Abstract
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 squarrosa) accessions and some of the A genome species (T. boeoticum, T. monococcum and T. urartu) are being exploited.
