Knowledge of the self-(in)compatibility trait in commercial apricot cultivars is of great importance for breeders and growers. Five commercial apricot cultivars, widely grown in Iran, were self- and cross-pollinated to determine their pollen and stylar compatibility. Fruit-set in the orchard and pollen tube growth in pistils, from flowers pollinated in the laboratory, were evaluated. In addition, specific primers previously designed to amplify fragments of the S alleles responsible for the incompatibility trait, were used to amplify DNA extracted from the five cultivars. All results agreed and confirmed that three out of the five cultivars studied were self-incompatible, two of which were cross-incompatible and therefore had the same genotype. The cultivars, 'Ghorban-e-Marageh' and 'Ghermez-e-Shahroodi' were self-compatible and, interestingly, shared a PCR band with all Spanish self-compatible apricot cultivars examined to date.
