What is Cytogenetic and genetic relationships between populations of Aegilops ventricosa Tausch about?

Five samples of Aegilops ventricosa (2n = 4x = 28, genome formula DDNN) from different geographical origins, were crossed in a diallelic scheme . 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 .
