| Abstract | During 2013-2016, resistance to biotic factors (head smut, barley blotches, corn flies) and valuable economic features (yield capacity, plant performance, 1000-grain weight, protein and starch contents) of 150 barley accessions of different geographic origin were determined on provocative background of frit flies and leaf diseases as well as on artificial infection of head smut. Sources of resistance to harmful organisms in combination with economic characteristics (yield capacity of 1 m2 – 64.8-95.0% related to the standard; plant performance – 80.1-136.4% related to the standard; 1000-grain weight- 40.8-56.3 g; protein content – 12.1-15.2%; starch content – 57.8-60.7%) were considered as valuable for breeding programs: in particular, 7 accessions with high resistance to head smut (resistance score 8 -9 points) – ‘Naran’, ‘Yasnyy’, ‘Shchedryy’, ‘Nemchinovskiy 36’, and ‘Buyan’ from Russia, ‘Statok’ from Ukraine and ‘AC Ranger’ from Canada; 1 accession with resistance to barley blotches (resistance score 5 points) - 08-696 from Ukraine; 3 accessions with group resistance (to head smut and barley blotches; resistance scores 9/8 and 6/5 points, respectively) – ‘CDC Mindon’, ‘Ascension’ and ‘Sedna’ from Canada; 1 accession with complex resistance (to head smut, barley blotches and frit flies; resistance score 9, 5 and 5, respectively) – ‘Skhidnyi’ from Ukraine | ||
