Inheritance of Head Characters in Tetraploid Wheat Hybrids: I. Glume Tenacity And Head Type in Mindum Durum × Vernal Emmer1

  1. Glenn S. Smith2



In the cross Mindum durum ✕ Vernal emmer, the tough-threshing character of the emmer parent was inherited in a complex manner. F3 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. C1appeared 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.
