Abstract
Meiosis was studied in hybrids between Aegilops crassa (Boiss.) Hitch and Hensl. (2n = 6x = 42) having the genomes DD2MCr and six species of Secale. The chiasmata frequency per cell ranged from 6.86 in hybrids with S. cereale to 9.93 in hybrids with S. montanum ssp. dalmaticum. These results provide further evidence that a meiotic pairing control system is operating in Ae. crassa. The Secale genotypes suppress the function of this system in a manner which was inversely related to their heterochromatin content and total DNA content.
