Abstract: Three different genotypes (MsMs, Msms and msms) generated by selfing an individual after 8 generation by backcrossing the line 02-12 into a dominant male sterile line DGMS79-399-3 were rapidly screened using infrared fluorescence-labeled AFLP technology and Li-cor gene sequencer. In total, 17 AFLP markers were identified by screening 512 primer combinations. 11 markers covering 21 cM linked to the dominantmale sterility gene were found in 95 individuals of BC8 population, while the other 6 markers covering 9 cM were genetic carry-over without linkage to the gene. Three promisingmale sterile individualswere selected using the marker information, which had both less genetic drag and carry-over for further backcross.
