Abstract: To identify molecular markers tightly linked to the male sterility gene Ms in Chinese cabbage, a BC1 population was developed from the cross between male sterile plants(MsMs)and fertile double haploid line ‘FH-1’(msms). AFLP primers were screened for polymorphisms between the parents and two bulks representing fertile and sterile plants. Out of 512 primer combinations, 3 combinations gave polymorphic amplification patterns. These polymorphic amplicons were cloned and successfully converted to dominant SCAR markers, designated syau_scr02, syau_scr03 and syau_scr05. All the SCAR markers are located on one side of the Ms locus with a map distance ranging from 1.60 to 2.50 cM. These SCAR markers show high polymorphism between ‘AB01’ and 12 fertile inbred lines.
