摘要: Apple (Malus domestica Borkh), a member of the Rosaceae, shows gametophytic self-incompatibility (GSI) controlled by polymorphic S-alleles. Identifying the S-genotypes of apple cultivars can be applied on correct assignment of apple cultivars to cross-compatibility groups, which is important for the efficient production of apple fruit. This study characterized three new S-alleles (designated S_(44), S_(45), and S_(46)) in apple and developed an efficient analysis method that can be used to characterize S-genotypes by utilizing allele-specific polymerase chain reaction rapidly. Nineteen allele-specific primers were selectively designed to identify different alleles. Using this method, S-genotypes of 157 apple cultivars were identified.
