Constraints due to global biotic and abiotic stress continue to exist in wheat germ plasm. Novel genetic diversity resides in several annual/perennial Triticeae species that can be introgressed into wheat through intergeneric hybridization, of which Thinopyrum curvifolium is the principle source as it addresses the emphasis here for achieving wheat derivatives resistant to Helminthosporium leaf blight (Cochliobolus sativus). Some additional sources like Th. elongatum (2n=2x= 14) and Secale cereale are also mentioned. The interspecific hybridization strategy offers alien genetic introgression opportunities, for which the closely related Triticum species have a priority. Of these sources, the D genome T. tauschii (Aegilops …

Triticeae is an important tribe in the grass family, Poaceae. It contains the cereals wheat, rye, triticale, and barley as well as a large number of wild species, some of which are utilized as forage grasses. The tribe combines all kind of biological mechanisms and genetic systems: diploids and polyploids; annuals and perennials, inbreeders and outbreeders, and even apomicts. Due to this large variation Triticeae is an excellent model group for research in genetics, plant breeding, genetic diversity, taxonomy, and speciation in plants.
Triticeae is distributed in almost all temperate areas of the world and consists of some 350-450 species …
