The current paper has presented the study of productivity, environmental stability and adaptability of 11 Russian grain sorghum varieties of various groups of ripeness in the conditions of the Ural steppe of the Republic of Bashkortostan, conducted in 2015–2019. The purpose of the study was to estimate the grain sorghum varieties according to the parameters of environmental adaptability and stability of productivity in changing environmental conditions. The weather conditions during the years of study were different in temperature and water supply, which made it possible to evaluate the lines in the contrasting cultivation conditions. The index of environmental conditions for grain yield of grain sorghum in 2015 was 0.9, in 2016 it was 1.3, in 2017 it was -1.0, in 2019 it was -1.2. The data completely characterizes the weather conditions of the years of study and their effect on the growth and development of plants. Environmental adaptability (bi) and stability (Ϭ2d) were calculated according to the methods of S.A. Eberchart and W. A. Rassel (1966) interpreted by V. A. Zykin, stress resistance (Ymin–Ymax) was estimated according to the equation of A. A. Rossille, J. Hamblin interpreted by A. A. Goncharenko, productivity range (d) was evaluated according to V. A. Zykin. The varieties ‘Kamelik’, ‘Ogonyok’, ‘Orlovskoe’ turned out to be adaptable (bi was close to 1); the varieties ‘Slavyanka’, ‘Zernyshko’ and ‘Ros’ were responsive to the improvement of growing conditions (bi > 1). Based on a comprehensive estimation of the value of environmental adaptability and stability, the varieties ‘Premiera’, ‘Belochka’, ‘Ogonyok’, ‘Orlovskoe’ were identified as the best ones. These varieties are highly intensive, responsive to the improvement of growing conditions and characterized with high productivity. The paper has collected and presented the material of the long-term study of the environmental adaptability and stability of the grain sorghum productivity in the conditions of the Ural steppe of the Republic of Bashkortostan.

Data of long-term researches (2015–2018) in southern forest-steppe zone of the Republic of Bashkortostan, is justified theoretically and experimentally the mode of irrigation of potatoes on leached chernozems of unsatisfactory, satisfactory and good ameliorative condition of irrigated lands. For the growing periods of potatoes with different heat and moisture supply, the number of watering, the timing of their implementation, irrigation and irrigation norms are established. On lands with unsatisfactory meliorative state the number of irrigation depending on weather conditions of potato vegetation period varied from 0 to 3 (1.5 on average) with average irrigation norm – 990 m3/ha. With satisfactory meliorative state of lands the number of irrigation on average increased from 0 to 4 (2.3 on average) with irrigation norm – 1305 m3/ha. On lands with good meliorative state the number of irrigation was the highest – from 1 to 5 (3 on average) with average irrigation irrigation norm is 1653 m3/ha. It was noted that in the dry periods of potato vegetation the greatest number of watering was carried out (3–5 watering), and in the wet periods (2017) watering was not carried out except for the area with a good reclamation state, where only one irrigation was carried out by the norm of 550 m3/ha. Water consumption of potato was studied in dynamics as a whole during the growing season and the months of the growing season depending on weather conditions of vegetation period and land reclamation condition of irrigated lands, as well as in the control (without irrigation). The lowest total water consumption was in the area without irrigation and averaged 226.8 mm. In irrigated areas, its values increased to 319-353.4 mm. The average daily water consumption varied from 2.12 to 3.3 mm. The highest rates of potato water consumption were observed in June and July, and the lowest – in May and August. In the total water consumption of potatoes on the site without irrigation, the largest share was occupied by atmospheric precipitation and in addition to them the arrival of moisture from the soil. Irrigation water was used in irrigated areas along with precipitation, the share of which was 30.2–46.1 %.

The internal predictive adaptive response (internal PAR) hypothesis predicts that individuals born in poor conditions should start to reproduce earlier if they are likely to have reduced performance in later life. However, whether this is the case remains unexplored in wild populations. Here, we use longitudinal data from a long-term study of Svalbard reindeer to examine age-related changes in adult female life-history responses to environmental conditions experienced in utero as indexed by rain-on-snow (ROS utero ). We show that females experiencing high ROS utero had reduced reproductive success only from 7 years of age, independent of early reproduction. These individuals were able to maintain the same annual reproductive success between 2 and 6 years as phenotypically superior conspecifics that experienced low ROS utero . Young females born after high ROS utero engage in reproductive events at lower body mass (about 2.5 kg less) than those born after low ROS utero . The mean fitness of females that experienced poor environmental conditions in early life was comparable with that of females exposed to good environmental conditions in early life. These results are consistent with the idea of internal PAR and suggest that the life-history responses to early-life conditions can buffer the delayed effects of weather on population dynamics.

Adaptive Ability

Varieties and hybrids which are stable in yield and suitable for cultivation in various soil and climatic zones have a particular value within the conditions of industrial production. New varieties created by breeders should be characterized by the highest yield in favorable conditions, and, at the same time, by the stable yield in other conditions, i.e. be highly accommodative. The aim of the research was to assess environmental stability and plasticity parameters of tomato hybrids according to the main characteristics of yield and then to select the hybrids F1 with high productivity and stability in soil greenhouses. The calculation of adaptive ability and ecological stability indexes was carried out according to the method of A.V. Kilchevsky and L.V. Khotyleva using the ADIS program. As a result, some hybrids were identified as heavy yielding and with high general adaptive ability according to the following parameters: early fruit yield - NikolaçLine‑2, Line‑4×Line‑2, NikolaçLine 19/3, NikolaçLine-9, Line TX-144×Irishka, Line B-3-1-8×Line 19/0, Line C-9464×Line 19/0; on the basis of “commercial fruit yield” - NikolaçLine-2, TX-144×Line-2, Line TX-144×Irishka, TX140×Line-2, Line TX-140×Line 19/3, Line B-3-1-8×Line 19/0, Line C-9464×Line 19/0; by the weight of commercial fruit - NikolaçLine 19/3, Line TX-144çLine 19/3, Line B-3-1-8×Line 19/0. Greater part of yield parameters was stable for hybrids NikolaçLine-2, Line-4×Line-2, TX-140×Line-2, Line B-3-1-8×Line 19/0, Line TX-144×Irishka. Hybrids combinations Azart and Vityaz have successfully passed the test and were recommended for planting on the territory of the Republic of Belarus. Thus, feasibility of ecological stability and plasticity assessment at the final stage of breeding process has been proven. It reduces possibility of errors in choosing hybrids for State testing procedures. Acknowledgments. The research was carried out within the framework of the State Program “Innovative Biotechnologies” for 2010-2012 and for the period up to 2015”, as well as the Interstate Target Program of the Eurasian Economic Community “Innovative Biotechnologies” for 2011-2015.

The use of adaptable fruit and berry cultivars significantly increases the environmental sustainability of horticulture. In 2014–2018, the assortment of plum in the Urals was evaluated using the parameters of productivity, environmental plasticity and stability under the conditions of Chelyabinsk Province. The analysis of environmental plasticity and stability helped to identify adaptable cultivars of Chinese plum (Prúnus salicina L.): ‘Altayskaya yubileynaya’ and ‘Uralskaya zolotistaya’. Plastic plum cultivars included cv. ‘Uralskaya zolotistaya’ (yield: 5.62 t/ha; bi = 1.10; Si2 = 25.7), ‘Uralskaya serebristaya’ (5.53 t/ha; 1.16; 21.3) and ‘Manchzhurskaya krasavitsa’ (5.53 t/ha; 1.21; 33.9); their productivity varied in accordance with changes in environmental conditions. Intensive-type cultivars with high responsiveness to the improvement of growing conditions (bi significantly higher than 1) were cvs. ‘Uvelskaya’ (5.62 t/ha; 1.46; 26.8) and ‘Krasnoselskaya’ (5.04 t/ha; 1.35; 45.7). Cv. ‘Zhemchuzhina Urala’ (4.65 t/ha; 0.05; 22.8) belongs to the cultivars with low plasticity (the bi value close to zero); it is characterized by a weak response to a change in environmental conditions. Cv. ‘Altayskaya yubileynaya’ produces the highest yield (6.16 t/ha) due to its plasticity (bi = 0.91), but has low stability (Si2 = 102.5), while cv. ‘Shershnevskaya’ secures rather high productivity (5.23 tons per hectare) due to high stability (Si2 = 32.7) and medium responsiveness to changes in environmental conditions (bi = 0.75).

<p><strong>Objective.</strong> Assessment of adaptive ability and environmental stability of new early-season maize hybrids created on the basis of inbred lines of hybrid germplasm and alternative germplasms was performed. <strong>Methods.</strong> Field, mathematical, and statistical. <strong>Results.</strong> The results revealed parameters of an adaptive capacity and environmental stability of 11 new inbred maize lines when testing their testcrosses obtained based on 3 testers. The DK285, DK265 and DK412 constant lines, the testcrosses of which had the highest average grain yield (5.49; 5.38; 5.25 t/ha respectively) were distinguished during the research period and they were characterized by high total adaptive capacity (1.48; 1,14; 0.75 respectively) with an intensive and plastic type of response to the variability of growing conditions. It was determined that Cross 267C sister hybrid was distinguished among the tester genotypes by the high values of the effects of the overall adaptive capacity (1.19) and the highest average yield of testcrosses (5.11 t/ha).</p><p><strong>Conclusions</strong>. We observed strong fluctuations in the average yield of grain from 1.96 to 8.13 t/ha during the study period. The level of manifestation of breeding characteristics and parameters of the ecological stability of genotypes depended on weather conditions which changed drastically during the study period and often negatively affected the assessment of genotypes. The high gradient variability of the test environments revealed a significant dependence of the stability-indicating parameters on the productivity of testcrosses. The correlation analysis showed the dependence of the hybrids productivity on the level of implementation of biometric indices of the plant under steppe conditions.</p>
