Reclassification of Aegilops according to Chennaveeraiah 1960.

This classification [references], which is not well known in the literature, is unusual among cytogenetically-based wheat treatments because Chennaveeraiah disagreed with Bowden's genomic concept of one large genus Triticum. Chennaveeraiah took a different direction, using his evaluation of karyomorphology and plant morphology to justify a division of Aegilops into three genera. Following Eig's treatment of Aegilops and Amblyopyrum, he diverged from the taxonomic tradition by moving the S-genome species into Triticum. The classification is presented here in its original form with corrections for authority names and abbreviations.
