This research deals with intra- and interspecific DNA variation at five chloroplast microsatellite (Cp-SSR) loci in a large dataset of white oaks (Quercus, subgenus Quercus, sect. Quercus). Sampling was performed in 60 populations (180 individuals) over the Italian Peninsula, Sicily, and Sardinia. Details about taxonomy, geography of the investigated populations, and the used Cp-SSR markers are reported in the dataset files S1-3. Fragment size polymorphisms were identified as different length variants that were combined with GenAlEx 6.5 to define 28 total haplotypes.
