10.1 Introduction
Progenitor species that contributed the constituent triple genomes, designated AA,
BB and DD found in the allohexaploid genome of common wheat ( Triticum aesti-
vum ) have to a large extent been defi ned. Aegilops tauschii has been established as
the D genome donor to common wheat (Kihara 1944 ; McFadden and Sears 1946 ).
In contrast to the narrow geographic distribution of the other progenitor species,
Ae. tauschii extends over a wide geographic range from eastern Turkey to China.
Early taxonomic classifi cations based on spike morphology placed Ae. tauschii
into two subspecies-ssp tauschii and ssp. strangulata (Eig 1929 ). Under subspe-
cies tauschii , there were three varietal taxa classifi ed as anathera , meyeri and
typica whereas in subspecies strangulata a monotypic varietal taxa also referred
