MANY investigators have reported the appearance in common wheat (Triticum aesti-uum L.) of speltoid types simulating Triticum spelta L. Generally these are due to the loss of the incompletely dominant gene Q on chromosome 5A (formerly chromosome IX) by aneuploidy (7) or by irradiation (3). Compactoid types ascribed to the action of the same gene, Q, but having some similarity to T. compactum Host were obtained in the same irradiation experiments from common wheat by Mac Key (3). Earlier, Unrau (9) located the gene governing compactum on chromosome 2D (formerly chromosme XX). This paper reports the occurrence of a mutation in common wheat simulating a lesser-known wheat species, T. sphaerococcum Perc., and the inheritance of this mutant character.
