Abstract: | A genetic map of the long arm of chromosome 6R of rye was constructed using eight homoeologous group-6 RFLP clones and five PCR markers derived from the rye-specific dispersed repetitive DNA family, R173. The map was developed using a novel test-cross F1 (TC-F1) population segregating for resistance to the cereal cyst nematode. Comparisons were made between the map generated with other rye and wheat group-6 chromosome maps by the inclusion of RFLP clones previously mapped in those species. Co-linearity was observed for common loci. This comparison confirmed a dramatic reduction in recombination for chromosome 6R in the TC-F1 population. The CreR locus was included in the linkage map via progeny testing of informative TC-F1 individuals. CreR mapped 3.7 cM distal from the RFLP locus, XksuF37. Comparative mapping should allow the identification of additional RFLP markers more closely linked to the CreR locus. |
