title: Genetic diversity of selected Iranian quinces using SSRs from apples and pears.
abstract: An Iranian National Quince collection containing 40 quince genotypes, originating from six distinct geographic areas, was screened using 15 SSR markers developed originally for apple and pear genomes. Overall, 13 markers exhibited polymorphism, with an average of 5.36 putative alleles per locus and a mean PIC value of 0.76. An UPGMA analysis divided the quince genotypes into five major clusters. The same results were obtained when the principal coordinates were plotted. The assignment test successfully allocated 83% of individuals into their place of origin. These results agree somewhat with the geographic origin of the quince accessions, and we conclude that geographic isolation leads to considerable genetic differentiation among Iranian quince collections. A significant ratio of transferability with a mean of 87.86% was measured, and we deduced that STMS markers derived from pear and apple have enough potential to detect polymorphism and differentiation in quince.
