Triticale is a wheat-rye cross!  Originally bred in Scotland and Denmark.  

Forage yields can be higher than wheat or barley yields. In addition, triticale is more disease resistant in many cases. Many forage wheat fields can have severe stripe rust and barley scald has been a problem in some barley fields in other years. However, triticale in many of these situations be disease free. Triticale works very well in a grazing/haying system. Triticale has also performed well when grown dryland or when irrigation was limited. Perhaps due to its extensive root system and rye background, triticale has good drought tolerance.
