Detection of the rescued plants derived from the dwarf male sterile wheat induced by maize pollens and control diploid plants by molecular market of DF-MR2 for Rht2 gene or Ms2 gene. M: Marker ladder; 1–11: The rescued haploid plants from DMSW. The plants numbered with 1, 2, 4, 5, 6, 8, 10 and 11 showed the Rht2-specific band, meaning they were the haploid type of Ms2. The plants numbered with 3, 7, and 9 didn’t have the Rht2-specific band, meaning they were the haploid type of ms2. 12: Chinese Spring, without the Rht2-specific band; 13: DS987, showing the Rht2-specific band.
