“…The current study was devoted to investigating the effect of different oil concentrations on two rye varieties–Krona and Valdai. Previous studies have shown that these varieties differ in winter hardiness and their resistance to low temperatures, acidification, and high content of aluminum ions in the soil [ 31 , 32 , 33 ]. The current study revealed that a significant decrease in shoot biomass was observed in the Krona variety at 6% oil concentration in the soil (by 24% lower compared to the control) and in the Valdai variety at 12% oil concentration in the soil (by 25% lower compared to the control).…”

“…To the best of our knowledge, the current study will be one of the earliest studies aimed at investigating the effects of different concentrations of crude oil in the soil on growth, oxidative stress, and antioxidative response in rye plants. Moreover, since genotypes within the species are known to vary in their resistance to environmental stress, two rye varieties were chosen for the current study due to their resistance to low temperatures, soil acidity, and increased concentration of aluminum ions [ 31 , 32 , 33 ]. The results of the current study will contribute to an increased knowledge about (i) the growth and physiological responses of two rye varieties to various levels of oil pollution in the soil, (ii) oxidative stress induced in rye plants in conditions of soil pollution with crude oil, and (iii) the reaction of low molecular weight antioxidants and antioxidative enzymes in two rye varieties growing on the oil-contaminated soil.…”

Rye (Secale cereale L.) is one of the most important cereal crops in Eastern and Northern Europe, showing better tolerance to environmental stress factors compared to wheat and triticale. Plant response to the crude oil-polluted soil depends on plant species, oil concentration, time of exposure, etc. The current study is aimed at investigating the growth, oxidative stress and the response of antioxidative system of two rye varieties (Krona and Valdai) cultivated on crude oil-contaminated soils at different concentrations (1.5, 3.0, 6.0, and 12.0%). Inhibition of rye growth was observed at crude oil concentrations of above 3% for above-ground plant parts and of above 1.5% for roots. A decrease in content of chlorophyll a and total chlorophylls in Krona variety was detected at 1.5% oil concentration in soil and in Valdai variety at 3% oil concentration. Compared with the control, the content of malondialdehyde was significantly increased in the Krona variety at 3% oil concentration and in Valdai variety at 6% oil concentration. The crude oil-induced oxidative stress was minimized in rye plants by the enhanced contents of low-molecular antioxidants (proline, non-protein thiols, ascorbic acid, phenolic compounds) and activities of superoxide dismutase, catalase, ascorbate peroxidase, and glutathione peroxidase. The strongest positive correlation was detected between the content of malondialdehyde and contents of proline (r = 0.89–0.95, p ≤ 0.05) and phenolic compounds (r = 0.90–0.94, p ≤ 0.05) as well as superoxide dismutase activity (r = 0.81–0.90, p ≤ 0.05). Based on the results of a comprehensive analysis of growth and biochemical parameters and of the cluster analysis, Valdai variety proved to be more resistant to oil pollution. Due to this, Valdai variety is considered to be a promising rye variety for cultivation on moderately oil-polluted soils in order to decontaminate them. At the same time, it is necessary to conduct further studies aimed at investigating oil transformation processes in the soil-rye system, which would make it possible to determine the efficiency of using this cereal for soil remediation.

Winter rye has a high adaptive capacity to abiotic and biotic stressors compared to other winter crops (wheat, triticale, barley, and oats). High resistance of winter rye to adverse environmental factors and a wide range of its uses increase interest in this crop. The purpose of this research was to evaluate the adaptive capacity of population and hybrid varieties of winter rye and to identify varieties suitable for the soil and climate conditions of Eastern Siberia. A number of winter rye varieties of various geographical origins were tested during three field seasons. In all the field seasons, the population varieties (Tagna, Mininskaya, and Chulpan) were the most productive and most resistant to adverse environmental factors compared to the hybrid wheat (KWS Aviator, KWS Prommo, and KWS Ravo). Statistically significant (p < 0.001 in 2019/2020 and p < 0.001 in 2021/2022) differences in field survival and yield between the population and hybrid varieties were noted.

“…Объективную оценку комбинационной способности родительских линий дает анализ гибридов F 1 от диаллельных скрещиваний. В то же время если с одним сортом-тестером можно определить ОКС родительских форм, то схема, в которой тестером служит набор селекционно ценных инбредных линий, позволяет охарактеризовать их СКС без диаллельного скрещивания (14). Изучение пяти инбредных линий кукурузы в качестве тестеров показало (15), что лучшими в этом случае будут формы с повышенной урожайностью и высокими эффектами ОКС.…”

Получение гетерозисных гибридов F 1 взамен сортов-популяций-одно из значительных достижений в селекции XX века. Рожь (Secale cereale L.) как строго перекрестно-опыляемая культура весьма перспективна для гетерозисной селекции. Успешность гибридной селекции ржи зависит от наличия гомозиготных линий с высокой комбинационной способностью. Скрещивание линий по схеме топкросса позволяет эффективно выявлять и использовать для синтеза высокогетерозисных гибридов только лучшие генотипы. В представленной работе впервые охарактеризованы уникальные высокогомозиготные инбредные линии озимой ржи, полученные на основе трех российских генопулов, и выявлены линии с высокой комбинационной способностью, перспективные для селекции на продуктивность и качество. Цель наших исследований заключалась в оценке общей и специфическую комбинационной способности инбредных линий озимой ржи с помощью метода полных топкроссов. Тестовые скрещивания по этой схеме провели в 2016 году на изолированных участках, где материнской формой послужили 5 стерильных линий с цитоплазмой типа Пампа (Н-649, Н-577, Н-842, Н-1058 и Н-1185), а отцовской-4 мужски фертильные линии (Н-451, Н-1011, Н-1247 и Н-1071), которые были тестерами. Всего получили 20 простых межлинейных гибридов F 1. Их испытание провели в 2017 году на делянках площадью 8,0 м 2 в 3 повторениях при норме высева 500 зерен на 1 м 2. Урожайность гибридов F 1 варьировала от 5,02 до 7,90 т/га при аналогичном показателе у популяционного сорта Валдай 6,50 т/га. Наиболее продуктивным оказался гибрид F 1 (Н-649 ½ Н-1011), который при урожайности 7,9 т/га превысил стандарт Валдай на 21,5 % (Р  0,95). В целом по опыту частота гибридов F 1 с достоверно высоким конкурсным гетерозисом составила 7 из 20 (или 35 %). Основной причиной варьирования урожайности у гибридов F 1 стали различия их родительских форм по комбинационной способности. В дисперсию признака урожайности существенный вклад вносили как общая (ОКС), так и специфическая (СКС) комбинационная способность линий, однако на долю эффектов ОКС приходилось 91,1 % всей изменчивости урожайности, а на СКС-только 7,7 %. Из этого следует, что основной компонент генотипической вариансы признака урожайности-аддитивное взаимодействие генов, но не внутрилокусное доминирование. В то же время высокое соотношение варианс ОКС/СКС указывает на весьма значительную генетическую дивергенцию инбредных линий, взятых для скрещивания. Достоверно высокую ОКС имели стерильные аналоги линий Н-1185 и Н-649, а также отцовская линия-тестер Н-1011. Существенно более низкой общей комбинационной способностью обладали короткостебельные линии Н-577 и Н-1071. Высокие эффекты СКС показали стерильные линии Н-1058 и Н-649, а также тестеры Н-1071 и Н-451. Выявлена положительная корреляция между оценками ОКС линий и высотой растений (r = 0,85±0,10), массой 1000 зерен (r = 0,80±0,13) и массой зерна с колоса (r = 0,64±0,21). Полученные результаты свидетельствуют о важном значении селекции инбредных линий озимой ржи на высокую продуктивность и положительную сочетаемость признаков крупнозерности ...
