Abstract

The present study shows that the recently described mitochondrial H haplotype is associated with cytoplasmic male-sterility (CMS). This newsource of CMS appears to be different from the mitotype E-associated CMS most frequently found in natural populations. A mitotype H progenywith a sexual phenotype segregation was used to identify a gene restoring male fertility (R1H). Using bulk segregant analysis (BSA), nine RAPD markers linked to this restorer locus were detected and mapped. The comparison with other Beta genetic maps shows that the closest RAPD marker, distant from R1H by 5.2 cM, belongs to the same linkage group as the monogermy locus. In order to determine the position of R1H moreprecisely, four RFLP loci within this linkage group were mapped in the segregating progeny. It thus became possible to construct a linkage map of the region containing the RFLP, RAPD and R1H loci. The closest RFLP marker was located 1.7 cM away from R1H. However, a nuclear gene restoring the 'Owen' CMS which is currently used in sugar beet breeding is reportedly linked to the monogermy locus, raising the question ofa possible identity between the new CMS system and the 'Owen' CMS.
