The most frequent chromosome configuration observed in E. perennis was 5IV + 10II while in the F1 of E. perennis X Z. mays, 5III + 5II + 5I was most commonly seen. In 80% of the selections from the eleventh generation of open pollination of the hybrid, the chromosome number was 38-42. Bivalents and quadrivalents tended to become established while univalents disappeared. Pollen fertility in this group was 0-93%, suggesting the presence of a gene causing sterility.
