Although the number of normal pollen grainsper flower ranged from 5.75 × 10~4 in 'Choha' to 8.37 × 10~3 in 'Heiwa', the numbers did not show any clear differences according to ecological group of apricot. Abnormal pollen grains per flower ranging from 2.30×10 in 'Goldrich' to 2.70×10 in 'Goldcot' were frequently observed in all cultivars. The percentage of pollen germination was high in 'Goldcot', 'Royal', 'Tirynthos', 'World Peach' more than 10%, while low in 'NY 458' and 'Yamagata No. 3' less than 1%. Many cultivars excepting 'Choha', 'Early Orange', 'Hiroshimaoomi', 'Ivonne Liverani', 'Royal', and 'Tirynthos' showed low self-compatibility, less than 5% in the percentage of fruit set. Therefore, co-planting with pollinizer cultivars was recommended for the stable fruit set. Seven major orpromising cultivars under Korean climatic condition showed enough cross-compatibility with 9 cultivars, over than 20% as the percentage of fruit set. However, low percentage of fruit set in the combination 'Choha' x 'Chinese', 'Harcot' x 'Chinese' was observed and therefore the further evaluation will be required. 收起
