摘要： The S-genotypes of 16 apricot (Prunus armeniaca L.) cultivars native to China were determined by the S-allele PCR approach and the results were confirmed by cross-pollination tests among these cultivars. Primer combination EM-PC2consFD + EM-PC3consR, based on the conserved regions C2 and C3 of Rosaceous S-RNase genes, was the most useful primer combination for identifying Chinese apricot S-alleles. Twelve S-RNase alleles were identified using this primer combination, and they were defined as follows: S-9 was 657 bp, S-10 was 266 bp, S-11 was 464 bp, S-12 was 360 bp, S-13 was 401 bp, S-14 was 492 bp, S-15 was 469 bp, S-16 was 481 bp, S-17 was 487 bp, S-18 was 1337 bp, S-19 was 546 bp and S-20 was 1934 bp. S-11-S-20 were new S-RNase genes deposited in GenBank under accession numbers DQ868316, DQ870628-DQ870634, EF133689 and EF160078, respectively. Our findings contribute to a more efficient breeding program of Chinese apricot and further studies on the S-RNase genes.
