Abstract
Inheritance of glume hairiness and ear density of 8 agronomic varieties of common wheat, Triticum aestivum was studied by monosomic and conventional analyses. Glume hairiness is controlled by a single dominant gene, Hg, located on chromosome XIV. Spike density characterizing the subspecies compactum is determined by spike length but not by the number of spikelets per ear. Short ear length of compactum is controlled by a single dominant gene, C, located on chromosome XX. The different spike length found between vulgare varieties is associated with the number of spikelets per ear and controlled by polygenes.
