Published: May 2024

There has been presented a three-year estimation of winter wheat samples according to adaptability indicators, the trait ‘productivity’, ‘winter resistance’, ‘1000-grain weight’, and ‘number of productive stems per m2’. The purpose of the study was to estimate the adaptive potential of winter common wheat varieties in the forest-steppe of Western Siberia at different sowing dates. The study was conducted in the laboratory for field crop breeding, seed production and cultivation technologies based on SibRIPCB, the branch of Institute of Cytology and Genetics, SB RAS (Novosibirsk region) in 2018–2022. The objects of study were 5 winter common wheat varieties developed by the SibRIPCB, a branch of the Institute of Cytology and Genetics SB RAS. Sowing was carried out in three periods (the first was in August 20, the second was in September 1 and the third was in September 10) with an SSFC-7 seeder in 5 repetitions, the recording plot area was 10 m², the placement of the plots was randomized, the crops were laid in weedfree fallow. As a result, there was established that, according to the trait ‘productivity’, the varieties ‘Novosibirskaya 2’ (bi = 1.42; δd² = 0.08) and ‘Novosibirskaya 3’ (bi = 1.35; δd² = 0.08) combined ecological adaptability and stability. The variety ‘Novosibirskaya 3’ also combined adaptability and stability according to the trait ‘number of productive stems per m2’ (bi = 1.09; δd² = 468.94). The winter variety ‘Krasnoobskaya’ is capable of consistently giving high yields ((Ymax+Ymin)/2 = 4.92; (Sc = 3.42); Hom = 26.2) and maintaining the density of productive stems ((Ymin–Ymax) = -280; Sc = 280.8; (Ymin+Ymax)/2 = 513; Hom = 8.9) at different sowing dates. The variety ‘Pamyati Chekurova’ is responsive to improvements in environmental conditions according to the trait ‘productivity’ (bi = 1.10; KM = 2.20), ‘winter resistance’ (bi = 1.53; KM = 2.72), ‘number of productive stems per m2’ (bi = 1.22; KM = 2.2).

Published: May 2024

The purpose of the study was to identify the effect of quantitative traits on grain productivity of maize hybrids depending on moisture availability. The study was carried out on the breeding field of the laboratory for maize breeding and seed production of the FSBSI “ARC “Donskoy” in 2020–2023. The soil of the experimental plot was ordinary blackearth, with a humus layer thickness of 140 cm. The climate is characterized by aridity with unstable moisture. The years of the study were contrasting in temperature and moisture availability (HTC 0.49–0.83). Due to the uneven distribution of precipitation during a vegetation period of maize, the temperature regime through the months and moisture availability had even greater differences (HTC 0.11–2.28). The objects of research were 96 maize hybrids. The main method for developing hybrids was an interline hybridization. There has been identified a stable correlation between grain productivity and quantitative traits in each of the four years of study, when ‘one ear weight’ was r = 0.34±0.09 – 0.64±0.08 and ‘number of grains in a ear row’ was r = 0.35±0.09–0.58±0.08. The specific climatic conditions of some years of the study (one year out of four) influenced the lack of correlation between amount of productivity and quantitative traits with ‘number of ears per plant’ (r = 0.11 ± 0.10 in 2022), ‘number of grains per ear’ (r = 0.01±0.10 in 2023), ‘grain yield during threshing (r = 0.04±0.10 in 2023). The correlation between productivity and traits was subject to even greater variability depending on weather conditions with ‘ear attachment height’ (r = 0.01±0.10–0.40±0.09), ‘plant height’ (r = 0.16±0.10–0.38±0.09), ‘ear diameter’ (r = -0.02±0.10–0.43±0.09), ‘1000-grain weight’ (r = -0.14±0.10–0.45±0.09). In all years of the study, there were no correlation between productivity and such traits as ‘number of grain rows’ (r = -0.27±0.09–0.17±0.10) and ‘ear length’ (r = 0.01±0.10–0.29±0.09).

The current paper has presented the study results conducted on the experimental plot of the Falenskaya breeding station of the branch of the FSBI FANC of the North-East in 2021–2023. The purpose of the study was to evaluate the collection hulled oat varieties according to grain productivity and adaptability parameters in the soil and climatic conditions of the Kirov region. The materials for the study were 9 collection oat varieties and the standard variety ‘Krechet’. According to the trait ‘productivity’, there have been estimated adaptability parameters. During the testing years, the studied variety samples differed significantly in productivity variability (V = 16.8–30.0 %). The factor ‘year’ had the greatest effect on the formation of oat yields (90.3 %). In the arid year of 2021, the varieties’ productivity was low (276–401 g/m2), with a negative index of environmental conditions (Ij = -163), in the most favorable year of 2022, it was 463–682 g/m2 and Ij = 104, respectively. The variety samples ‘k-3967 0144’ (-190 g/m2) and ‘15584 Mutant 258’ (-214 g/m2) were characterized by high stress resistance. High genetic flexibility of mean productivity under contrasting conditions was established in the variety samples ‘15472 Sumphony’ (504 g/m2), ‘k-3967 0144’ (496 g/m2) and ‘15340 Uran’ (487 g/m2). There have been identified such gene sources as plastic ‘k-3967 0144’, ‘15472 Sumphony’, ‘15340 Uran’, ‘k-3951 0146’, ‘k-3954 0149’ (IEP = 1.13–1.0), and with high stability of the trait ‘productivity’ ‘k-3967 0144’, ‘15584 Mutant 258’, ‘k-3954 0149’ (SF = 1.47–1.78). Low variability and high homeostaticity were found in the variety samples ‘k-3967 0144’, ‘15584 Mutant 258’, ‘k-3954 0149’ (V = 16.8–22.8 %; Hom = 31.31–20.75) with a high stability index (Is = 5.95–4.38). The adaptability coefficient has confirmed the high adaptability of variety samples ‘k-3967 0144’, ‘15472 Sumphony’ and ‘15340 Uran’ (KA =112.3–108 %). In adaptive breeding for further work, the varieties ‘k-3967 0144’, ‘15584 Mutant 258’, ‘k-3954 0149’, ‘15472 Sumphony’, ‘15340 Uran’ are of great interest, since they are the most adaptive in terms of the sum of ranks. Based on a comprehensive estimation of productivity and adaptability parameters, ‘k-3967 0144’ was recognized as the best variety sample, which can give a large mean productivity (526 g/m2) in changing weather conditions.

The purpose of the current study was to conduct an environmental testing and give a comprehensive estimation of the adaptability parameters of modern grain sorghum varieties developed by the FSBSI “ARC “Donskoy”. Weather conditions during the years of study were different, which made it possible to estimate varieties under contrasting cultivation conditions. The year’s conditions index was the highest in 2019 and 2023 (+0.76 and +1.03), and the lowest (-1.21) in the acutely arid year of 2020. The main effect on the productivity formation of the grain sorghum varieties was made by the conditions of the year (49.8 %) and the minor effect was made by the genotype of the variety (31.0 %). The varieties ‘Ataman’, ‘Zernogradskoe 88’, ‘Luchistoe’, ‘Zernogradskoe 53’ were found to be more productive (> 4.6 t/ha) and have a higher adaptability coefficient (108.8–117.2 %). Intensive samples (bi > 1) were ‘Zernogradskoe 53’, ‘Ataman’, ‘Luchistoe’, ‘Zernogradskoe 88’. Extensive varieties (bi < 1) were ‘Orlovskoe’, ‘Velikan’ and ‘Krymbel’ (st.). The varieties ‘Luchistoe’, ‘Ataman’,’ Zernogradskoe 88’ (S2d = 0.02–0.04) had high stability indicators, and the varieties ‘Ataman’, ‘Luchistoe’, ‘Zernogradskoe 88’, ‘Zernogradskoe 53’ had high overall adaptive capacity (TAC). The maximum indicators (115–131 %) of the stability level were established in the varieties ‘Ataman’, ‘Luchistoe’, ‘Zernogradskoe 88’. The rating estimation of adaptability parameters has shown that the early ripening intensive varieties ‘Ataman’ (68 points), ‘Luchistoe’ (67 points) and ‘Zernogradskoye 88’ (61 points) are the best and the most suitable ones for cultivation in the Donbass.

The purpose of the current study was to estimate the potential of soybean varieties of various ecological and geographical groups according to the trait ‘seed weight per plant’ and to identify varieties with high adaptability to the conditions of the Ryazan region. The objects of research were 33 soybean samples from the world collection, which differed in morphological and biological characteristics. The soybean variety ‘Sibiriada’ (Russia), zoned for the Central region, was taken as the standard variety. Field trials were carried out on dark gray forest soil at the Institute of Seed production and Agrotechnologies, branch of the Federal Budgetary Scientific Institution “FRAEC VIM”, located in the Ryazan region in 2021–2023. In order to characterize the adaptability parameters, there have been used such indicators as homeostatic index (Hom), coefficient of variation (CV), stability factor (SF); range of the indicator ‘seed weight per plant’ (d), standard deviation (σ); adaptability coefficient (AC); stability level indicator (SLI) and stress resistance (Ymin–Ymax), calculated using appropriate methods. There has been established that according to the trait ‘seed weight per plant’ the varieties ‘Georgiya’, ‘Snezhana’ and ‘Chera 1’ (Russia) had the lowest value of variation with Cv,%≤20.0. It was found that the varieties ‘Georgiya’ and ‘Snezhana’ (Russia) were the most stable to external environmental changes. This was evidenced by the lowest values of the coefficient of variation (Cv = 12.9 and Cv = 14.0 %, respectively) and high homeostaticity (Hom = 31.3 and Hom =28.9). The greatest variability and low homeostaticity were found in the soybean varieties ‘Vereteyka’ (Hom = 1.69, Cv = 58.4 %) and ‘Elena’ (Hom = 2.17, Cv = 50.3 %), which characterized the low adaptability of these varieties to the conditions of the Ryazan region. As a result of the estimation of the genotypes studied in the trial according to the triat ‘seed weight per plant’, it was established that the varieties ‘Georgia’ (Russia), ‘Snezhana’ (Russia), ‘Chera 1’ (Russia), ‘Garmoniya’ (Russia) were of great breeding value for improving adaptability and stability in the forest-steppe agroclimatic zone of the Ryazan region.

This study focused on the impact of climate change on the livelihood of coastal people. The study used primary and secondary data to complete the study. The climatic components are changing gradually, consequently, the impact of adversity on livelihood is severe in coastal areas. This research has found the perceptions of coastal people regarding climate change and it’s devastation. Coastal people faced change-induced disasters such as cyclones, floods, tidal surges, salinity intrusion, and erosion that affected the coastal communities and their livelihoods. The study found people lost their livelihood sectors, especially agricultural activities, fish farms, fishing culture, cattle farms, business, daily working opportunities, and daily labor. However, due to the challenges during and after the disasters, they cannot easily resume their regular occupations and jobs, including agricultural activities, fishing farms, fishing and cropping businesses, daily labor, seasonal labor, and workers for fishing farms. Furthermore, the coastal people lost their property and lives, particularly settlements, agricultural land, and crops, to climate change-induced adversity. The marginal farmers and laborers are the main losers during and after disasters because they have no backup money for survival. Many of them took loans from local financial institutions and money lenders. The research will provide guidelines for the coastal community and policymakers to mitigate the impact of adversity.
