Triticale, the first man-made cereal crop, has been obtained by crossing wheat withTriticale is the first man-made cereal.
It has been produced by an intergeneric cross between wheat (Triticum) and rye (Secale cereale); the name combines the two generic names.
The F1 hybrid is sterile, so its chromosome number is doubled with colchicine to obtain the fertile allopolyploid.
Hexaploid triticale is obtained from tetraploid wheat and rye, and octaploid triticale from hexaploid wheat and rye.
It combines the high yield and grain quality of wheat with the hardiness and disease resistance of rye.
So triticale has been obtained by crossing wheat with rye.
