The orange-fleshed sweet potato has interesting nutritional characteristics, as it has a high concentration of beta-carotene, which is a precursor of vitamin A. Vitamin A deficiency is a public health problem and can be avoided by adequate intake of foods rich in beta-carotene, like the orange-fleshed sweet potato. The objective of this study was to evaluate the agronomic performance of orange-fleshed sweet potato experimental genotypes under the edaphoclimatic conditions of Western São Paulo. The experiment was carried out in the municipality of Alvares Machado-SP in a sweet potato production area on a commercial scale. Planting was carried out in October 2021 using a randomized block design with four replications. Five experimental genotypes of orange-fleshed sweet potato developed by CEOFOP were evaluated, namely: F-09, F-34, U2-05, U2-19 and C-14. The cultivar Beauregard was adopted as control. At 139 days after planting, the tuberous roots were harvested and the following evaluations were carried out: total tuberous root production in Kg ha-1; number of commercial tuberous roots in roots ha-1, production of commercial tuberous roots in Kg ha-1; average mass of commercial tuberous roots in g; dry mass percentage of commercial tuberous roots; length of roots in cm, diameter of roots in cm and soluble solids, in °Brix, appearance of roots using a scale of grades, and resistance to damage caused by insect pests. The yield of the evaluated genotypes was: F-09: 59,10 t ha-1, F-34: 105,96 ha-1, U2-05: 66,30 ha-1, U2-19: 66,02 ha-1, C-14: 87,54 ha-1, and Beauregard: 46,35 ha-1. The experimental genotypes present tuberous root quality similar to the commercial control 'Beauregard'. Genotypes F-34 and C-14 have flesh color similar to 'Beauregard', and genotype F-09 has dark orange flesh, a class above the control. All evaluated genotypes can potentially contribute to the increase in yield in Western São Paulo.
