In conclusion, there is ample consensus on the absolute need that intensifi cation
of agricultural production necessary to “close the yield gap,” particularly crucial in
the wheat case, has to imply a package of measures that only a changing landscape
of breeding strategies can successfully harness. Technical or other types of limita-
tions will have to be overcome before the latest ground-breaking strategies will be
in place. Fortunately, however, several novel wheat materials, many reinforced with
valuable genes from perennial Triticeae , have been developed in which yet untapped
potential for breeding gains has been effectively unlocked, and many more are
expected to be readily available in the near future. This effort, coupled with the ever
paramount contribution of traditional breeding to incorporate the benefi cial trans-
fers into elite and adapted cultivars, will hopefully soften the highly complex sce-
nario threatening mankind’s staple wheat crop.
