Crude protein extracts were subjected to disk electrophoresis on polyacrylamide gel. The pattern obtained showed a fast and slow series of bands. In the fast series, the eight species of wheat of the Emmer group gave virtually identical eight-band patterns, and the four species of the Timopheevi group gave nearly identical six- or seven-band patterns. The groups consistently differed with respect to four bands. Two of these differences were attributable to the A genome.
