We constructed a genetic map of R.sativus using an F2 mapping population derived by crossing the inbred lines 835 (susceptible) and B2 (resistant).A total of 220 markers distributed in 9 linkage groups (LGs) were mapped in the Raphanus genome,covering a distance of 1041.5 cM with an average distance between adjacent markers of 4.7 cM.Of the 220 markers mapped in present study,BLASTN was used to check for genes homologous to those in the A.thaliana genome;total 139 loci which consist of 21 conserved syntenic regions corresponding in the A.thaliana genome were identified.
