T. durum Desf. resembles T. aestivum, but, the spike rachis of the former is usually hairy at the nodes, and glumes have a crested keel throughout their length. Because breeding and selection of cultivars has been so intensive there is considerable morphological variation in Triticum aestivum. X Triticale is a hybrid between wheat and rye is now grown as a cereal and forage crop, and is commonly planted to stabilize roadsides in N.S.W.
