Radish, belonging to the family Brassicaceae, has a self-incompatibility which is controlled by multiple alleles on the S locus. To employ the self-incompatibility in an F1 breeding system, identification of S haplotypes is necessary. Since collection of S haplotypes and determination of nucleotide sequences of SLG, SRK, and SCR alleles in cultivated radish have been conducted by different groups independently, the same or similar sequences with different S haplotype names and different sequences with the same S haplotype names have been registered in public databases, resulting in confusion of S haplotype names for researchers and breeders. In the present study, we developed S homozygous lines from radish F1 hybrid cultivars in Japan and determined the nucleotide sequences of SCR, the S domain and the kinase domain of SRK, and the SLG of a large number of S haplotypes. Comparing these sequences with our previously published sequences, the haplotypes were ordered into 23 different S haplotypes. The sequences of the 23 S haplotypes were compared with S haplotype sequences registered by different groups, and we suggested a unification of these S haplotypes. Furthermore, dot-blot hybridization using SRK allele-specific probes was examined for developing a standard method for S haplotype identification.
