Abstract

ABSTRACT Selecting new sweet potato genotypes that are adapted to the soil, climate, and cultivation conditions of the producing regions is necessary. Thus, the objective of this work was to evaluate the agronomic performance of experimental genotypes of white-fleshed sweet potato in commercial fields, seeking to evaluate their potential as commercial cultivars. The experiments were carried out in the municipalities of Presidente Prudente, Emilianópolis, Tarabai, and Álvares Machado in São Paulo state. The randomized complete block design with five repetitions was used in the experiments, where the genotypes UZBD-L1-04 and UZBD-L5-29 were evaluated along with the controls Ligeirinha Paulista, Canadense, and INIA Arapey. The assessed traits were tuberous root total yield, number of commercial tuberous roots, commercial tuberous root yield, average mass of commercial tuberous roots, percentage of commercial tuberous root dry mass, soluble solids, resistance to pest-caused damage, root length, diameter, and appearance. UZBD-L1-04 performed better than the other genotypes (the average of environments for tuberous root total yield was 31.76 t/ha), showing great potential as a commercial cultivar for the studied region.
