Abstract Three previously described highly polymorphic SSR (microsatellite) primer pairs were tested on 126 sweet cherry ( Prunus avium L.) accessions to adapt a fast, reliable method for preliminary screening of sweet cherry germplasm collections and to compare two sweet cherry germplasm collections: at the Latvia State Institute of Fruit-Growing, Dobele (LIFG-Dobele) and at the Division of Horticultural Genetics and Plant Breeding at Balsgard, Department of Crop Sciences, Swedish University of Agricultural Sciences (SLU-Balsgard). The SSR loci were highly polymorphic with 4–10 different alleles and 5–18 genotypes. Heterozygosity values ranged from 0.431 to 0.809, gene diversity (PIC) valu…
