Abstract
A linkage map of rye (Secale cereale L.) is presented which comprises 60 loci including RFLPs, RAPDs, isozyme, morphological and physiologic al markers. The genetics and linkage relationships of these markers we re investigated in several inbred lines of rye. For the RFLP mapping a genomic library of PstI-digested DNA was constructed from which 50 si ze-selected clones were analysed. The portion of single-copy and multi -copy DNA and the frequency of polymorphic DNA was deter-mined. The ma rkers are unequally distributed over the seven chromosomes of rye. Man y of them exhibit a distorted segregation. The main region of deviatin g segregation ratios could be localized near the self-incompatibility loci.
