Early and late durum wheat varieties, T,durum/T.dicoccoides interspecific lines, acessions of the wild Triticeae species Aegilops geniculata Roth and Hordeum chilense Roem.et Schult., and Ae.geniculata/T.durum and H.chilense/T.durum amphiploids were compared for root attributes and some agronomical traits as earliness, tiller number and above-ground biomass production.A wide variation was observed for most traits and strong correlations were noted between them.The tested genetic material however significantly differed for root develoment, root depth, tiller number and earliness.H.chilense exhibited a lower shoot: root dry weight ratio.Primary root axis was found significantly longer in the interspecific tetraploid lines and Ae.geniculata/T.durum amphiploids.
