The father/mother of common Bread wheat: Aegilops tauschii from Dachhigam, Kashmir:
Our common wheat plant Triticum aestivum has a complicated history of origin. In the first step diploid Triticum urartu (till recently considered under T. monococcum) hybridized with possibly Aegilops speltoides and subsequent duplication of chromosomes to yield tetraploid wild emer wheat Triticum dicoccoides. Latter hybridized again with diploid Aegilops tauschii, another duplication of chromosomes to yield hexaploid Triticum aestivum that fills the bellies of people all over the world. I was fortunate to click this immediate progenitor of wheat growing commonly in Dachhigam forest.

I will post it saperately. Please ignore the second image. It is mostly Alyssum. . References:
