Abstract
A genetic linkage map of rye composed of 91 loci (88 RFLP, two morphological and one isozyme markers) has been developed using two reciprocal crosses. The RFLP loci covering all seven chromosomes were detected by a selection of rye, wheat, barley and oat cDNA and genomic DNA probes. The level of polymorphism was dependent on the source of the clones, with a ranking of rye>wheat>barley>oat. Distorted segregations were detected in linkage groups of chromosomes 1R, 4R, 5R and 7R. When the recombination of the two reciprocal crosses was compared, no systematic increase or decrease in one or the other direction was observed suggesting that a combination of populations of reciprocal crosses is possible.
