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

Summary 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.
