Abstract

The distribution of S-haplotypes and genetic relationships were evaluated for 47 accessions of 'Danji' radish (Raphanus sativus L. var. hortensis Baker f. gigantissimus Makino) originating from Jeju Island in South Korea. A total of 22 S-haplotype-specific SCAR markers for the S locus glycoprotein (SLG) and S receptor kinase (SRK) loci were tested, and six primer sets amplified locus-specific PCR fragments from at least one 'Danji' radish accession. S5 and S21 alleles atthe SLG locus were the most frequently distributed, and detected from 87.5% and 64.6% of the accessions, respectively. The frequency of the class-II haplotype at the SLG locus was 75%, more frequent than the class-I haplotype. The S23 allele at the SRK locus was detected from 7 accessions. Grouping of the accessions based on S-allele composition revealed three major groups, while 8 accessions showed a unique allelic composition. The genetic diversity of 47 'Danji' radishes and 1 'Gwandong' radish were also evaluated with 38 RAPD primers. A total of 312 bands were scored, and showed that 138 bands (44.2%) were monomorphic among the accessions, whereas 174 (55.8%) bands were polymorphic. Polymorphism rates ranged from 0.2 to 1.0, indicating significant variations in detecting polymorphism across RAPD primers. The genetic similarity coefficients among all pairs of the 48accessions varied from 0.62 to 0.93, and 42% of the comparisons exhibited values higher than 0.85. All the cultivars could be distinguished based on the DNA fingerprints revealed by RAPD. The comparisons between the dendrograms based on S-haplotypes and RAPDs indicate an unrelated and sporadic distribution for several accessions; however, there was a tendency for accessions with the same S-allelic composition to group into the same cluster.
