Relevance. Therefore, at present, varieties with an average seed size are used for the production of canned "green peas". In this regard, it is important to create varieties with a mass of 1000 seeds less than 150 g for the production of premium canned food.Methods. The object of research was the lines of hybrids of vegetable peas of different ripeness groups with a low weight of 1000 seeds.Results. At the initial stage of the work, plants with a low mass of 1000 seeds and green cotyledons were selected and brought to constant lines over several years. Over the years of sampling, the weather conditions were with sharp changes in temperature and precipitation. This made it possible to single out samples with low variability of the selected characters based on the totality of characters. In 2018-2019, the selected lines were studied according to the characteristics of productivity and manufacturability during the period of technical ripeness in the nursery of competitive variety testing of vegetable peas. To determine the duration of the technical ripeness period and its relationship with the yield, the green peas were harvested in three periods, starting with the minimum density indicators (34-35 units) and with an interval of three days. When determining the fractional composition of green peas, sample 4.12 was isolated, which received the varietal name Smaylik. Green peas of this variety had a fairly high uniformity and small grain diameter with a predominance of fractions of 5-8.5 mm and 8.6-9.9 mm. Sample 12.12 was close to Smaylik in its performance. According to the results of competitive variety testing, the Smaylik variety in 2019 was transferred to the State variety testing of the Russian Federation.

Relevance. The purpose of the research was to produce a new medium-ripe, high-yielding variety of vegetable peas with the usual type of leaf to expand the variety in the now used conveyor variety selection of the Krymsk EBS VIR Branch.Materials and methods. The experience was laid on the fields of the Krymsk EBS VIR Branch (Russia, Krasnodar Region, Krymsk) in 2019-2020. Varieties and strain were evaluated in a competitive variety testing. Sowing was carried out with a selection seeder SKS-6-10. The plot area was 10 m2 , the experiment was repeated four times. In the phase of technical ripeness, the sheaves were selected for description and the yield was taken into account. The conservation of green peas was done at the Tech Evaluation Lab.Results. Competitive variety testing in the mid-ripeness group was held by two strains 2014/7 and 344/16. The strain 2014/17 for green pea yields surpassed the standard "Parus" and G-344/16 in both years of study. Fresh and processed green peas were rated by the Tasting Commission at 5.0 and 4.8 points, respectively. High yield is achieved due to the paired beans on the peduncle and a large number of grains in the bean, up to 10 pieces. The grain in technical ripeness has a dark green color and the linear dimensions are 9.0x8.1 mm. In biological maturity, the seeds are intensely green, angular-compressed with a mass of 1000 pieces. 188-225 g.Conclusion. The results of field and laboratory analyses carried out on the complex of economicvaluable characteristics made it possible to distinguish the strain 2014/7, which in 2020 was transferred to the State Variety Testing under the name "Patriot". It is recommended as a supplement to the existing set of vegetable pea varieties of the Krymsk EBS VIR Branch in the mid-ripe group.

Background. The efficiency of heterotic breeding is determined by reasonable selection of the lines with the best combining abilities and important breeding traits. It is possible to use the variability potential of the majority of traits when the level of resistance to the main diseases and pests is quite high. The most harmful disease of maize is common or boil smut (caused by Ustilago zeae (Beckm.) Unger). The breeding of resistant lines and hybrids of maize is the most rational, cheap and ecologically safe way to fight the disease. The initial stage of breeding work is the identification of pathogen-resistant forms.Materials and methods. In 2017, 594 accessions of six main Zea mays L. subspecies were studied using a score scale against the natural infectious background at the Kuban Experiment Station of VIR. The weather conditions (downpours and abrupt daily temperature fluctuations) were favorable for severe infection of maize plants with the pathogen.Results and conclusion. No disease symptoms were found in 173 accessions; 162 genotypes were affected only slightly. The greatest number of accessions with resistance to boil smut belonged to subsp. indentata (Sturt.) Zhuk. (69.4% of the total studied accessions), subsp. everta (69.2%) and subsp. semidentata (Sturt.) Zhuk. (66.7%). Accessions of subsp. amylacea (Sturt.) Zhuk. were more susceptible to the pathogen than other maize subspecies. The Russian, European and North American local maize varieties and self-pollinated lines had a low infection rate, while the accessions that came to the VIR collection from Asia and South America showed higher rates. After two years of comprehensive studies, the selected forms can be recommended for the use in breeding for immunity.

Представители родовых комплексов Robinia (Робиния), Gleditsia (Гледичия) относятся к экономически важным и перспективным, для деградированных ландшафтов засушливого региона, видам растений. Несмотря на это до последнего времени отсутствуют сведения по многим видам этих родовых комплексов, связанные с вопросами экологических основ семеноведения и их репродуктивной способности в условиях светлокаштановых почв Волгоградской области. Все это направлено на выявление и расширение перспективных ареалов культивирования для лесомелиорации и озеленения населенных пунктов. Цель исследований изучение репродуктивной способности представителей родовых комплексов Robinia (Робиния), Gleditsia (Гледичия) в коллекциях ФНЦ агроэкологии РАН и выявление особенностей их селекционного семеноведения для лесомелиорации и озеленения населенных пунктов в сухостепных условиях. Объектами исследований являлись виды и формы рода Robinia: R. viscosa Vent. R. neomexicana Gray. R. pseudoacacia L. R. neomexicana х pseudoacacia, и Gleditsia (G. triacanthos L., G. triacanthos L. f. inermis, G. caspica Desf, G. texana Sarg., G. aquatica, G. japonica, G. caspica, G. sinensis), произрастающие в кластерных участках коллекций ФНЦ агроэкологии РАН, кадастр 34:34:000000:122, 34:34:060061:10. Разработка основ селекционного семеноведения базируется на изучении репродуктивных особенностей выделенных для целевого использования собственных биоресурсов с учетом возможностей всестороннего изучения генеративных качеств и оценки биологического потенциала. Выявлено, что стабильность плодоношения фиксируется через несколько лет после вступления в генеративную фазу: у Robinia и Gleditsia 67 лет. Первое цветение у Gleditsia triacanthos и G. texana, G. aquatica наблюдалось в возрасте 5 лет, G. japonica 6, G. caspica и G. sinensis 8 лет. Завязываемость плодов зависит не только от возраста растения, но и от погодных условий во время цветения. На семенную продуктивность влияет количество выпавших осадков и сумма активных температур в период созревания плодов. Формирование более крупных плодов и семян наблюдается в возрасте до 15 лет. В результате исследований (20172019 гг.) выявлено влияние лимитирующих факторов на биологический потенциал цветения, плодоношения и семенную продуктивность для определения ареалов их культивирования. Representatives of generic systems Robinia, Gleditsia are economically important and promising for degraded arid landscapes of the region, types of plants. Despite this, until recently, there is no information on many types of these generic complexes related to the environmental foundations of seed and their reproductive capacity in light chestnut soils of the Volgograd region. All this is aimed at identifying and expanding promising areas of cultivation for forest reclamation and greening of settlements. The aim of the research is to study the reproductive capacity of representatives of ancestral complexes Robinia, Gleditsia in the collections of the Federal scientific center for Agroecology Russian Academy of Sciences and the identifying features of their selection of seed for forest reclamation and landscaping of settlements in the dry steppe conditions. The objects of research were species and forms of the genus Robinia: R. viscosa Vent. R. neomexicana Gray. R. pseudoacacia L. R. neomexicana x pseudoacacia and Gleditsia (G. triacanthos L., G. triacanthos L. f. inermis, G. caspica Desf, G. texana Sarg., G. aquatica, G. japonica, G. caspica, G. sinensis), growing in the cluster areas of collections of FSC Agroecology RAS, cadastre 34:34:000000:122, 34:34:060061:10. The development of the principles of seed breeding is based on the study of reproductive characteristics of the allocated for the targeted use of their own bioresources, taking into account the possibilities of a comprehensive study of generative qualities and assessment of biological potential. It was found that the stability of fruiting is fixed a few years after entering the generative phase: Robinia and Gleditsia 67 years. The first flowering in Gleditsia triacanthos and G. texana, G. aquatica was observed at the age of 5 years, G. japonica 6, G. caspica and G. sinensis 8 years. Fruit setability depends not only on the age of the plant, but also on weather conditions during flowering. Seed productivity is affected by the amount of precipitation and the amount of active temperatures during the ripening period. The formation of larger fruits and seeds is observed in the age of 15 years. As a result of studies (20172019), the influence of limiting factors on the biological potential of flowering, fruiting and seed production to determine the areas of their cultivation was revealed.

The article presents the results of the analysis of the biochemical composition of selected in the competitive variety testing of new varieties and promising lines of spring barley, studied on the experimental field ISA-branch of FGBNU FNAC VIM in 2016-2018. Result of research in different years of water availability among the rooms was allocated a group of high-protein barley with improved feed value: 4 varieties, 2 of which are on the state variety testing, and 2 promising lines. The range of variation of protein content in the grain of the selected samples varied from 13.1 to 14.5 %, lysine – from 0.48 to 0.52 %, weight of 1000 grains-from 48.0 to 53.5 g. According to the data obtained the highest value of protein in grain was observed in krupnosortnogo varieties Zlatoyar (GSI), amounting on average for 14.5 %. The increase was equal to 1.1% in relation to the control variety Yaromir. With an average yield of 6.52 t/ha in the years of research grade Accounting have provided protein per hectare in the amount of 0,94 t/ha. A new variety Sudar´ (GSI) and breeding line 149/4-12 h 788 and 129/1-14 h 907 this indicator has been less productive, however, exceeded the grade Yaromir 0.10 to 0.16 t/ha. Given the higher productivity of new promising varieties and breeding lines, the collection of lysine per unit area they have 12.7, 30.8 per cent was higher than that of the Promej class and 10.6-23.6% more than in the variety Yaromir, which indicates their high biological value. Selected hulless line 1137 h is also an encouraging source of protein and other nutrients of plant origin. The selected lines and new varieties, regardless of weather conditions, were able to ensure the production of high-protein and sources' grain for feed purposes, while maintaining productivity.

This paper presents an approach for retrieval of soil moisture content (SMC) by coupling single polarization C-band synthetic aperture radar (SAR) and optical data at the plot scale in vegetated areas. The study was carried out at five different sites with dominant vegetation cover located in Kenya. In the initial stage of the process, different features are extracted from single polarization mode (VV polarization) SAR and optical data. Subsequently, proper selection of the relevant features is conducted on the extracted features. An advanced state-of-the-art machine learning regression approach, the support vector regression (SVR) technique, is used to retrieve soil moisture. This paper takes a new look at soil moisture retrieval in vegetated areas considering the needs of practical applications. In this context, we tried to work at the object level instead of the pixel level. Accordingly, a group of pixels (an image object) represents the reality of the land cover at the plot scale. Three approaches, a pixel-based approach, an object-based approach, and a combination of pixel- and object-based approaches, were used to estimate soil moisture. The results show that the combined approach outperforms the other approaches in terms of estimation accuracy (4.94% and 0.89 compared to 6.41% and 0.62 in terms of root mean square error (RMSE) and R2), flexibility on retrieving the level of soil moisture, and better quality of visual representation of the SMC map.

Aims. We aim to evaluate the near-infrared colors of brown dwarfs as observed with four major infrared imaging space observatories: the Hubble Space Telescope (HST), the James Webb Space Telescope (JWST), the Euclid mission, and the WFIRST telescope. Methods. We used the SPLAT SPEX/ISPEX spectroscopic library to map out the colors of the M-, L-, and T-type dwarfs. We have identified which color–color combination is optimal for identifying broad type and which single color is optimal to then identify the subtype (e.g., T0-9). We evaluated each observatory separately as well as the narrow-field (HST and JWST) and wide-field (Euclid and WFIRST) combinations. Results. The Euclid filters perform equally well as HST wide filters in discriminating between broad types of brown dwarfs. WFIRST performs similarly well, despite a wider selection of filters. However, subtyping with any combination of Euclid and WFIRST observations remains uncertain due to the lack of medium, or narrow-band filters. We argue that a medium band added to the WFIRST filter selection would greatly improve its ability to preselect brown dwarfs its imaging surveys. Conclusions. The HST filters used in high-redshift searches are close to optimal to identify broad stellar type. However, the addition of F127M to the commonly used broad filter sets would allow for unambiguous subtyping. An improvement over HST is one of two broad and medium filter combinations on JWST: pairing F140M with either F150W or F162M discriminates very well between subtypes.

In addition to calculating the comfort score using the TCI and HCI methods and modifying their thermal aspects, a survey was also carried out in all three tourism areas simultaneously. The survey was conducted to collect data on climate comfort perceptions and the role of the weather on these comfort. A total of 793 respondents participated in this study. The majority of visitors stated that the weather affected the comfort of the climate during the tour. But weather conditions do not fully influence decisions in the selection of tourist visits. The level of perceived climate comfort for the three tourism sites namely Ecopark was perceived as neutral (57.3%), KRB was perceived as comfortable (60%) and KRC was perceived as comfortable (78.4%). While based on the score calculation approaching the survey results in Ecopark is TCI index modified in its thermal aspect with PET Tianjin (57.2). KRB is HCI without modification (59) and KRC is HCI modified by its thermal aspect with PET Tianjin (77.6). Statistically there are significant differences between sex, age, education level and topography. By understanding visitor perceptions, strategies and appropriate actions can be developed to increase comfort in the nature-based tourism industry.
