Our study aimed to characterize morpho-agronomically, the sweet potato germplasm. This experiment was carried out at the experimental farm of the “Participatory Rural Development Foundation (PRDF)” located at 59 Canal Road, Shivpur-Shahbazganj, Gorakhpur, Uttar Pradesh, India. At the experimental farm, evaluations were done for the soil properties, and morpho-agronomic traits of the aboveground part of the sweet potato germplasm. Results of the soil analyses exhibited low soil fertility at the study site. Among the sweet potato accessions, greater variability were observed forvine internode length (2.0–6.0 cm), internode diameter (1.5–3.0 cm), leaf lobe type (deep to very light teeth), the number of lobes per leaf (1–6 lobed), the height of the central lobe (9.0–17.5 cm), mature leaf size (93.5–332.0 cm), and general leaf shape (lobed to triangular). Based on our findings, the sweet potato being cultivated at the PRDF experimental farm exhibited high phenotypic variability in morpho-agronomic traits, and the morphological characterization was highly efficient in detecting genetic variability among the accessions. Therefore, our study suggests thatthe PRDF experimental farm is capable for conserving sweet potato genotypes with expressive genetic diversity, and this crop shows a good prospect for the breeding program.
