Chloroplast microsatellite analysis of the five varieties under study for this family showed two different haplotype for the two parents: type “D” for Bombino bianco and type “A” for Uva rosa antica/Quagliano, respectively. All three siblings showed the type “D” chloroplast haplotype, thus Bombino bianco was the seed-bearer (female parent) and Uva rosa antica/Quagliano was the pollen donor (male parent) for all three of them.
