^aCultivars and accessions of unknown SI/SC phenotype
^bIn general, fruit-setting percentages below 2–3% should not be undoubtedly associated to SC since some degree of pollen contamination cannot be fully discarded
^c S-genotyping of the progeny suggested some degree of non-self pollination and therefore SC could not be confirmed
^dNumber of individual plants obtained from the set fruits
