| description | Sesame seed is an important plant in the production of high-quality edible oil for its high nutritional and therapeutic value. The characterization of accessions is necessary for the identification of parents with characteristics of interest for obtaining new genetic materials. 160 accessions of sesame (Sesamum indicum L.) were characterized in the Nataima, municipality of El Espinal (Tolima), managed by the National Germplasm Banks System for Food and Agriculture, of which, 136 are from 25 countries; 81 descriptors were used, 30 quantitative and 51 qualitative. Factor analysis of mixed data was performed, and homogeneous groups were generated by cluster analysis for five groups of variables: plant and seedling, stem and root, leaf, seed and capsule and flower. 25 discriminating variables were selected from the previous structures and a new cluster analysis was performed. This generated five main groupings influenced by qualitative variables: habit, type of growth and height in plant and seedling; type of branching, pubescence and number of primary branches in stem and root; position, petiole length and leaf width; position of the capsule, color of the cover and number of capsules in seed and capsule and coloration of the corolla, extrafloral nectary and number of flowers per armpit in flower. The accessions TEHUANTEPEC SELEC, L-AJ-M-67, L-AJ-M-51, BROWN HAIR, CREOLE WHITE, NP-61, BACCHUS, INSTITUTE 104, RED CHINESE, R 198 and ACARIGUA present characteristics of interest that differentiate the formed groups. The discriminant variables and the identified materials allow the generation of varieties for future breeding programs in Colombia. |

El ajonjolí es una planta importante en la producción de aceite comestible de alta calidad por su gran valor nutricional y terapéutico. La caracterización de accesiones es necesaria para la identificación de parentales con características de interés para la obtención de nuevos materiales genéticos. Se caracterizaron 160 accesiones de ajonjolí en el Centro de Investigación Nataima, municipio de El Espinal (Tolima), manejadas por el Sistema de Bancos de Germoplasma de la Nación para la Alimentación y la Agricultura, de las cuales, 136 fueron colectadas en 25 países. La caracterización incluyó 81 descriptores: 30 cuantitativos y 51 cualitativos. Se examinaron factores para datos mixtos y se generaron grupos homogéneos mediante análisis de conglomerados para cinco grupos de variables: planta y plántula, tallo y raíz, hoja, semilla y cápsula y flor. Se seleccionaron 25 variables discriminantes de las estructuras anteriores y se realizó un nuevo análisis de conglomerados que generó cinco agrupaciones principales influenciadas por las variables cualitativas: tipo y hábito de crecimiento, color del tallo, forma de la hoja, tipo de ramificación, color interno de la corola, posición de las cápsulas y color de la semilla, y cuantitativas: altura, longitud de internudos, número de ramas principales y secundarias, número de cápsulas por nudo, número de cápsulas por planta, número de semillas por cápsula, peso de 1000 semillas y rendimiento. La estructura de la agrupación no presentó influencia por la procedencia de las accesiones. Las accesiones TEHUANTEPEC SELEC, L-AJ-M-67, L-AJ-M-51, PARDO PELUDO, BLANCO CRIOLLO, NP-61, BACO, INSTITUTO 104, CHINO ROJO, R 198 y ACARIGUA presentaron características de interés que diferencian los grupos formados. Las variables discriminantes y los materiales identificados permiten la generación de variedades para futuros programas de mejoramiento en Colombia.
