Data from: Genotypic variation in lead (Pb) accumulation dataset in sweetpotato flesh for 10 accessions from the United States of America

The goal of this research is to reduce the lead content in sweetpotato through development of varieties that have concentrations below the action levels for lead in processed food intended for babies and young children in guidance for industry set forth by the Food and Drug Administration (FDA-2022-D-0278) in January 2025. This dataset provides the concentration of lead (ppb) accumulation in sweetpotato root tissue (flesh) for 10 genotypes that were grown in sand and treated with a nutrient solution containing 10 ppm of lead. For determination of lead concentration in the flesh, the skins were removed prior to elemental analyses with a single quadrupole inductively coupled plasma mass spectrometer (Agilent 7900 ICP-MS). All experiments were arranged in a randomized complete block design (RCBD) with three replications. This research demonstrates that genotype-specific variability of lead accumulation exists in U.S. sweetpotato germplasm and can be used for development of new varieties that have low levels of lead to ensure a safe source of food for human consumption.
