Abstract Zymogram analysis was used to identify the barley chromosomes that carry the structural genes for particular isozymes. Wheat, barley, and wheatbarley hybrid derivative lines (which contained identified barley chromosomes) were tested by gel electrophoresis for isozymes of particular enzymes. It was found that barley chromosome 4 carries structural genes for acid phosphatase and β amylase isozymes, barley chromosome 5 carries genes for phosphoglucose isomerase and malate dehydrogenase isozymes, and that barley chromosome 2 carries a gene for at least one glucose-6-phosphate dehydrogenase protomer. These results reinforce previous conclusions that barley chromosome 4 shows homoeology with wheat chromosome group 4 and that barley chromosome 5 shows homoeology with wheat chromosome group 1.
