, se observó amplia variabilidad en 11 caracteres cuantitativos y 30 cualitativos. Mediante análisis factorial para datos mixtos (AFDM) y análisis de clúster, se determinaron seis grupos completamente diferenciados según el porte de la planta, el cual estuvo influenciado por las variables altura y diámetro de la planta, longitud del pecíolo, longitud y ancho de la hoja. Las variables cualitativas más importantes correspondieron a color de pulpa de la raíz reservante, pigmentación secundaria de hojas, color secundario del pecíolo y capacidad de florecimiento, convirtiendo estos atributos en factores de selección. El color de la pulpa de la raíz reservante se convirtió en un carácter de selección debido a que en muchas comunidades de la zona andina los materiales son fácilmente distinguibles por el color de la pulpa del nabo.
