Synopsis In the cross Mindum durum ✕ Vernal emmer, the tough‐threshing character of the emmer parent was inherited in a complex manner. F 3 progenies relatively homozygous for intermediate degrees of threshability were recovered. A two‐factor hypothesis appeared to explain the appearance of clavate heads in this cross between two non‐clavate parents, but was not established conclusively. C1 appeared to cause clavate in the absence of I , an inhibitor. The I gene, or a closely linked gene was one of the major factors for tough threshing.
