Genotyping with the 51,128 single nucleotide polymorphism (SNP) Illumina iSelect BeadArray resulted in 36,346 SNPs that were polymorphic between the eight parents (68.26%).
Four populations were used to study black seed coat and pod tip color: two biparental RIL populations, the UC-Riverside eight-parent MAGIC population, and a diversity minicore population.
Field-based assays for genetic mapping involved 92 F8 RILs derived from a cross of cowpea aphid-susceptible CB27 and aphid-resistant breeding line IT97K556-6.
215 F8 RILs developed from the cultivated (IT99K-573-1-1) and wild-type (TVNu-1158) accessions were used in mapping to study domestication-related traits.

87 RILs from CB27×24-125-B-1; 170 F2:3 families from IT84S-2049×UCR779; 132 F2:3 families from IT93K-503-1×UCR779 are used to study root-knot nematode (RKN) resistance.

Flanking SNP markers for First flower and Plant height QTLs discovered in a population of 175 F2:8 RILs derived from a cross between the Cowpeas GoldenEyeCream and IT98K-476-8. Marker positions determined by homology vs. the Vigna unguiculata IT97K-499-35 v1.0 assembly.
SNP mining from 183,118 ESTs sequenced from 17 cDNA libraries yielded ≈10,000 high-confidence SNPs from which an Illumina 1,536-SNP GoldenGate genotyping array was developed.
VCF file containing genotype information for 305 F8 RILs, 98.74% homozygous on average while diverse in agronomic traits, mapped to the cowpea IT97K-499-35.gnm1 genome.
