Abstract:

Apple (Malus domestica Borkh.) is a typical species in Rosaceae family that exhibits gametophytic self-incompatibility (GSI). In this paper, the research advance in the S-alleles (more than 30 S-genes) of apple was reviewed, PCR-based theoretical basis and methods for identifying the S-genotypes of apples were summarized, more than 500 S-genotypes of apples which were identified with various methods were enumerated, which would be valuable for selecting appropriate pollinated varieties and incompatibility parents for hybridization breeding.

Key words: apple, self-incompatibility, S-alleles, S-genetype
