Abstract

Crosses of plants from the same I0.1 line can be used for studying linkage relations between incompatibility loci and marker genes. Only one of the two incompatibility loci of rye has so far been localized, on chromosome 1R. In order to locate the second locus, crosses were performed with plants possessing known isozyme markers of the rye genome. Linkage was found with the β-glucosidase locus on chromosome 2R. By combined analysis a recombination value of C.144 was determined.
