Evidence has been gathered of the occurrence of secondary association in E. coracana through the scoring of PMCs based on the number of bivalent groups they had in, as observed from polar view.
Secondary association results indicate at the polyploid nature of the species with 9 as the possible basic chromosome number. The data available at present preclude, however, the further consideration of the problem concerning the auto- or allopolyploid nature of the species.
