'Plant Breeding: Sustaining the Future' Abstracts of the XVIth EUCARPIA Congress, Edinburgh, Scotland, 10-14 September 2001 MOLECULAR GENE MAPPING IN RYE A. BÖRNER, V. KORZUN Institut fur Pflanzengenetik und Kulturpflanzenforschung, Gaterleben, Germany

We present a genetic linkage map of rye, developed from a reciprocal cross of two self fertile inbred lines. The map consists of 183 loci combining 139 RFLPs, 19 isozyme and protein markers, 13 microsatellites, 10 known function sequences and 2 morphological genes. In total the map spans 1063.4cM. The mapped loci formed seven linkage groups representing the seven rye chromosomes. In addition to the 183 precisely mapped markers 23 major genes and 25 QTL could be aligned to certain chromosome regions. The major gene loci were placed in the most probable positions of chromosomes 1R, 2R, 4R, 5R, 6R and 7R.
