Abstract

Genetic maps of wheat chromosome 4A and rye chromosome arm 5RL, and the chromosomal locations of 70 sets of isozyme and molecular homoeoloci have been used to further define the structure of wheat chromosomes 4A, 5A and 7B, and rye chromosomes 4R, 5R and 7R. We provide evidence, for the first time, which is consistent with the presence of an interstitial segment on 4AL originating from 5AL, and of a segment originally from 5RL on 7RS. The evolutionary origins of the present chromosomes are discussed.
