Abstract	Zymogram analysis was used to identify the Aegilops umbellulata chromosomes that carry the structural genes for particular isozymes. Wheat, Aegilops and wheat-Aegilops hybrid derivative lines (which contained identified Aegilops chromosomes) were tested by gel electrophoresis for isozymes of particular enzymes. It was found that Aegilops chromosome A (nomenclature according to G. Kimber 1967) carries a structural gene for 6-phosphogluconate dehydrogenase, Aegilops chromosome B carries structural genes for glucose phosphate isomerase and phosphoglucose mutase, Aegilops chromosome D carries genes for leaf peroxidases, Aegilops chromosome E carries structural genes for endosperm peroxidases, acid phosphatases and leaf esterases, Aegilops chromosome F carries a gene for embryo plus scutellum peroxidases and Aegilops chromosome G carries structural genes for endosperm alkaline phosphatases, leaf alkaline phosphatases and leaf esterases. The results obtained indicate that chromosome B is partially homoeologous of the wheat chromosomes of group 1 and 4, and chromosome E is partially homoeologous of wheat chromosomes of groups 7 and 4. Circumstantial evidence is also provided about the possible association between chromosomes C, D and A of A. umbellulata respectively with chromosomes 5, 2 and 1 of wheat.
