Triticum carthlicum

Triticum carthlicum Nevski, 1934, the Persian wheat, is a wheat with a tetraploid genome.

Some scholars refer to it as T. turgidum subspecies carthlicum. Recent research suggest that T. carthlicum originated from a cross between domesticated emmer wheat and T. aestivum.

Diseases
T. carthlicum is the source of Pm4b, a resistance gene encoding a MCTP kinase used in hexaploid wheat. Pmb4 confers powdery mildew resistance.
