Data from: Color Analysis of Storage Roots from the USDA, ARS Sweetpotato Germplasm Collection

<p>737 PI accessions from the US Department of Agriculture, Agricultural Research Service Sweetpotato Collection were grown in the field and in greenhouse pots, and storage roots were harvested. The periderm (skin) and stele (flesh) of storage roots were measured using a Konica Minolta Chroma Meter (CR 400, Konica Minolta, Inc., Tokyo, Japan), and data were recorded using the CIE 1976 L<em>a</em>b<em> and CIE L</em>C<em>h</em> color spaces. Data from this study is contained in a manuscript that will be submitted to Genetic Resources and Crop Evolution under the title "Color Analysis of Storage Roots from the USDA, ARS Sweetpotato Germplasm Collection." Data parameters presented are lightness (L<em>), red-green coordinate (a</em>), yellow-blue coordinate (b<em>), color intensity or chroma (C</em>), 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. </p><div><br>Resources in this dataset:</div><br><ul><li><p>Resource Title: Sweetpotato Periderm-Field.</p> <p>File Name: Sweetpotato-Periderm-Field.xlsx</p><p>Resource Description: Colorimeter data for the periderm of field-grown sweetpotato storage roots</p></li><br><li><p>Resource Title: Sweetpotato Periderm - Pots.</p> <p>File Name: Sweetpotato-Periderm-Pots.xlsx</p><p>Resource Description: Colorimeter data for the periderm of pot-grown sweetpotato storage roots</p></li><br><li><p>Resource Title: Sweetpotato Stele - Field.</p> <p>File Name: Sweetpotato-Stele-Field.xlsx</p><p>Resource Description: Colorimeter data for the stele of field-grown sweetpotato storage roots</p></li><br><li><p>Resource Title: Sweetpotato Stele - Pots.</p> <p>File Name: Sweetpotato-Stele-Pots.xlsx</p><p>Resource Description: Colorimeter data for the stele of pot-grown sweetpotato storage roots</p></li><br><li><p>Resource Title: Sweetpotato Dry Weights - Field.</p> <p>File Name: Sweetpotato-DryWt-Field.xlsx</p><p>Resource Description: Dry weight and root density data for the stele of field-grown sweetpotato storage roots</p></li><br><li><p>Resource Title: Sweetpotato Periderm - Summary Table.</p> <p>File Name: Sweetpotato-Periderm-Summary Table.xlsx</p><p>Resource Description: Colorimeter and dry weight summaries for the periderm of field-grown and pot-grown sweetpotato storage roots</p></li><br><li><p>Resource Title: Sweetpotato Stele - Summary Table.</p> <p>File Name: Sweetpotato-Stele-Summary Table.xlsx</p><p>Resource Description: Colorimeter and dry weight summaries for the stele of field-grown and pot-grown sweetpotato storage roots</p></li><br><li><p>Resource Title: Sweetpotato Stele - Summary Table.</p> <p>File Name: Sweetpotato-Stele-Summary Table.csv</p><p>Resource Description: CSV version of the data for Colorimeter and dry weight summaries for the stele of field-grown and pot-grown sweetpotato storage roots</p> <p></p></li><br><li><p>Resource Title: Sweetpotato Dry Weights - Field.</p> <p>File Name: Sweetpotato-DryWt-Field.csv</p><p>Resource Description: CSV version of Dry weight and root density data for the stele of field-grown sweetpotato storage roots</p> <p></p></li><br><li><p>Resource Title: Sweetpotato Stele - Field.</p> <p>File Name: Sweetpotato-Stele-Field.csv</p><p>Resource Description: CSV version of the Colorimeter data for the stele of field-grown sweetpotato storage roots</p> <p></p></li><br><li><p>Resource Title: Sweetpotato Periderm-Field.</p> <p>File Name: Sweetpotato-Periderm-Field.csv</p><p>Resource Description: CSV version of Colorimeter data for the periderm of field-grown sweetpotato storage roots</p> <p></p></li><br><li><p>Resource Title: Data Dictionary - Color Analysis of Storage Roots from the USDA, ARS Sweetpotato Germplasm Collection.</p> <p>File Name: sweetpotato_DD.csv</p></li><br><li><p>Resource Title: Sweetpotato Stele - Pots.</p> <p>File Name: Sweetpotato-Stele-Pots.csv</p><p>Resource Description: CSV version of Colorimeter data for the stele of pot-grown sweetpotato storage roots</p> <p></p></li><br><li><p>Resource Title: Sweetpotato Periderm - Pots.</p> <p>File Name: Sweetpotato-Periderm-Pots.csv</p><p>Resource Description: CSV version of Colorimeter data for the periderm of pot-grown sweetpotato storage roots</p> <p></p></li><br><li><p>Resource Title: Sweetpotato Periderm - Summary Table.</p> <p>File Name: Sweetpotato-Periderm-Summary Table.csv</p><p>Resource Description: CSV version of data for Colorimeter and dry weight summaries for the periderm of field-grown and pot-grown sweetpotato storage roots</p> <p></p></li></ul><p></p>
