A classification of the genus Aegilops by means of genome-analysis was published in 1954 (Cytologia 19). At that time the study of the 6x species, Ae. triaristata, Ae. crassa and Ae. juvenalis was still incomplete. Recently, with the assistance of my collaborators, I have obtained enough data on the basis of the morphological as well as genome-analytical analyses to draw the conclusion that the third genome of the hexaploid Ae. triaristata is a modified M and that of Ae. crassa is D. The genome-type of Ae. juvenalis was also ascertained.
A complete classification of the whole genus Aegilops is given in the following table.
