Metaphase I chromosome pairing of the hybrids, accounting for all the possible genetic combinations, was analysed. Only bivalents were formed in some hybrids, while multivalents were scored in other ones. Seed storage proteins, gliadins and albumins, were also analysed by means of polyacrylamide gel electrophoresis. Based on the presence of multivalents in hybrids, and on the differences in seed protein profiles, the samples could be grouped into two clusters. Meiosis was regular in hybrids obtained within samples of the same group, while multivalents were present in hybrids involving a sample of one group and one of the other. The evolutionary trends in Ae. ventricosa are discussed.  aAegilops ventricosa  acytogenetics  aevolution  aChromosomal polymorphism  aSeed proteins  aWild wheats1 aGALASSO, I.1 aHAMMER, K.1 aPERRINO, P.  tEuphyticagv.79, p.81-85, 1994
