Abstract: The results of studies on pollinated fruitfulness for apples showed that the self2fruit set percentage for a large number of cultivars , except ‘Megumi’, was low , which represented self-incompatibility. The fruit set percentage between combinations of few cross-pollinated cultivars was low which was mainly resulted from their same S2 genotype. Pollen germination rate behaved well except for triploid cultivars whose pollen failed to develop and
diploid cultivar ,‘Orin’.
