Barley is a plant that can be grown in various conditions, from a pedoclimatic point of view, because it has a good drought tolerance. This study tested the drought tolerance of 25 spring barley genotypes using two drought induction methods, the polyethylene glycol method (PEG 10000) at NARDI Fundulea in a controlled climate (M1), and the sodium chlorate method (NaClO3) in the experimental field from ARDS Turda (M2). Drought stress is one of the most important issue for the two-row spring barley yield, since it simultaneously affects many properties at the morphological and physiological level, mainly the production elements and, implicitly, the final yield. Following this study, the Daciana and Jubileu varieties and spring barley perspective genotypes (4 lines from advanced generations To 2168-01, To 2115-10, To 2054-97 and To 2027-10) were shown to be tolerant to both types of induced drought (both in the seedling and adult plant developmental stages).
