Abstract
The paper highlights the most plastic varieties of spring barley and the varieties with the highest stability in terms of grain yield and mass of 1000 grains under conditions of intensive cultivation technology in the Krasnoyarsk forest-steppe of the Krasnoyarsk region. The article summarizes the results of three years of the research on 12 varieties of spring barley. The researchers observed enviromental plasticity and stability of spring barley varieties both in terms of grain yield and mass of 1000 grains. The data were obtained on the basis of certain varieties capacities to form high and stable yield and mass of 1000 grains under conditions of intensive farming. This data promotes more precise assessment whether a variety fits the expected result. Buyan, Yemelya, Takmak and Omskiy golozernyy 1 appeared to be the most plastic under conditions of intensive farming in terms of grain yield parameters among the studied varieties of spring barley. Buyan, Yemelya, Tanai, Uvatsky appeared to be the most plastic according to the mass of 1000 grains showed the same result varieties. The highest yield stability was observed in varieties Yemelya, Takmak, Buyan, Omskiy Golozernyy 1, and the mass of 1000 grains - in varieties Yemelya, Krasnoyarsk 91, Tanai, Uvat, Oscar. Buyan, Yemelya, Takmak, Omskiy Golozernyy 1 are the most plastic varieties of spring barley according to the crop yield whereas Buyan, Yemelya, Tanai and Uvatsky - by the weight of 1000 grains; varieties Yemelya, Takmak, Buyan, Omskiy Golozernyy 1 are seen as the most stable varieties of spring barley in terms of the crop yield, and a mass of 1000 grains - the varieties Yemelya, Krasnoyarsk 91, Tanai, Uvat, Oscar.

Summary
Полевые исследования проводились на полях конкурсного сортоиспытания Уярского государственного сортоиспытательного участка (ГСУ) в 2017–2019 гг. в Красноярской лесостепи Красноярского края в соответствии с методикой госсортоиспытания [9]. Самой прохладной декадой в среднем за 3 года была вторая декада мая (7,5 ̊С), а самой тёплой – третья декада июня (21,4 ̊С) Средняя температура за период «вторая декада мая – первая декада сентября» составила: в 2017 г. 1. Подекадный ход температур вегетационного периода на Уярском ГСУ в 2017–2019 гг., °С 10-days temperatures during the vegetation period at Uyarsk State Crop Testing Site in 2017-2019, °С. Среднее за 3 года количество осадков было наименьшим в первой декаде июня (4,4 мм), а наибольшим – во второй декаде августа (40,1 мм) Средняя сумма за период «вторая декада мая – первая декада сентября» составила: в 2017 г. Средний за 3 года гидротермический коэффициент (ГТК) наименьшим был в первой декаде июня (0,33), а наибольшим – во второй декаде августа (2,50) ГТК в среднем за период «вторая декада мая – первая декада сентября» составил: в 2017 г. При этом погодные условия лет исследований в целом соответствовали требованиям биологии исследуемой культуры
