Gametophytic incompatibility causes low productivity by preventing self- or cross-fertilization in apricot. In this research incompatibility was studied by field controlled pollination (complete di-allele pollination) and S-allele specific PCR genotyping of ‘Shahroodi’, ‘Nasiri’, ‘Jahangiri’ and ‘Noori’ apricots. Results revealed that all cultivars were self-incompatible but no cross-incompatibility was observed. Pollen type was significantly affected on fruit set percentage. ‘Noori’ had the highest fruit set as pollenizer on other cultivars. S-alleles genotypes indicated that ‘Shahroodi’ and ‘Jahangiri’ had a similar S-allele but it was different in ‘Noori’ and ‘Nasiri’. The results suggested that ‘Noori’ is the suitable pollenizer for three others.
