However, in Colombia, this specie is underutilized, being cultivated in an artisanal way in the Caribbean region. The objective of this study was to evaluate the agronomic characteristics of sweet potato germplasm, under the agro-environmental conditions of the department of Valle del Cauca, Colombia. Twentynine genotypes were sown using a randomized complete block design and 27 genotypes, for use as parents in a single plot and evaluate the production of sexual seed for genetic recombination processes. A differential response was found between the evaluated genotypes, the genotype 1115-200_BOL exhibited the highest total and first category tuberous roots yield, 64.9 t ha-1 and 52.7 t ha-1, respectively: showing high percentage of first category tuberous roots (81 %). Genotypes 0615-070_COR, 1215-227_BOL and the Agrosavia Aurora variety showed abundant production of reproductive structures. In general, all these traits suggested that it is possible to establish sweet potato breeding processes as well as it insertion as alternative crop, under the agri-environmental conditions of the Valle del Cauca. In addition, the 1115-200_BOL and 1215-232_SUC genotypes were identified as possible commercial cultivars for this region of Colombia. La batata (Ipomoea batatas L.) es una especie de importancia económica, ya que contribuye a la seguridad alimentaria de millones de personas. Sin embargo, en Colombia esta especie es subutilizada, cultivándose de forma artesanal en la región Caribe. El objetivo de este estudio fue evaluar las características agronómicas de germoplasma de batata, bajo las condiciones agroambientales del departamento del Valle del Cauca, Colombia. Se sembraron 29 genotipos usando un diseño de bloques completos al azar y 27 genotipos, para su uso como parentales en una parcela única y evaluar la producción de semilla sexual para procesos de recombinación genética. Se encontró una respuesta diferencial entre los genotipos evaluados, sobresaliendo el genotipo 1115-200_BOL con un rendimiento de raíces tuberosas totales y de primera categoría de 64.9 t ha-1 y 52.7 t ha-1 respectivamente, y un porcentaje de raíces tuberosas de primera categoría del 81 %. En la producción de estructuras reproductivas, los genotipos que se destacaron fueron 0615-070_COR, 1215-227_BOL y la variedad Agrosavia Aurora. Todas estas características indicaron es posible establecer procesos de mejoramiento y la inserción de la batata como cultivo, bajo las condiciones agroambientales del Valle del Cauca. Además, se identificaron como posibles cultivares comerciales los genotipos 1115-200_BOL y 1215-232_SUC para esta región de Colombia.
