Abstract

Mutations in radish can be induced by exposure to ethyl methanesulfonate (EMS), and this method is suitable for obtaining target traits in new radish materials. We investigated the optimal concentration of EMS for mutagenesis on the radish variety Duan-Ye No. 13 (DY13). Treating DY13 radish seeds with 0.5% EMS led to the development of sterile mutants. During 3 years of continuous hybridization and tracing, male fertility remained stable at 100% sterility. Morphological observations showed that the anthers of these male sterile were wrinkled, curled, and browned; disintegration of the wall structure at the pollen tetrad stage caused eventual pollen abortion. Detection of the molecular marker ORF138-F/R confirmed that the target band could be amplified in this radish line; however, the band was not amplified in the corresponding maintainer line. Together, these results show that male sterile lines were successfully selected from DY13 radishes, demonstrating a new and effective method for breeding male sterile radish lines.
