Data from: Genotypic characterization of the U.S. peanut core collection

dataset
posted on 2024-02-15, 20:25 authored by Paul I. Otyama, Roshan Kulkarni, Kelly Chamberlin, Peggy Ozias-Akins, Ye Chu, Lori Lincoln, Gregory E. MacDonald, Noelle L. Anglin, Sudhansu Dash, David Bertioli, David Fernández-Baca, Michelle Graham, Steven B. Cannon, Ethalinda CannonEthalinda Cannon

This collection contains supplementary data for the manuscript "Genotypic characterization of the U.S. Peanut Core Collection", which describes genotyping results for the USDA peanut core collection. Each accession was genotyped with the Arachis_Axiom2 SNP array, yielding 14,430 high-quality, informative SNPs across the collection. Additionally, a subset of the core collection was replicated genotyped in replicate, using between two and five seeds per accession to assess heterogeneity within an accession. Supplementary files include: descriptive information about the genotyped accessions, SNP genotype calls in several formats, a phylogenetic tree calculated from the genotype data, Structure analysis, PCA analysis, and comparisons with the diploid progenitors.

This research was co-funded by the National Institute of Food and Agriculture and the National Peanut Board.
