Abstract
Genetic variation at 21 enzyme loci was studied in Aegilops comosa and Ae. uniaristata, the two species belonging to section Comopyrum of Aegilops. In Ae. comosa, the mean number of alleles per locus was 2.00 and the proportion of polymorphic loci was 0.667; in Ae. uniaristata they were 1.19 and 0.143, respectively. The two species were genetically distant from each other (I=0.561) supporting the previously assigned different genome symbols, M and N.
