Estimation of the initial material of spring barley in the Rostov region

The current paper has presented the study results of collection samples spring barley. purpose was a comprehensive research barley varieties and lines various ecological geographical origin in order to identify most valuable economic biological forms for targeted use breeding programs department seed production Federal State Budgetary Scientific Institution Agricultural Research Center “Donskoy”. carried out on experimental plots FSBSI “ARC “Donskoy” 2017–2019. objects were 85 samples. seed-plot formed from best institutions regions, which domestic (FSBSI FRC All-Russian Institute genetic resources plants named after N.I. Vavilov, “Donskoy, “National grain P.P. Lukyanenko”, North-Caucasus FSAC, etc.), as well European Union (England, Germany, France, Czech Republic, Denmark, Latvia), Canada, Belarus, Ukraine. sowings row method with spacing 15 cm Wintersteiger Plotseed seeder; seven-row, an area 10 m 2 . seeding rate 450 germinated seeds per 1 m² without repetitions. standard variety ‘Ratnik’ sown every 20 numbers seed-plot. forecrop sunflower. There made phenological observations, estimated varieties’ resistance lodging diseases, assessed productivity conducted structural analysis points according estimation system main economically traits given Methodological recommendations studying world oats (2012). As result, there identified following complex traits, ‘Kazer’, ‘Azov’, ‘Tan 1’, ‘Divny’, ‘Chelyabinsky 99’, ‘Khadzhibey’, ‘Raushan’, ‘Agat’, ‘Suzdalets’, ‘Bagrets’, ‘Rus’, ‘Elf’, ‘Rakhat’ (Russia); ‘Nord 071111’, ‘Obolon’, ‘Odessa 22’, ‘Donetsk 14’, 15’ (Ukraine); ‘Perun’, ‘Prestige’ (Czech Republic); ‘Viking’, ‘Philadelphie’ (Germany). are going be used further
