Jointly genotyped and audited VCF for the WF9C and V158C maize backcross families

This dataset contains a jointly genotyped and genotype-audited VCF for 39 maize samples representing recurrent-parent replicates and successive generations of the WF9C and V158C backcross families. The dataset comprises 376,230 sorted biallelic SNPs across the ten chromosomes of the Zea mays B73 NAM version 5.0 reference assembly. Genotype-level annotations include allele depth, read depth, genotype quality, strict and relaxed quality-control flags, and recurrent- and non-recurrent-allele read counts. The audit VCF retains the original genotype calls together with QC annotations; genotypes failing the specified filters are therefore not necessarily replaced with missing values. The accompanying Tabix index enables random genomic access. Detailed field definitions and filtering thresholds are provided in the README file.
