“…The value of average yield of a variety in contrasting environmental conditions shows the highest degree of correspondence between variety genotype and environmental factors [18]. The high yield on average for 5 years had the variety Zilant (4.52 t/ha), the middle positions were occupied by the varieties Tatarskaya 1 and Tantana (4.27 t/ha and 4.24 t/ha, respectively), the low yield was demonstrated by the variety Radon (4.05 t/ha).…”

Rye grain yield in the Russian Federation has had a positive trend over the last 12 years, with an increase of 0.45 kg/ha per year. The Volga Federal District is the centre of rye growing in Russia. We evaluated the adaptability of Tatarstan winter rye varieties of own selection - first (Tatarskaya 1, Radon) and last generation (Tantana and Zilant) in terms of grain yield. From 2019 to 2023, these varieties will be tested in a competitive variety trial at the Tatar Agricultural Research Institute, FRC Kazan Scientific Centre of RAS. The breeding strategy was not focused on increasing the "upper limit" of yield, but on reducing the varieties' sensitivity to the environmental conditions of the production area. Cultivar plasticity ranged from 0,743 (Tatarskaya 1) to 1,246 (Radon). The research results showed that the latest generation varieties (Zilant, Tantana) are characterised by higher yields, plasticity and good stability compared to earlier developed varieties. The cultivar Zilant achieved the optimum balance of ecological variability parameters.

“…The analysis of this trait gave an opportunity to predict the variety response to unfavorable environmental conditions, which allowed realizing their potential productivity [4,5]. According to the above mentioned concept, the current winter barley breeding is aimed at developing the varieties with the improved adaptability, high and stable productivity with low energy and resource costs [6,7]. This direction coincided with the world-wide trend of the grain producing countries to obtain not maximum, but optimal and stable grain productivity over the years [8,9,10].…”

There has been estimated the ecological adaptability and stability of winter barley varieties in the conditions of the Rostov region. There were studied 4 varieties and 6 lines of winter barley developed in the FSBSI “Agricultural Research Center “Donskoy”. The estimation was conducted according to the S.A. Eberchart, W.A. Rassel method (1966, ed. by V.A. Zykin), using a statistical processing software Statistica 10 and Excel. During the years of study (2017-2019), the environmental conditions varied significantly, which allowed reliably estimating the environmental adaptability and stability of the studied varieties and lines. The analysis of adaptability and stability resulted in identification of such responsive varieties as ‘Marusya’ and ‘Yerema’, as well as the line ‘Parallelum 1976’ with linear regression coefficients more than 1. The varieties ‘Marusya’ and ‘Yerema’ were the best ones among the studied varieties and lines, showing high and stable productivity over the years of study. According to the study results the variety ‘Vivat’ showed a sufficiently high level of adaptability. The variety ‘Timofey’ and the lines ‘Parallelum 1979’, ‘Parallelum 1981’, ‘Pallidum 1972’ showed a sufficiently high level of stability.

“…Практически это может быть достигнуто только при соответствии экологических требований сорта почвенно-климатическими условиями его возделывания. Чем более неблагоприятны и непредсказуемы погодные условия, тем большим должен быть «запас» экологической устойчивости сортов [4,5]. Такой постулат особенно важен при создании сортов для условий Европейского Севера.…”

Ключевые слова: картофель, межвидовые гибриды, продуктивность, экологическая пластичность, стабильность, селекционная ценность. Перспективные гибриды картофеля как будущие новые сорта являются одним из определяющих факторов повышения продуктивности культуры, стабилизации отрасли и повышения качества конечного продукта. Поэтому одной из важнейших задач селекции является поиск путей управления селекционным процессом создания скороспелых межвидовых гибридов картофеля с высокими хозяйственно-ценными признаками. На начальных стадиях работы возникает необходимость проверки их в различных географических зонах и выявления их адаптационной способности, т. е. приспособляемости к конкретным почвенно-климатическим условиям. В статье представлены результаты исследований по выявлению перспективных межвидовых гибридов по параметрам их адаптивности и пригодных для выращивания в условиях Европейского Севера за 2014-2017 гг. и испытанных в четырех точках (Ленинградская, Архангельская и Мурманская области и Республика Карелия). В результате проведенных исследований получены два сорта картофеля: Евразия (гибрид 5403/2) и Сиверский (гибрид 3602/28). Сорт Евразия допущен (2017 г.) к использованию в условиях Северо-Западного региона.
