Abstract: Armeniaca vulgaris Luntaibaixing and other twenty six Xinjiang apricot cultivars were selected for positive and negative cross to study the effect of different pollen sources on fruit setting and fruit quality. The results showed that different cultivars pollinating had improved the fruit setting rate of Luntaibaixing，especially by Kabakehuanna， Yiliakeyulvke， Teerwanyulvke，but in negative cross experiments，only eight cultivars fruit set percentage had been increased after pollinated by Luntaibaixing，such as Kuchebaixing，and the others were lower than natural pollination; compared with spontaneously pollinated fruit，the single fruit weight，stone weight，fruit shape index，soluble solids content，Vc content，titratable acid content and total sugar content of Luntaibaixing were all affected by pollination cultivars，among them，Vc content of crossbreeding fruit were decreased significantly which pollinated by Zaoshuhuanna， Akedalazi， Akeayi（P＜0.01），titratable acid content significantly were enhanced which pollinated by Akeayi， Jiagedamayisang，and Milu，etc （P＜0.01）；while pollination varieties had less influence on fruit shape index，there were only Kuchebaixing and Kalahuanna had significantly effect on it（P＜0.01），and fruit shape index of five varieties like as Daguohuanna were significantly decreased （P＜0.05）；comprehensively considered with fruit setting rate， Kabakehuanna， Zaoshuhuanna， Yiliakeyulvke were suitable for Luntaibaixing as pollination trees. There were obvious differences in fruit setting and fruit quality of Luntaibaixing which pollinated by different cultivars，so fruit setting rate and fruit quality could be improved according to requirement by selecting male parent in production.［Ch，5 tab. 10 ref.］
