| Research Abstract |
The combined use of doubled haploid (DH) lines and molecular markers in Alliumgenetic study can provide an essential information in Allium cepabreeding program. In this study, a gynogenic mapping population was successfully produced from F1plants between shallot and bulb onion DH lines, and could be used for constructing the linkage map of A. cepa. The successful research outcomes of this study were to map DNA markers linked to the Msnuclear fertility-restoring gene for S-type cytoplasmic male sterility and to determine the chromosomal locations of genes related to Fusarium basal rot resistance.
