PCA distribution in correlation with Md-PG1 _SSR 10kd. Numbers correspond to the varieties as reported in Table 1. Colours indicate the allelic dosage for Md-PG1_SSR10kd-3, with blue used for cultivars characterized by the absence of the “3” allele, green for cultivars having this allele in heterozygous state and red for cultivars carrying this allele in a homozygous state (thus present two times).
