Abstract

Sweet potato [Ipomoea batatas (L.) Lam.] is a multipurpose plant due to the different uses for its roots, leaves, and branches. The objective of this study was to evaluate the ornamental potential of sweet potato accessions from the Germplasm Bank of Embrapa Hortaliças, Brasilia, DF, Brazil. The morphological characterization and evaluation of the ornamental potential used five accessions with distinct leaf shape (CNPH 980, CNPH 1205, CNPH 895, CNPH 796, CNPH 1284) and 12 qualitative and quantitative descriptors [plant type (PT), leaf lobe type (LLT), immature leaf color (ILC), leaf lobe number (LLN), branch color (BC), shape of central leaf lobe (SCLL), petiole pigmentation (PP), mature leaf size (MLS), mature leaf color (MLC), leaf shape (LS), branch yield (BY), and root yield (RY)]. In the evaluation of the ornamental potential, each criterion was scored from 10 (minimum) to 100 (maximum). Leaf lobe number was the trait that pleased the evaluators the most, and the greater the number of lobes, the greater was the ornamental potential. CNPH 980, CNPH 1205, and CNPH 1284 stood out for this trait. CNPH 1284 (almost divided leaf type) had the greatest score and was considered, by the evaluators, as the accession with the most harmonious aesthetics, indicating a great ornamental potential for the consumer market. All accessions studied presented considerable ornamental potential and could be used in floral arrangements or garden beds.
