Cytogenetic analysis was employed in studying the cause of generation of fertile awned forms in the progeny of plants, which were selected from a speltoid somaclonal wheat line monosomic for chromosome 5A (2n = 41 = 20II + I), had speltoid spikes, and were reproduced by self pollination. On cytogenetic and genetic evidence, chromosome 5A was eliminated and the copy number of chromosome 5B increased in the plants examined. The appearance of an extra chromosome 5B is probably caused by nondisjunction of bivalent 5B in the presence of a telocentric originating from the long arm of chromosome 5A. A difference in meiotic segregation was observed for univalent chromosomes 5A and 5B.
