RFLP-based genetic map of rye (Secale cereale L.) chromosome 1R.

A map of chromosome 1R of rye was constructed using 16 molecular and biochemical loci. From long arm to short arm, known-function loci were placed in the order: XAdh - XLee - Glu-R1[Sec-3] - XPpdk-1R - XEm-1R-1 - XEm-1R-2 - Centromere - XNor-R1 -Gpi-R1 - XGli-R1 [Sec-1a] along with six anonymous genomic and cDNA clones from wheat. The map, which spans 106 cM with 12 loci clustered in a 15-cM region around the centromere, shows reasonably good agreement with previously published maps for the centromeric region, whereas the XNor-R1 - Gpi-R1 region gives a much larger distance than previously reported.
