Triticale is a hybrid of:
Triticale is first man-made cereal synthesizing wheat and rye benefits into single allopolyploid species deliberately created by humans. It was created by crossing wheat genus Triticum as female and rye Secale cereale as male. Primary triticale uses tetraploid durum wheat T. turgidum AABB 2n=28 × diploid rye RR 2n=14 producing sterile ABR 21 hybrid doubled to allohexaploid AABBRR 2n=42. Secondary or hexaploid triticale commonly grown today derives from hexaploid bread wheat AABBDD 2n=42 × rye RR 2n=14, chromosome doubled to octoploid AABBDDRR 2n=56 then stabilized to hexaploid AABBRR through c
