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.
