The  article provides  the  results of  studies on  estimation of 50  covered  and 37 naked barley  collection  samples on  resistance  to osmotic stress. The estimation was done  in  laboratory conditions. Sucrose with concentration corresponded  to pressure of 14 atmospheres was used as osmotic solution. Artificial drought significantly reduced seed germination of most samples. Compared  to  the control, under osmotic stress only 1.0% of samples had single germinated seeds on  the 3-d day of  the experi ment. Laboratory estimation has shown that differences on germination ability under osmotic stress do not depend on the place of  sample origin. For example, among samples from Great Britain  there were both forms with resistance higher  than average (Canasta)  and  sensitive  to osmotic  stress  (Crusades). Weak  significant  correlation was pointed out between drought  resistance  in laboratory experiment and field productivity (r = 0.28). More close relation was established between resistance to osmotic stress and number of grain  in  the ear  (r = 0.52) as well as ear productivity (r = 0.53). Resistant  to osmotic stress samples more  than 30% exceeded a standard variety by productivity under drought conditions. For further breeding activity drought resistant samples were  selected: of husked barley  – Tandem, Chelyabinsky 96, Chelyabinsky 99, Sonet  (Russia), Firlbeks Union  (Switzerland), Lamba  (Denmark), Canasta  (Great Britain), Buck  (Canada), Bonita  (Argentina);  of naked barley  – Omsky  golozerny 1
(Russia), CBSS06YCA 0044S, CBSS06YCA 0019S, CBSS06YCA 0018S (Canada), Azure (USA), k-18079 Local (India).
