Popis: Meiotic analysis of 13 hybrids, 3 of which are new combinations, shows that the M genome of Triticum ovatum has undergone substantial modification. The pivotal U genome is much closer to its diploid progenitor, Triticum umbellulatum. However, the possibility exists that it too has been somewhat modified. If this is substantiated, then some reconsideration of the pivotal–differential theory of evolution in the wheat group may be required.Key words: genome analysis, meiosis, Aegilops, wheat.
