Number of SNP markers for different genotype missing data thresholds and SNP calling strategies. Results for 124 genotypes of the Po Valley population (PV) and 154 genotypes of the Mediterranean population (Me) subjected to separate SNP calling (data sets PV_Sep and Me_Sep), or joint SNP calling with subsequent application of missing data thresholds to separate populations (PV_Joint and Me_Joint) or joint populations (COMMON)
