| Abstract: | Eight mutant loci determining the traits waxy plant (w and wa1), brown culm (cb), multiple pistils (mp), weak plant with reduced plant height (np), monoculm growth habit (mc), compactum growth habit (ct3) and anthocyaninless (an) were mapped on rye chromosomes 4R (w, np), 6R (cb, mc) and 7R (mp, wa1, ct3, an). For five mutants (w, wa1, cb, mp, np) molecular and biochemical markers were applied, whereas for mc, ct3 and an a classical linkage analysis was performed. Furthermore, it could be demonstrated that homoeologous relationships exist between most of the mapped rye loci and comparable mutants in wheat and barley. It was confirmed not only that genes controlling fundamental aspects of plant biology are highly conserved across the Triticeae species but so also were many mutant loci.
