Monosomic and disomic substitutions of Imperial rye chromosome C for 4 A 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 4^1 and long arm of rye chromosome C. Pairing behaviour of the
