Data from: Phenotypic Variation in Leaf Morphology of the USDA-ARS Sweetpotato Germplasm Collection
For this study, 737 sweetpotato accessions were obtained from the USDA, ARS, PGRCU, Griffin, GA. Each PI was grown in the field in replicated plots at the U. S. Vegetable Laboratory, Charleston, SC. The mature leaves of each PI were evaluated for morphological characters.
Data from: Genetic Diversity and Population Structure of the USDA Sweetpotato (Ipomoea batatas) Germplasm Collections Using GBSpoly
Population structure and genetic diversity of 417 USDA sweetpotato (*Ipomoea batatas*) accessions originating from 8 broad geographical regions (Africa, Australia, Caribbean, Central America, Far East, North America, Pacific Islands, and South America) were determined using single nucleotide polymorphisms (SNPs) identified with a genotyping-by-sequencing (GBS) protocol, GBSpoly, optimized for highly heterozygous and polyploid species.
Data from: Color Analysis of Storage Roots from the USDA, ARS Sweetpotato Germplasm Collection
The periderm (skin) and stele (flesh) of sweet potato storage roots were measured using a Konica Minolta Chroma Meter, and data were recorded using the CIE 1976 L*a*b* and CIE L*C*h* color spaces. Data parameters presented are lightness (L*), red-green coordinate (a*), yellow-blue coordinate (b*), color intensity or chroma (C*), and hue angle (H*). Also included in this data set are percentage dry matter and root densities as these data are correlated to color values.
