Monosomic and disomic substitutions of Imperial rye chromosome C for 4A of Chinese Spring wheat were analysed for two enzyme markers, alcohol dehydrogenase (ADH) and 6-phosphogluconate dehydrogenase (6-PGD). The gene(s) coding for ADH and 6-PGD were located on the short and long arms of rye chromosome C respectively.

Isozyme analyses revealed that the substitute chromosome was a translocation involving alpha arm of wheat chromosome 4A and long arm of rye chromosome C. Pairing behaviour of the substitute chromosome with rye and wheat chromosomes in hybrids with rye addition line C and ditelosomic 4A (alpha) confirmed this.
