Partial S-RNase genes of Ussurian pear were amplified and cloned by using two pairs of primers based on the conserved regions of pear S-RNase structure in nine cultivars of unknown S-genotypes.The PCR products were sequenced and compared in GenBank.The S-genotypes of the nine tested cultivars were identified as follows:'Hanxiang' was S36Sx,'Pingxiang' was S1S31,'Nanguoli' was S34S34,'Jinxiangshui' was S1Si,'Yanbian Daxiangshui' was S31S36,'Hanhong' was S27S34,'Xiaoxiangshui' was S29S34,'Huagaiwang' was S31S31S34S34,'Jinfeng' was S19S34.
