Among the cereals, rye (Secale cereale L.) can be grown under extreme climatic and poor soil conditions and, is a major crop in North Europe. In the present paper, we report the development of a genetic linkage map of rye using a pooled F2 mapping population created from a reciprocal cross of two self-fertile inbred lines. The 183 mapped markers consist 139 RFLPs, 19 isozyme and protein markers, 13 microsatellites, 10 known function sequences and two morphological genes. The markers are randomly distributed on the seven chromosomes with a maximum of 38 on chromosome 5R and a minimum of 19 on chromosome 3R. In addition, 23 gene loci and 25 quantitative trait loci were aligned to chromosome regions. For some of the mapped or aligned genes comparable loci are present in other cereals. The homoeologous relationships of these loci are discussed. The potential of the new map for further genetic studies is outlined.
