| Yhteenveto: | The sweet potato (Ipomoea batatas L.) is a species of economic importance, because it contributes to the food security of millions of people. 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. |
