The study of source material by the traits of early maturity, plant height and resistance to lodging in the conditions of Central Yakutia

Abstract

The peculiarity of the weather conditions of Yakutia highlights the task of reliable ripening of barley varieties in most soil-climatic zones. Seventy six samples of barley of various ecological-geographical and selective origin were studied in collection nurseries for the period 2012-2014 in the conditions of Central Yakutia. The zoned variety Tammi, ultrafast (58 ... 66 days), but not resistant to lodging (3 points) was used as a standard. Compared with the standard, a group of the earliest ripening varieties was identified with a growing season of 60-64 days: Herse (Norway), Nevan (Russia, Irkutsk Region), Piket (Russia, Krasnodar Territory), Nyurbinsky Improved (Russia, Yakutia), JO 1032 (Finland), k-7711 local (Turkey), Nutans 970 (Kyrgyzstan), Belogorsky 95 (Russia, Leningrad Region), Vitim (Russia, Buryatia), Otol (USA, Alaska), JO 1098 (Finland). The most resistant to lodging (7-9 points) were the following varieties: JO 1032 (Finland), Veresk (Russia, Sverdlovsk Region), Coliseum (Russia, Arkhangelsk Region), Tandem (Russia, Kirov Region), Bensa (Belarus), Werner and Svani (Sweden). Thus, according to the study, the initial material was selected for further use in hybridization when creating new early-ripening barley varieties resistant to lodging.
