Plant breeding plays an important role in increasing grain production and improving its quality. Currently, the de[1]velopment of new ecologically adaptable varieties that can more effectively use the climatic and soil resources of the regions is of great importance. The purpose of the current study was to analyze the parameters of ecological adapt[1]ability and stability of varieties and lines of the competitive variety testing (2018–2020) in the Rostov region. There have been studied five winter barley varieties ‘Timofey’, ‘Erema’, ‘Vivat’, ‘Marusya’, ‘Foks 1’ and six winter barley lines ‘Pallidum 1899’, ‘Pallidum 1972’, ‘Parallelum 1976’, ‘Parallelum 1979’, ‘Parallelum 1980’, ‘Parallelum 1981’ developed by the FSBSI “ARC “Donskoy”. The sowing was carried out with a Wintersteiger Plotseed seeder, accounting plots area was 10 m². The forecrop was peas. The placement was systematic; the number of repetitions was 6. The factor ‘year’ had the greatest influence on the formation of productivity with 97.07%. The analysis of environmental condi[1]tions showed that there were more favorable growing conditions in 2018 (Ij = +1.27), and unfavorable ones in 2019 (Ij = -1.62). The productivity of the varieties ‘Erema’ (9.4 t / ha; +0.7), ‘Marusya’ (9.7 t / ha; +1.0) and the line ‘Pallidum 1972’ (9.4 t / ha; +0.7) exceeded that of the standard variety. There has been established the varieties and lines ‘Timofey’, ‘Pallidum 1972’, ‘Parallium 1979’, ‘Parallum 1981’ had increased stress resistance. The varieties ‘Erema’, ‘Marusya’ and the line ‘Pallidum 1972’ had a higher compensatory ability. According to the analysis of adaptability, the varieties ‘Erema’, ‘Marusya’, ‘Foks 1’, as well as the line ‘Parallelum 1976’ were identified as responsive with linear regression coefficient values above one. The lines ‘Pallidum 1972’, ‘Parallelum 1979’, ‘Parallelum 1981’ and the variety ‘Marusya’ consistently produced high yields. The lines ‘Pallidum 1972’, ‘Parallum 1979’ and ‘Parallum 1981’ possessed high stability index (L) and PUSS index.

The improvement of yield stability largely depends on responsiveness to favorable growing conditions and resistance to stress factors. The promising varieties should have stable yields, resistance to unfavorable environmental conditions, such as winter resistance and drought tolerance. In this regard, a purposeful breeding for adaptability, i.e. resistance to stress factors is of great importance. The purpose of the research was to study the adaptability and stability of winter barley varieties. The estimation was carried out on the experimental field of the FSBSI ARC “Donskoy”, which is located in the southern zone of the Rostov region. Through three years, 28 winter barley varieties of domestic and foreign breeding were studied. The location of the plots is systematic in double sequence; the area is 10 m². The calculation of ecological plasticity was carried out according to the method of S. A. Eberchart, W. A. Rassel (1966) (ed. by V. A. Zykin (2005)) using the statistical data processing program Statistica 10. It has been established that the most responsive varieties (bi > 1) to the improvement of growing conditions were ‘Erema’ (bi = 1.60), ‘Foks 1’ (bi = 1.64), ‘Skala’ (bi = 1.61), ‘Explorer 8’ (bi = 1.81) and ‘Capten’ (bi = 2.02). These varieties due to a high level of agricultural technology provide maximum yields. At an extensive background it is better to use the varieties ‘KWS-2-117’ (bi = 0.28), ‘KWS – 2–234’ (bi = 0.48). The most stable varieties of the studied foreign ones were the varieties ‘Wintwalt’ and ‘Explorer 4’ (σ²d = 0.04). Through the years of study, the variety ‘Marusya’ (RF) had the highest yield with a linear regression coefficient bi = 0.54, which indicates great stability of this variety.

Productivity of winter barley varieties is a main characteristic for their wide introduction into agricultural production. Yields and quality of grain are usually formed under influence of a complex set of conditions. Grain productivity depends on such factors as cultivation technology, hydrothermal regime, tolerance to unfavourable weather conditions. Plant moisture supply is the main factor for obtaining high yields of winter barley in the eastern part of the Rostov region. The study was conducted in the years of 2014-2016, which were characterized with different moisture supply. There were studied the varieties ‘Master’, ‘Tigr’, ‘Timofey’ and ‘Erema’ developed by the FSBSI ARC “Donskoy”. On average three varieties ‘Master’ (4.26 t/ha), ‘Timofey’ (4.18 t/ha) and ‘Erema’ 4.37 t/ha) gave the largest yields for three-year period of study. On average for three-year period of study the greatest quantity of protein was found in the variety ‘Tugr’ (11.7%), the greatest amount of starch was found in the variety ‘Timofey’ (59.2%).

Grain quality of winter bread wheat is an urgent issue in Russia and in the world. The traits and properties of grain that characterize the quality are formed in the field under the effect of weather and climatic conditions. The current study was carried out in 2017–2019. The objects of the study were 12 varieties and 3 promising lines of winter bread wheat of the Competitive Variety Testing. The variety ‘Ermak’ was used as a standard variety. The purpose of the study was to carry out a comparative estimation of grain quality of the varieties and promising lines of winter bread wheat, to identify the variation of traits over the years and to determine the effect of growing conditions on the formation of grain quality. There has been established that the studied varieties and lines formed nature weight from 799 g/l (the variety ‘Aksiniya’) to 830 g/l (‘Yubiley Dona’) and corresponded to the 1-st quality class. There have been identified the varieties ‘Etyud’ (62%; Cv = 6.6%), ‘Ermak’ (62%; Cv = 7.0%) and the line ‘1005/14’ (68%; Cv = 8.1%) with a combination of high values of the general hardness and insignificant variation of the trait over the years. There has been determined that the variety ‘Nakhodka’ (14.11%; Cv = 3.6%) and the line ‘1261/13’ (14.10%; Cv = 6.1%) were characterized by the maximum protein percentage and low values of the coefficient of variation. There has been established that the varieties ‘Aksiniya’ (4.5 points; 7.9%) and ‘Tanais’ (4.0 points; 2.5%) combined a high baking value with the stability of the trait. When estimating the effect of the factors “genotype”, “year of study” and their correlation on the characteristics of grain quality, there has been found that general hardness (52.59%), mass fraction of grain protein (58.31%), dough deformation (57, 78%), valorimetric value (46.01%), volume of bread (41.77%) and general baking assessment (51.24%) were largely dependent on genotype. The growing conditions had an effect on the formation of the quantity and quality of gluten and the P/l ratio.

Grain production stabilization is one of the main criteria for the development of agriculture in Russia. In this regard, in modern breeding, when developing varieties, considerable attention must be paid to their adaptability, i.e. parameters that ensure stable productivity in various growing conditions. The purpose of the current study was to estimate the spring barley samples according to the trait ‘yield’ for adaptability to the arid conditions of the Stavropol Territory and their further use in breeding work. The material for the study were 86 spring barley samples. In order to determine the stability, there was used a variance coefficient (V%) according to the method of B.A. Dospekhov (2014). The ecological adaptability (bi) and the environment index (Ij) were determined according to the method of S.A. Eberhart and W.A. Russell (1966) as presented by V.Z. Pakudin (1984). Homeostaticity (Hom) was assessed according to the method of V.V. Hangildin (1981). Stress resistance was determined according to the equations of A.A. Rosielle and J. Hamblin as presented by A.A. Goncharenko (2005). There were identified the highly productive samples ‘Mamlyuk’ (389 g/m2) and ‘Stirling’ (378 g/m2), possessing high responsiveness to improving environmental conditions (bi = 1.44–1.21), variability (V = 58.9–51,2%) and low stress resistance (Ymin – Ymax = -538–488). Such genotypes are capable of forming high yields in favorable conditions and may be of interest for breeding high-intensity varieties. The samples weakly responsive to changes in growing conditions were distinguished by high stability and homeostaticity according to the trait ‘yield’, namely ‘Nutans 74840’ (Hom = 2.88; V = 38.4%) and ‘Veles’ (Hom = 2.56; V = 38.5%), as well as the adaptable variety ‘Getman’ (Hom = 2.89; V = 40.6%). These samples are the most adaptive to the arid conditions of the Stavropol Territory and regions with similar cultivation conditions. They are recommended for use in breeding work.

Представлены результаты испытаний образцов моркови столовой в условиях Московской и Ростовской областей. Цель исследований – провести сортоиспытание моркови столовой в двух эколого-географических зонах и выявить различия по отдельным качественным и количественным признакам. Исследования проведены в 2017-2018 годах. Метеорологические условия 2017-2018 годов в Московской области (МО) складывались неблагоприятно для развития моркови в фазу «вилочки» и начала формирования корнеплодов. В Ростовской области жаркая и сухая погода в июле-августе отрицательно влияла на рост развитие корнеплодов. Материалом для исследований служили 3 сорта и 3 гибрида моркови столовой отечественной селекции: Корсар, Шантенэ королевская, Нанте, F1 Таврида, F1 Поиск 32, F1 Поиск 41. Полевые опыты были заложены согласно общепринятым методикам. Образцы значительно отличались по длине корнеплода: корнеплоды, выращенные в Ростовской области, имели большую длину, чем в Московской области, за исключением сорта Шантенэ королевская (11,9 и 13,2 см соответственно) и гибрида F1 Поиск 32 (18,4 и 15,8 см соответственно), у которых наблюдали обратную тенденцию. По урожайности сорта и гибриды, полученные в МО, значительно превосходили аналогичные образцы, выращенные в Ростовской области. На юге в течение двух лет испытаний лучше всех показал себя сорт Шантенэ королевская (55,0 и 54,9 т/га). В Московской области наибольшую урожайность показывал сорт Шантенэ королевская (75,0 и 69,5 т/га соответственно), гибриды F1 Поиск 32 (73,2 и 69,0 т/га), F1 Поиск 41 (69,0 и 64,7 т/га). Распространение листовых болезней в условиях Московской и Ростовской областей сводилось к тому, что в 2018 году по сравнению с 2017 годом образцы были более устойчивы, кроме гибридов F1 Таврида и F1 Поиск 41.The results of testing samples of carrots in the conditions of Moscow and Rostov regions are presented. The purpose of the research is to carry out a variety testing of carrots in two ecological-geographical zones and to identify differences in individual qualitative and quantitative characteristics. Research conducted in 2017-2018. The meteorological conditions of 2017–2018 in the Moscow Region (MO) were unfavorable for the development of carrots in the “fork” phase and the beginning of the formation of roots. In the Rostov region, hot and dry weather in July and August negatively influenced the growth of the development of roots. The material for research was 3 varieties and 3 carrot hybrids of the domestic breeding: Corsar, Shantene korolevskaya, Nante, F1 Tavrida, F1 Poisk 32, F1 Poisk 41. Field experiments were established according to generally accepted methods. The samples differed significantly in the length of the roots: roots grown in the Rostov region had a greater length than in the Moscow region, with the exception of the Shantene korolevskaya variety (11.9 and 13.2 cm, respectively) and the hybrid F1 (18.4 and 15.8 cm, respectively), which observed the opposite trend. In terms of yield, the varieties and hybrids obtained in the MO were significantly superior to similar samples grown in the Rostov region. In the south, during two years of testing, the Shantene korolevskaya variety (55.0 and 54.9 t/ha) performed best of all. In the Moscow region, the highest yield was shown by the variety Shantene korolevskaya (75.0 and 69.5 t/ha, respectively), hybrids F1 (73.2 and 69.0 t ha), F1 Poisk 41 (69.0 and 64. 7 t/ha). The spread of leaf diseases in the conditions of Moscow and Rostov regions was reduced to the fact that in 2018 compared to 2017, the samples were more stable, except for the F1 Tavrida and F1 Poisk 41.

In the present study, fifty-two mungbean (Vigna radiata) genotypes were evaluated for seven morphological traits at three different environments in South Indian state Tamil Nadu, namely Virinjipuram (E1), Eachangkottai (E2), and Bhavanisagar (E3) during Kharif 2017, 2018, and 2019, respectively. The data collected were subjected to variability and correlation analyses, followed by stability analysis using additive main effects and multiplicative interaction (AMMI) model, genotype and genotype × environment interaction effects (GGE) biplot. Variablility was observed among the genotypes for the following traits viz., plant height, days to fifty per cent flowering, number of pods per plant, pod length, number of seeds per pod, hundred seed weight and grain yield. Correlation analysis showed that the trait number of pods per plant was significantly associated with grain yield. The G × E was smaller than the genetic variation of grain yield as it portrayed the maximum contribution of genotypic effects (61.07%). GGE biplot showed E3 as a highly discriminating and representative environment. It also identified environment-specific genotypes viz., EC 396111 for E1, EC 396125 for E2 and EC 396101 for E3 environments. The genotypes with minimum genotype stability index (GSI) viz., V2802BG (7), HG 22 (13), and EC 396098 (13) were observed with wide adaptation and high yields across all the three environments. In summary, we identified stable genotypes adapted across environments for grain yield. These genotypes can be used as parent/pre-breeding materials in future mungbean breeding programs.
