The sources of biological properties and economically valuable traits for barley selection

The purpose of the study was to identify promising varieties for practical selection of barley. In Kemerovo Region in 2013-2016 110 barley varieties had been studied. From them there were 0.9 % from Sweden; France - 0.9 %; Germany - 8.1 %; the Czech Republic - 10.8 %; Latvia - 5.4 %; Estonia - 0.9 %; the USA - 11.7 %; Belarus - 4.5 %; Ukraine - 4.5 %; Kazakhstan - 2.7 %; Russia - 55 %. They were compared with control varieties: Biom, Nikita (Western Siberia). According to the duration of vegetation season, 3 groups of barley were allocated: 1-st group with short vegetation period (up to 73 days) - 14 %; 2-nd group with average period (74-78 days) - 56 %; 3-rd group with a long period (more than 78 days) - 14 %. The representatives of the first group were Biom (Novosibirsk Region), Scarlett (Germany), Idumeja (Latvia), Nutans 290 (Saratov Region), Rubicon (Krasnodar Region), Tandem (Kirov Region). On average for 4 years in standard varieties Biom and Nikita 243-282 productive stalks were formed on 1 m2...
