Четыре перспективных гибрида капусты белокочанной среднепозднего срока созревания селекции агрофирмы «Поиск» – F1Универс, F1 Застольный, F1 Поиск 2018 – и позднеспелый гибрид для хранения F1 Континент проходили испытание при разной густоте посадки: 19, 23, 27, 30, 33 тыс. растений/га в условиях Раменского района Московской области. Цель исследования: определить отзывчивость гибридов капусты белокочанной на густоту высадки для их выращивания в Нечерноземной зоне. Место исследований относится к лесной зоне в центральной части Русской равнины. Почвы – аллювиально-луговые среднесуглинистого механического состава. Погодные условия в годы проведения исследований были не совсем благоприятными для выращивания капусты белокочанной: в 2020 году отмечались осадки выше среднемноголетних значений, в 2021 году – жаркая засушливая погода, недостаток влаги, благоприятные условия для развития капустной моли и табачного трипса во время вегетации. Максимальной и стабильной урожайностью за два года исследований отличался среднепоздний гибрид F1 Застольный 144,54 т/га. Для получения наибольших сборов урожая продукции капусты белокочанной рекомендована высадка F1 Застольный при густоте 33 тыс. раст/га, для получения крупных кочанов на разреженных посадках 27 тыс. раст/га. F1 Поиск 2018 – при густоте 33 тыс. раст/га средняя урожайность составила 130,35 т/га, на разреженных посадках 141,4 т/га при густоте 23 тыс. раст/га. Гибрид F1 Универс реализовал свой биологический потенциал продуктивности 125,07 и 126,90 при 33 и 27 тыс. раст/га соответственно. Гибрид F1 Континент менее всех реагировал на изменение густоты посадки, имел наибольшую урожайность при 30 тыс. раст/га 120 т/га. Four promising F1 hybrids of white cabbage bred at Poisk company were tested at different planting density: 19, 23, 27, 30, 33 thousand plants/ha. in the Ramensky district of the Moscow region. F1 Univers, F1Zastolniy, F1 Poisk 2018 – mid-late ripening and F1Continent – late hybrid for storage. Objective of the study: to determine the responsiveness of white cabbage hybrids at different planting densities for their growing in the Non-Black Earth Zone. The research site belongs to the forest zone in the central part of the Russian Plain. Soils are alluvial meadows of medium loamy texture. The weather conditions during the years of the research were not entirely favorable for the cultivation of white cabbage. Precipitation above average annual values was observed in 2020. Hot dry weather, lack of moisture, favorable conditions for the development of cabbage moth and tobacco thrips during the growing season were in 2021. The mid-late hybrid F1 Zastolniy was distinguished by the maximum and stable yield over 2 years of research. Its yield was 144.54 t/ha. Planting F1Zastolniy was recommended at a density of 33 thousand plants/ha to maximize the yield of white cabbage production; large heads of cabbage should be obtained on sparse plantings at 27 thousand plants/ha. The average yield of F1Poisk 2018 was 130.35 t/ha with a density of 33 thousand plants/ha, 141.4 t/ha on sparse plantings with a density of 23 thousand plants/ha. The F1 Univers hybrid has realized its biological productivity potential of 125.07 and 126.90 at 33 and 27 thousand plants/ha, respectively. Hybrid F1 Continent reacted least of all to changes in planting density, had the highest yield at 30 thousand plants/ha 120 t/ha.

Relevance. The most complex and common physiological disease on the cabbage is a tip burn, associated with impaired Ca2 + transport inside the plant. Of all the ways to control this physiological disease, the most effective is the cultivation of tolerant hybrids. Material and methods.The aim of the research was to evaluate the mid-late and late ripening F1 hybrids of white cabbage for a tip burn and to determine the degree of hybrids responsiveness to calcium deficiency depending on weather conditions. The studies were carried out at breeding and experimental plot of the vegetable growing department at All-Russian Rice Research Institute in 2017-2019 on drip irrigation. Material - hybrid combinations of ARRRI breeding.Results. The manifestation of a physiological disturbance called “burn of the top of the inner leaves of the cabbage head” or “tip burn” on individual hybrids was observed during all years of cultivation, but to a different degree; The greatest damage to the heads was recorded in the years (2017 and 2019) with high productivity, which is due to the intensive assimilation ability against the background of warm sunny weather. In 2019, the manifestation of burns was noted in 25% of hybrids, which allowed them to be divided into 4 groups, depending on the degree of damage and the spread of the disease.It was established that hybrids with overmature standing for 2.5-3 weeks and also hybrids that were promptly removed at the time of mass technical ripeness had a high degree of damage. The lines that are most often found in hybrid combinations with signs of burns (269-824, Agr1321, 269Jas13, Byum112, Yas25, etc.) were identified, but it is rather difficult to assume the nature of inheritance, and, therefore, to develop the principle of pair selection when developing relatively stable hybrids also not yet possible.

Приведены результаты селекционной работы по созданию нового гибрида капусты белокочанной F1 Атлант. Цель исследований: создать отечественные гибриды капусты белокочанной для хранения на основе ЦМС, с высокими вкусовыми качествами, относительно устойчивые к болезням, пригодные для механизированной технологии выращивания в Нечерноземной зоне. Исследования проведены в 2004–2019 годах во ВНИИО-филиале ФГБНУ ФНЦО (д. Верея Раменского района Московской области). Место исследований относится к лесной зоне в центральной части Русской равнины с суммой осадков 593 мм за год. Сумма положительных температур выше 10 °С составляет 2075 °С, период с температурой воздуха более 10 °С – 134 дня. Почвы – аллювиально-луговые среднесуглинистого механического состава. Подобрана коллекция линий из 18 образцов среднепозднего и позднего сроков созревания и изучена по основным хозяйственно ценным признакам, устойчивости к болезням, уровню самонесовместимости. Установлено, что для перевода на ЦМС основу наиболее перспективны линии 346, 808 p, Ко5–41 с завязываемостью 7–11 семян при самоопылении цветков. В потомстве сохраняли ценные признаки фертильной линии. При первом скрещивании завязываемость семян высокая 18–29 шт. на стручок, при последующих постепенно снижается до 12–17 семян на стручок в зависимости от генотипа. В 2016 году выделена наиболее урожайная комбинация с массой кочана 2,5 кг на основе ЦМС. В 2017–2019 годах новый гибрид проходил испытание в условиях Московской области, отличался повышенной урожайностью 98,3–99,6 т/га и превзошел стандарт F1 Экстра на 14,2–24,6%. Одновременно проведена оценка родительских линий по семеноводческим признакам и синхронности цветения. При скрещивании родительских линий завязываемость семян составляет 10–16 шт. на один стручок. В 2019 году поздний гибрид на основе ЦМС под названием F1 Атлант, предназначенный для потребления в свежем виде и хранения передан в Государственное сортоиспытание. The results for breeding work to create a new hybrid of white cabbage F1 Atlant are presented. The purpose of the research: to create domestic cabbage hybrids for storage based on CMS, with high taste, relatively resistant to diseases, suitable for mechanized cultivation technology in the Non-Chernozem zone. The studies were carried out in 2004–2019 at the ARRIVG-branch of FSBSI FSVC (village Vereya Ramensky district Moscow region). The research site belongs to the forest zone in the central part of the Russian Plain with a total precipitation of 593 mm per year. The sum of positive temperatures above 10 °C is 2075 °C, the period with air temperatures above 10 °C is 134 days. Soils are alluvial meadows of medium loamy texture. The collection of lines was selected from 18 samples of medium-late and late maturity and studied for the main economically valuable traits, disease resistance, level of self-incompatibility. It was found that lines 346, 808 p, Ko5–41 with a set of 7–11 seeds with self-pollination of flowers are the most promising for transfer to the CMS basis. The offspring retained valuable traits of the fertile line. The setting of seeds during the first crossing is high, 18–29 pcs/pod; with subsequent crosses, it gradually decreases to 12–17 seeds per pod, depending on the genotype. In 2016, the most productive combination was selected with a head mass of 2.5 kg based on CMS. In 2017–2019, the new hybrid was tested in the conditions of the Moscow region, was distinguished by an increased yield of 98.3–99.6 t/ha and exceeded the F1 Extra standard by 14.2–24.6%. At the same time, the assessment of parental lines was carried out on the basis of seed-growing characteristics and the synchronism of flowering. The set of seeds is 10–16 seeds per pod when crossing parental lines. In 2019, a late hybrid based on CMS was submitted to the State Variety Test under the name F1Atlant and is intended for fresh consumption and storage.

One of the modern selection tasks in vegetable growing is quality products improving, obtaining high yields of environmentally safe wide assortment vegetables. To the new varieties of vegetable crops including winter white cabbage are specified new requirements such as market competitiveness, resistance to unfavorable environmental conditions, heat resistance of the varieties and F1 hybrids. The article is shown investigation results about studies of exogenous treatment by solutions on the base of physiologically active compounds of hormonal nature on the started process of stem extension stage activation and flowering of winter white cabbage plants. For the first time in the Dagestan conditions has been studied the possibility of hormonal regulation of the premature stem extension stage and flowering prevention of winter white cabbage after the initiation of natural induction. In our studies with an early planting there are not more than 20% of blooming plants, most varieties showed a high propensity to premature stem extension stage and flowering. The possibility of the hormonal exogenous regulation of the unfavorable winter white cabbage flowering has been revealed. The most pronounced effect on the transition to stem extension stage and flowering were provided by auxin nature preparations. In particular, treatment with NAS at a dose of 5 mg / l significantly reduced the number of blossom plants, krezatsin (50 mg / l) had a similar effect, but it was less pronounced. The use of cabbage in winter crops makes it possible to obtain two or three yields per year from the same area. Creation and introduction into production of promising and high-yielding varieties and hybrids will allow increasing production and reducing its cost.

В данной статье представлены результаты сравнительной оценки 11 сортов клевера лугового и одного образца-дикороса, проведённой в Пермском НИИ сельского хозяйства в 2018–2019 годах. Все селекционные сорта сформировали полноценные первый и второй укосы или отаву в оба года использования. Дикорастущая форма формировала только один укос, демонстрируя особенность позднеспелого одноукосного типа. Сорта Кретуновский и Ранний 2 показали себя как типичные раннеспелые двухукосные. Другие сорта занимали промежуточное положение. Наибольший сбор сухого вещества обеспечивал образец-дикорос в оба года при крайне различных погодных условиях (1,266 и 1,259 кг/м2 соответственно). Дикорастущая форма и сорт Ранний 2 обеспечивали стабильные урожаи зелёной массы и сухого вещества независимо от возраста и погодных условий. Образец дикорастущего клевера имел более однородный фенотип по сравнению с сортом Пермский местный — стандартом для позднеспелого типа, что указывает на большую генетическую однородность. Согласно всесторонней оценке, включающей степень перезимовки, урожайность зелёной и сухой массы, характер цветения, созревания, формирования и конечный урожай семян, образец-дикорос имеет отличительные признаки позднеспелого (одноукосного) типа и может использоваться в качестве исходного генетического материала для дальнейшей селекции позднеспелых одноукосных сортов клевера лугового, характеризующихся экономически ценными свойствами: высокой устойчивостью к неблагоприятным условиям окружающей среды, высокой и стабильной урожайностью зелёной массы и семян. Исследования будут продолжены с оценкой ряда образцов дикорастущих форм клевера лугового, обнаруженных в 2019 году в природных биоценозах Пермского края. This article deals with the competitive trial of 11 varieties and 1 wild genotype of red clover conducted at the Research Institute of Agriculture in 2018–2019. All the varieties provided good yields of green mass both in the first and second cuts. Wild genotype provided only one cut as long-season one-cut type. “Kretunovskiy” and “Ranniy 2” performed as typical short-season two-cut varieties. Wild genotype produced the highest yield of dry matter (DM) under contrast weather conditions (1.266 and 1.259 kg/m2, respectively). Wild genotype and “Ranniy 2” formed stable yields of green mass and DM regardless of time period and weather. Wild genotype showed homogeneous phenotype compared to “Permskiy mestnyy” — long-season standard variety indicating high genetic uniformity. Such traits as winter hardiness, green and dry mass yields, flowering pattern, seed maturation, formation and production were evaluated. According to this evaluation wild genotype performed as long-season (one-cut) type showing high resistance to unfavorable conditions, high and stable yield of green mass and seeds. Therefore, it can be used a source of economically important traits for future breeding programs of red clover. Further investigations will focus on the evaluation of wild genotypes of red clover found in the Perm region in 2019.

Background. Studies into the adaptability of the genetic diversity of cultivated plants and their wild relatives to various environments are induced by global climate change. Introduction of adaptive wheat cultivars resistant to environmental stressors is the basis for stable harvests. This article presents the results of a research into the adaptive value of indigenous durum wheat varieties and improved cultivars released in different years in Azerbaijan.Materials and methods. The experiments were carried out in the foothills of Mountainous Shirvan under unsecured non-irrigation at Gobustan Experiment Station of the Research Institute of Crop Husbandry. In 2012–2014, contrasting in weather conditions, levels and structure of yield were analyzed. VIR’s guidelines were used to study 42 durum wheat varie ties, including 10 landraces. The years of study differed sharply in rainfall. Selyaninov’s hydrothermal coefficient was used to assess the conditions of growing seasons.Results. Mostly modern cultivars of the semi-intensive type were distinguished for a set of agrobiological traits. Adaptability coefficients (0.81–1.23) showed that the response of the studied varieties to unfavorable conditions was highly expressed. Indigenous landraces ‘Ag bughda’ and ‘Bozak’, old breeding varieties ‘Arandani’, ‘Ag bughda 13’, ‘Kahraba’ and ‘Mirbashir 50’, and new cultivars ‘Karagilchig 2’ and ‘Barakatli 95’ had the highest adaptability coefficients. The first of them demonstrated stable yield, and the latter two were also resistant to stressors.Conclusion. Durum wheat yields under the conditions of moderately continental climate in Mountainous Shirvan depended on the number and weight of grains per ear. The varieties identified for the best adaptability are recommended to be included in crosses to develop new plastic cultivars of durum wheat.

The locations of the Stone Age on the Volgograd region territory have been known since the beginning of the XIX century. However, purposeful Stone Age sites explorations had only started after the Sukhaya Mechetka site was discovered by A.P. Koptev and M.N. Grischenko in 1951. The data accumulated on series of stratified sites in Volgograd Region makes it possible to outline two significant groups of them. One of the groups belongs to the Lower Volga basin. The other group is associated with the ramified network of gullies and ravines and multiple tributaries of the Don. The Don is the fourth longest river on the Russian Plain; its basin taken in the Volgograd Region is several times larger than the Volga basin taken in the area. The relatively flat landscape of the Don plain, saturated with small rivers, gullies and ravines, as well as stone raw materials available for mining, have been creating favorable conditions for human habitation since the Middle Paleolithic. The well-known Paleolithic and Mesolithic sites are found both in the watersheds and in the floodplain-terrace areas of the Middle Don. The near-mouth section of the Kurmoyarsky Aksai river – the Don tributary in Kotelnikovo District – and the surroundings of Kremenskaya village in Kletskaya District are standing out in terms of being studied. The stone industry detected in the lower layers of the multilayered site Schlyakh indicates that the Don plain was inhabited by people during the Middle to the Upper Paleolithic transition. The prospects of further searches for Stone Age sites in the Middle Don Basin had already been proven by the discovery of at least forty sites in previous decades. Further archaeological research will help to discover new stratified sites with impressive collections of stone and bone items, which will make it possible to draw analogies with synchronous sites in the territories adjacent to the Volgograd region.

Агрохолдинг Поиск предлагает отечественным овощеводам гибриды капусты белокочанной, позволяющие организовать конвейер производства овощной продукции. Одновременно с этим на базе ВНИИО филиала ФГБНУ ФНЦО и ЗАО Куликово идет разработка и совершенствование технологий их выращивания. В 2019 году овощеводам предложена технология выращивания ряда гибридов на примере ЗАО Куликово , позволяющая получать урожай на уровне лучших зарубежных аналогов. В статье представлены результаты испытания отечественных гибридов в Московской области на базе ВНИИО филиала ФГБНУ ФНЦО на различных фонах минерального питания: контроль без удобрений, N120P120K180, N180P180K270. Почва опытного участка относится к типу аллювиальных луговых насыщенных почв: среднесуглинистая, окультуренная. Погодные условия в годы проведения исследований были не совсем благоприятны для роста и развития капусты белокочанной, особенно 2018 год, характеризующийся жарким летом и небольшим количеством осадков. Дефицит влаги компенсировали дополнительными поливами. В 20152019 годах изучены следующие гибриды: F1 Княгиня, F1 Герцогиня, F1 Континент (селекции Агрохолдинга Поиск ), F1 Идиллия, F1 Дмитровский (совместные селекционные достижения ФГБНУ ФНЦО и Агрохолдинга Поиск ), F1 Флагман (селекции Агрохолдинга Поиск и ООО Селекционная станция им. Н.Н. Тимофеева ), F1 Бомонд Агро (гибрид Агрохолдинга Поиск , ФГБНУ ФНЦО и ООО Селекционная станция имени Н.Н. Тимофеева ). Урожайность товарной продукции на фоне без удобрений варьировала от 53 до 57,3 т/га, максимальная урожайность отмечена у гибрида F1 Бомонд Агро 57,3 т/га. Такую урожайность гибриды обеспечивают за счет своего генетического потенциала. При внесении удобрений в дозе N120P120K180 урожайность товарной продукции варьировала от 61,6 до 76,8 т/га, прибавка урожая составила 16,2335,21. Максимальное значение отмечено у гибрида F1 Герцогиня 76,8 т/га. При увеличении нормы полного минерального удобрения до N180P180K270 наибольшей урожайностью товарной продукции обладают гибриды F1 Идиллия и F1 Герцогиня 89,3 т/га и 84,9 т/га соответственно. Гибрид F1 Континент в 2019 году имел наибольшую урожайность среди гибридов 91,2 т/га, прибавка за счет внесения удобрений составила 70,79. Высокая урожайность объясняется высокой морфологической выравненностью, сильной корневой системой и высокой стандартностью продукции 100 по всем вариантам опыта.Poisk Agro Holding offers domestic vegetable growers hybrids of white cabbage, allowing to organize a conveyor for the production of vegetable products. At the same time, there is a development and improvement of technologies for their growing on the basis of ARRIVG branch of FSBSI FSCVG and close corporation Kulikovo. The technology for growing a number of hybrids was proposed to vegetable growers in 2019 using the example of close corporation Kulikovo, which allows you to get a crop at the level of the best foreign analogues. The results are presented in this article on the testing of domestic hybrids in the Moscow region on the basis of ARRIVG branch of FSBSI FSCVG on various backgrounds of mineral nutrition: control without fertilizers, N120P120K180, N180P180K270. The soil of the experimental plot is alluvial meadow saturated soils: medium loamy, cultivated. Weather conditions during the years of research were not entirely favorable for the growth and development of white cabbage, especially in 2018, which is characterized by hot summers and low rainfall. The moisture deficit was compensated by additional watering. In 20152019, the following hybrids were studied: F1 Knyaginya, F1 Gertsoginya, F1 Kontinent (selection of Poisk Agro Holding) F1 Idillya, F1 Dmitrovsky (joint selection achievements of the FSCVG and Poisk Agro Holding), F1 Flagman (selection of Poisk Agro Holding and Breeding Station after N.N. Timofeev Ltd) F1 Bоmond Agro (a hybrid of Poisk Agro Holding, FSCVG and Breeding station after N.N. Timofeev Ltd). Productivity of marketable products varied against 53 to 57.3 t/ha without fertilizers the maximum yield was observed for the F1 Bomond Agro hybrid 57.3 t/ha. Hybrids provide this yield due to their genetic potential. Productivity of marketable products ranged from 61.6 to 76.8 t/ha when fertilizers were applied at a dose of N120P120K180, yield increase was 16.2335.21. The maximum value was observed for the F1 Gertsoginya hybrid of 76.8 t/ha. Hybrids of F1 Idillya and F1 Gertsoginya possess the highest yield of marketable products with an increase in the rate of full mineral fertilizer to N180P180K270 89.3 t/ha and 84.9 t/ha, respectively. In 2019, the F1 Kontinent hybrid had the maximum yield among hybrids of 91.2 t/ha, the increase due to the application of fertilizers was 70.79. High productivity is explained by high morphological uniformity, a strong root system and high standard production of 100 for all variants of experience.
