摘要： Sweet cherry cultivars display a self-incompatibility system that restricts self-fertilization and fertilization between cultivars bearing identical S-alleles. PCR-based S-allele typing system for sweet cherry cultivars has been recently developed. It has been reported that all known self-incompatibility ( S) alleles of sweet cherry were more than 16 based on the AS-PCR analysis. In this work, two sets of AS-PCR primers that were designed based on conserved domains of cDNA sequences of S-RNases has been used to characterize the S-genotype of 38 sweet cherry cultivars, including 15 cultivars whose S-genotype had not been previously described. Pollination test was also performed to validate the PCR results, and the consistent results were got. A wide variation in the frequency of S-alleles in the Sweet cherry germplasm was observed. S(3) was the most common in the cultivars evaluated, and S(7), S(10)-S(16), S(23)-S(25) as rare allele was not found in China geographical areas in our study.
