Self-fruitfulness was investigated from 1993 to 2000 in 59 fruiting and 23 flowering cultivars of Japanese apricot, grown in Tsukuba, Ibaraki, Japan. In some cultivars, fruit set rate of artificial self-pollination was higher than that of natural self-pollination in the bag. Cultivars having more than 10% of fruit set rate were identified as self-fruitful. Consequently, 20 fruiting cultivars were identified as self-fruitful. The remaining cultivars (39 fruiting and 23 flowering) were self-unfruitful.
