Sweet potato (Ipomoea batatas L.) productivity in Brazil averages 14 t/ha, far below its potential. This low productivity is largely due to outdated genotypes and limited research on developing new ones. This study aimed to select white, orange, and purple-fleshed sweet potato genotypes based on agronomic performance during the autumn-winter season in the Great Florianopolis region, Santa Catarina. Forty-two genotypes from the UFSC breeding program and three commercial controls were evaluated. Various parameters were evaluated, including total root production, total number of roots, number of commercial roots, commercial root production, average mass of commercial roots, percentage of dry mass of commercial roots, insect damage, root appearance, root distribution in relation to the base, soluble solids, and skin thickness. The genotype UFSC-FP-09 showed higher values of soluble solids (12.4ºBrix). Genotypes UFSC-LW-76, UFSC-LW-102, UFSC-FC-04, UFSC-LO-03, UFSC-LP-109, and UFSC-LP-43 exhibited superiority in the analyzed productivity characteristics, thus being recommended for cultivation in the region.
