The morphological and molecular diversity among fig accessions of 'Dottato', found in the PDO “Fichi di Cosenza” area was studied by evaluating 24 morphological traits and by genotyping with 18 microsatellite markers. The microsatellite allelic profiles among the putative clones of 'Dottato' indicated a moderate genetic variability, discriminating unambiguously most of the accessions. Only two groups of identity were found. The average expected and observed heterozygosity were 0.43 and 0.62, respectively. The mean polymorphic information content (PIC) was 0.4, varying from 0.08 (LMFC26) to 0.067 (FCUP 38_6). The morphological clustering allowed the distinction of all genotypes. Some genotypes evidenced better horticultural traits and quality characteristics.
