The sweet potato is an important food source in the world because, in addition to carbohydrates, it contains several vitamins, minerals, β-carotene and anthocyanins. The presence of self-incompatibility causes high genetic and phenotypic variation in the wild. This allows the formation of new accessions with advanced characteristics. This study aims to determine the productivity of sweet potatoes resulting from the cross between Antin 1 and Beta 2 accessions. The research was conducted using the experimental method in a completely randomized design with 4 repeats. The stem cuttings along 7 - 8 nodes of 10 plants from the cross of Antin 1 and Beta 2 accession (the plant code = C1 to C10) were planted in planter bags with a volume of 100 liters with media consisting of a mixture of soil: sand: manure = 3: 2 : 1. The tubers were harvested at the age of 4 months after planting, then the fresh weight of the tubers produced was measured. The data obtained were analyzed by Anova, followed by the Least Significant Difference test. The highest productivity was obtained in plants with code C6, which was 1394.6 ± 62.41 g/plant, that is equivalent to 46,486 tons/ha.
