Significant intraspecific variation was observed. Electrophoregrams of each species were obtained by superposing all the bands found in the same species and in total, 17 bands were observed. Clear differences were found between species in their patterns, which allowed determination of the bands specific to three genomes (A, C and D). Like the diploids, the tetraploids can be divided into two groups on the basis of electrophoretic patterns: A. barbata and A. magna-A. murphyi. It is evident that A. magna-murphyi group is derived from both the A and C genome species of diploids while A. barbata is derived from the A genome species only. The similarity between A. magna and A. murphyi was also confirmed. The hexaploids were derived from A. magna-murphyi group and a D genome ancestor although the last one is not discovered yet.Read More
