[Note: This version supersedes version 1: https://doi.org/10.15482/USDA.ADC/1520889 Changes in version 2: A new Dataset was added - DataSet1-CardAlleles-iii.xlsx Datasets were renamed and renumbered in accordance to article revisions, and some changes made (see below for details): SupplementaryData1-Worldwide-genotypes-ii.xlsx => DataSet3-Worldwide-genotypes-ii.xlsx (Data with very minor changes, including the removal of three of 710 markers) SupplementaryData2-Lineages-FieldData-ii.xlsx => DataSet4-Lineages-FieldData-iv.xlsx (this file underwent minor revisions, with some extra comments added) SupplementaryData3-Fingerprints.tar => DataSet5-Fingerprints.tar (Data unchanged) SupplementaryData4-Austp183.xlsx => DataSet6-Austp183.xlsx (Data unchanged) SupplementaryData5-introgression.tar => DataSet2-WGSIntrogression.tar (A Dataset more stringently filtered with more control genotypes was used, cutting the number of markers from 2,566,180 to 2,337,866. More genotype output files were added, including controls. A genome-ordered list of A. cardenasii GKP 10017 diagnostic bases was added (Acard-diag_bases.txt.gzip).] Description This collection contains supplementary data for the manuscript "Legacy genetics of Arachis cardenasii in the peanut crop shows profound benefits of international seed exchange," which describes the impact of alleles from a wild relative of peanut, Arachis cardenasii, through analysis of those alleles across cultivars and breeding lines across many countries. The initial challenging cross, between tetraploid cultivated peanut (Arachis hypogaea) and the diploid species A. cardenasii, was carried out in the late 1960s. Subsequent work produce a tetraploid line that contained introgressed regions from A. cardenasii. Those chromosomal regions, several containing important resistance genes, were used in numerous breeding lines. The genetic legacy from A. cardenasii is documented in the files in this collection. The information includes genotyping data across peanut cultivars and breeding lines, generated through both genotyping arrays ("SNP chips") and whole-genome sequencing. Information in this collection also includes data related to impact of A. cardenasii on disease- and pest resistance in modern peanut varieties.
