Description
Summary:Genetic diversity of the Greek plum germplasm collection was investigated using a combined RAPD and ISSR molecular markers approach. Twenty-six genotypes held at NAGREF-Naoussa were analyzed, producing in total 150 loci, of which 116 were polymorphic. Both techniques were highly informative and had a discrimination power greater than 0.9. RAPD and ISSR dendrograms were fairly correlated. The accessions were clustered according to ploidy and species. All <i>Prunus domestica</i> genotypes were grouped together and showed greater similarity to <i>P. insititia</i> and <i>P. cerasifera</i> genotypes compared to P. salicina, which was found genetically diverged. Bayesian structural analysis revealed significant admixture among genotypes. Greek varieties <i>P. domestica</i> ‘Goulina’ and ‘Asvestochoriou’ exhibited a distinctive genetic background, differentiating them from foreign varieties. This feature could make them attractive for breeding programs, since they can increase genetic diversity.
