Several accessions of durum wheat landraces in the National Gene Bank collection in the IPGR – Sadovo have been tested in a laboratory trial concerning the reaction of young plants to different levels of osmotic stress. The depression along the length of the root and shoot varies according to the stress degree and the genotype. The investigated accessions of durum wheat landraces reveal higher drought tolerance than the registered cultivars of durum and common wheat and barley. Analyses of the results reveal two accessions – 58 125/14 and 58E 126/10 to be of interest for direct application in wheat breeding programs for drought resistance.
