Data for: Variant filters using segregation information improve mapping of nectar-production genes in sunflower (Helianthus annuus L.)

Genotypic Data (VCFs):All VCF files contain imputed, biallelic SNPs derived from the same population but differ in the filtering strategies applied.Approach1_...vcf.gz: Filtered using hard thresholds (minQ ≥ 100, max Missing ≤ 0.75, MAF ≥ 0.05, inferred single copy).Approach2_...vcf.gz: Applies the same hard filters as Approach 1, with an additional Chi-Square filter (p-value ≤ 0.1).Approach3_...vcf.gz: Filtered using only a Chi-Square filter (p-value ≤ 0.1) on imputed, biallelic SNPs.Phenotypic Data (XLSX):nectar_phenotype.xlsx: Contains phenotypic measurements for the population, including individual identifiers (ID) and nectar volume data (nectar_mm_T, nectar_mm).
