Abstract： A study was conducted on the fruit set rates of different sweet cherry varieties using self-pollination，cross-pollination，and backcrossing methods.The results showed that the fruit setrates of the two varieties，Rabins and Stanler， were high under all three polination methods.The fruit set rates for self-pollination were highest for Rabins and Stanler， reaching 36.6% and 32.8% ，respectively， while those for Meizhao and Xianfeng were low， at 5.5% and 6.3% ，respectively;When Brightwas used as the male parent in crosses with Meizhao and Pioneer， the fruit set rates were low， at 0% and 2% ， respectively. When Bright was used as the female parent in crosses with Zaodaguo， the fruit set rate was 9% .Thefruit setratefortheMeizhao × Qihao cross was 8% ，while thefruit setratesforother cross combinations were all above 13% .In termsof backcrossing， the fruit set rates for Meizhao and Samidouwereboth 13% ；Meizhao × Stanlerhadafruitsetrateof 21% ；Stanler × Samidouhadsimilar fruit set rates of 45% and 47% ; while most varieties had fruit set rates differingby approximately 20% in reciprocal crosses.Stanler， when used as both the male and female parent， had higher fruit set rates when crossed with other experimental varieties.
