Resumo

The sweet potato crop presents good rusticity and productivity in unfavorable environments, making it a good option for family farmers, both for the food security it promotes and for its commercialization. In recent years the consumption of this tuberous root has increased, so that consumers are increasingly demanding. A more uniform and visually attractive appearance of the roots has been more demanded by national and international markets. The aim of this study was to evaluate qualitative parameters for tuberous roots of experimental genotypes of white-fleshed sweet potato, in order to identify a possible new commercial cultivar. The experiments were conducted in four municipalities in the western region of São Paulo, namely Presidente Prudente-SP (Location 1), Emilianópolis-SP (Location 2), Tarabai-SP (Location 3) and Álvares Machado-SP (Location 4). The experiments in sites 1 and 2 were installed in January 2021 (summer – autumn cycle); and from locations 3 and 4 in March 2021 (autumn – winter cycle). Experimental white flesh genotypes UZBD-L1-04 and UZBD-L5-29, which were pre-selected for productive, pest resistance, and physicochemical characteristics of roots, were evaluated in experiments conducted in 2019 and 2020 at the University of Oeste Paulista. As commercial controls, Ligeirinha, Canadense and INIA Arapey were used, and a block experimental design with randomized treatments in four replications was adopted. The characters evaluated were: average mass of commercial tuberous roots (MMRTC), in g; insect damage (DI) on a scale of 5 to 1, with 5 for damage free and 1 unacceptable for human and animal consumption; and soluble solids (SS) in °Brix; root diameter (DIAM) in cm; root appearance (APAR) through a scale of 1 to 5, with 1 being bad looking and 5 being good. Genotype-environment interaction occurred for the DI and SS parameters, while for the others there was only significance for genotypes. For the experimental genotype UZBD-L1-04, emphasis was observed for all the qualitative parameters evaluated, with local averages of 3.75 and 11.01 °Brix for DI and SS, respectively. Genotype means of 382.78 g; 7.31 cm and 4.38 for MMRTC, DIAM and APAR, respectively. In this way, the UZBD-L1-04 genotype proved to be superior to the controls. The experimental genotype UZDB-L5-29 did not show relevant results. The quality of sweet potato tuberous roots is linked to their acceptance by the consumer, in addition to being better remunerated to the producer. Therefore, the UZBD-L1-04 genotype reached the best qualitative results of the tested parameters, being able to be indicated as a new grow crops.
