The results of the agrobiological evaluation of 74 samples of the world collection of All-Russian Research Institute of Plant Industry named after N.I. Vavilov were analyzed for the period 2013-2016 on individual elements of productivity, yield and the degree of their variation (Cv, %). The earli-est maturing (vegetation period 68-69 days) were the samples of six-rowed barley Leningradsky and Potra. The highest capacity for productive tillering (1.93-2.40 productive stems) had Rupal, Corona, Malva, Chelyabinets 2, Nutans 302, Belgorodets, Talovsky 9. The best graininess of the ear had 18/7, Tduneja, Spratt, Sv. 66905, Milns Golden Promise, Vladimir. According to the mass of 1000 grains (40.0-52.3 g), T-12 (Nutans 129), Yastreb, Belgorodets, Talovsky 9, Yak-401, Nudum 95, Co-dac, Vakula, Potra, Kolchan were the best ones. The samples 18/7, Tduneja, T-12 (Nutans 129), Elf, Belgorodets, Talovsky 9, Heimdal, Nudum 95, Co-dac, Vakula, Kolchan were characterized by the best grain mass from one plant (1.40-1.79 g). Ac-cording to the productivity and resistance to lodg-ing, the most stable during all the years of research were samples M 1913/88 (Czechoslovakia), Asem (Kazakhstan), Etienne (Canada). Their yield reached 555.0-575.0 g / m2, which was 8.2-12.1 % higher than that of the standard grade Acha. The studied barley samples are of practical interest for solving regional selection problems in Eastern Si-beria.
