Abstract
One polyhaploid (2n=3x=21) ofCritesion iranicum (von Bothmer) A. Love (6x=42) was obtained following interspecific hybridization with tetraploidC. bulbosum (L.) A. Love, presumably through chromosome elimination. Meiotic pairing in pollen mother cells averaged 2.43 univalents, 0.12 rod bivalents, 2.37 ring bivalents, and 4.53 trivalents. The data indicate that the three genomes fromC. iranicum are homologous with equal affinity. This confirms thatC. iranicum is an autohexaploid.
