The problem to develop new early maturing grain sorghum varieties adapted to mechanized harvesting with high productivity and feed advantages, is of great urgency. The purpose of the current work was to study the inheritance of the main economically valuable traits in the first generation hybrids developed in the hybridization between samples of different ecological and geographical origin. In the first generation hybrids Zernogradskoe 88 × Seso 1 and Zernogradskoe 88 × Narosorg 1, there was identified the improvement of 1000-grain weight, number of grains per panicle, and length of a peduncle in comparison with the initial parental forms. In the hybrid combination obtained as a result of hybridization of the varieties Zernogradskoe 88 and Seso 3 there was not identified any positive manifestation of heterosis for the breeding process in the main studied traits. According to the trait ‘plant height’ in all combinations, there was identified overdominance of high-growing forms. According to the protein percentage in grains there was established depression or dominance of lower values of the trait. The inheritance of the trait ‘length of vegetation period’ in the studied hybrids corresponded to the partial dominance of both lower and higher values of the trait.

Pea (Pisum sativum L.) is a widespread leguminous crop. It is used for food purposes, as well as concentrated high-protein feed  for  farm animals.  In addition  to a great nutrition value, a balanced amino acid composition and an excellent  taste,  it  is peas that is capable to produce large grain yields even in the risky arable zone, which most of the territory of our country belongs to. The development of the new high-protein, productive pea varieties that most fully realize the soil-climatic potential and meet the requirements of agricultural production is an urgent concern of breeders. The purpose of the current study was to develop a new pea variety, adapted for cultivation in the Republic of Bashkortostan. There has been estimated the collection peas material on morphobiological and economically valuable traits. The best varieties have been used for hybridization. Among the hybridized breeding forms there has been identifed the line “L-31315/14” which possesses economically valuable traits. In 2019, this line was sent to the State Variety Testing as the variety “Pamyati Popova”. The new variety was bred by multiple individual selection from a hybrid population “K-7992” (Korea) × “Barbel”. The variety “Pamyati Popova” is a middle ripening variety with 64–78 days of vegetation period. The kernels contain 20.7–22.4% of protein. The variety is of good taste and cooking properties. Its disease and pests’ resistance is similar to that of the standard variety. According to the Competitive Variety Testing, the average yield increase of the variety “Pamyati Popova” was on 3.9 hwt/ha in 2016–2019. The largest kernel yield of the variety was 26.9 hwt/ha in 2017.

In 2016-2018 in the competitive variety testing there was conducted the study of peas on the fields of research crop rotation of the laboratory of legumes breeding and seed-growing of the FSBSI “ARC “Donskoy” located in the zone of unstable humidity of the Rostov region (Zernograd district). The analysis of the obtained seeds was carried out in the laboratory of biochemical estimation of breeding material and grain quality of the FSBSI “ARC “Donskoy”. The objects of research were new pea lines of breeding of the FSBSI “ARC “Donskoy”, which differed in their morphological, biological and economically valuable traits and properties. During the years of research, the meteorological conditions of the vegetation period of peas were contrasting, which made it possible to objectively estimate the lines in the climatic conditions. In the competitive variety testing for the period of 2016-2018, the evaluation of new promising pea lines due to their productivity and protein percentage resulted in identification the leafless pea lines “G-1002” and “G-1003” which exceeded the standard variety “Aksaisky Usaty 5” in productivity (0.30 and 0.39 t/ha) and protein yield (0.08 and 0.10 t/ha, respectively). There is a high correlation between seed productivity and protein content (0.95). There is a low correlation between protein percentage in seeds and protein yield (0.35). There is no correlation between productivity and protein percentage in seeds (0.03). The analysis of correlations shows that pea breeding on productivity directly affects on protein yield, i. e. the larger seed productivity, the larger protein percentage. The most productive pea lines are going to be used in further breeding work.

Rice is a valuable agricultural crop that is used as food for more than half of the world's population. The development of highly productive varieties and hybrids with high product quality assumes the utilization of new initial material from different countries in the breeding process. The purpose of the current research was to conduct an ecological testing of the rice varieties from Uganda in the Proletarsky district of the Rostov region in Russia and use them in the breeding process. There were studied the Ugandan rice samples ‘Nerica 1’, ‘Nerica 4’, ‘Komboka’, ‘Wita 9’, ‘Namche 1’, ‘Namche 2’, ‘Namche 3’, ‘Namche 4’, ‘Namche 5’, ‘Namche 6’ (NaCRRI) in comparison with the Russian variety ‘Komandor’ (FSBSI “ARC “Donskoy”). The study of the Ugandan rice varieties according to a number of economically valuable traits and biological properties showed that the vegetation period from soil flooding to rice maturing took 100–113 days, the standard variety ‘Komandor’ needed 83 days. The varieties ‘Komboka’ and ‘Wita 9’ did not bear blossom. All samples had a short habit, with 63-95 cm of plant height. The long drooping panicles of 18.5–22.3 cm carried from 122 to 213 seeds. The caryopses were elongated, the length of the caryopses varied from 9.0 to 9.5 mm, and the width ranged from 2.7 to 3.1 mm. 1000 seed weight varied from 26 to 34 g, number of seeds per panicle ranged from 122 to 213 pieces. Genetic analysis of the second generation hybrids ‘Kontakt × Nerica 1’ and ‘Boyarin × Nerica 4’ showed different types of traits’ inheritance, from negative dominance (vegetation period) through the absence of dominance (caryopses size) to overdominance (plant height, seed weight per panicle and number of seeds per panicle).

The aim of the research was to expand the genetic diversity of winter triticale samples by intraspecific hybridization and to obtain new valuable forms for their involvement in the selection process of creating high-yielding cultivars. The research was conducted during 2013–2020 at the sites of the Department of Genetics, Plant Breeding and Biotechnology of Uman National University of Horticulture, Ministry of Education and Science of Ukraine. As initial material for hybridization was used samples of hexaploid triticale of own breeding and varieties Rozivska 6, Ladne, Khlibodar Kharkivsky, Beta, Alkid, Souvenir, Raritet; octaploid triticale samples UA0602463 and UA0601654. Hybrid offspring were analyzed for morphological and economically valuable traits, including plant height, lodging resistance, ear length, grain weight from the main ear and 1000 grains, protein and gluten content in the grain and its quality indicators, yield, etc. In the studies used a systematic method of site placement. The rooms were arranged in blocks with a plant density of 400 thousand units/ha four times. In the course of researches hybridization of hexaploid forms of triticale of different ecological and geographical origin among themselves, and also hybridization of octaploid forms with hexaploid was carried out. In F2 populations, individual-family selection of low-stem forms with high ear grain was performed. In the absence of low-stem forms in the area of F2 hybrids, ear productivity was selected, and the population was transferred to a hybridization nursery for crossing plants with donors of low-stem genes. As a result of the conducted researches 23 highly productive forms of winter triticale were obtained, in particular, two dwarf samples (h = 58 cm), four – short-stemmed (h = 60–80 cm), one – early-ripening (vegetation period 285 days), nine – with high ear productivity. Sample 63 was selected, which significantly exceeded the group standard in terms of yield (7.01 t/ha), protein content (12.2 %) and gluten of the first quality group (25.4 %).

Goal. To establish correlations between the seed weight and quantitative characteristics of performance for new introduced soybean accessions.Results and discussion. The results of evaluating the following introduced accessions for a set of economically valuable traits are presented in the article: Saska, 01006; Sigalia, 01020 (AUT) Connor, 00549; Sandra, 00679; Madison, 01011; OAC Drayton, 01014; OAC Wallace, 01018; Kyoto, 01012; Silesiya 01010 (CAN) Cordoba, 01020; Lissabon, 01007 (AUS) Sultana, 01008; Sinara, 01005 (FRA). Among all the accessions under investigation, variety Silesiya 01010 (CAN) was distinguished by ultra-early ripening. The duration of its vegetation period was 98 days. The results of studying the introduced accessions allowed us to single out a source, variety Sultana, 01008 (FRA), by exceptionally high performance, as its seed weight per plant was 39.4 g or the seed number per plant was 230.0. There were correlations between the main trait of the plant performance, the seed weight per plant, and the traits of "productive node number per branch", "productive node number per plant", "pod number per branch," "pod number per plant", and "seed number per plant" in soybean varieties (Kyoto, 01012 (CAN) Sinara, 01005, Sultana, 01008 (FRA) and Cordoba, 01020 (AUS), which had the best yields. It was established that genotypes could be selected by these traits to form a variety model.Conclusions. Basing on the correlations, we found that the plant height, the lowest pod height, the productive node number per branch, the additional branch number per plant, the pod number per plant, and the seed number per plant had the most significant direct effects on the variability of the main performance trait - the seed weight per plant.

Background: In recent years, large areas are periodically exposed to drought due to the climate change towards warming. In this regard, there is a need to expand the area of cultivation of drought-resistant leguminous crops. One of these species of interest for cultivation in the central lowlands of the Republic of Azerbaijan, where bean crops are greatly suppressed, is vigna. To date, this culture is not widespread, its biological and energy potential is underestimated. Therefore, the study of morphological and biological characteristics of promising varieties of cowpea in the region and a comprehensive study of the genetic resources of the culture is relevant. The purpose of the research is to study the cowpea collection, to identify forms with economically valuable traits and to create on their basis a new highly productive, technologically advanced, valuable with its quality vigna grain for a selection in the conditions of the Republic of Azerbaijan.Methods: The studies were conducted in 2007-2018 at the Institute of Genetic Resources (IGR) of the National Academy of Sciences (NAS) of Azerbaijan. 33 samples were used as research material: 9 of them were local forms and 24 were samples obtained from VIR. The vegetation period and resistance to diseases have been studied and the productivity and structure of the harvest have been analyzed. Result: As a result of research, the most high-yielding and high-quality samples K-269, K-257, AzeVÝG-2, K-271, K-262, AG-340 were revealed in the studied vigna samples. During the implementation of the breeding program using the results, we have developed a new early ripe, drought-resistant, heat-resistant, disease-resistant and high-yielding variety Ayla by the method of repeated individual selection from the VIR collection. These studies are an important initial study for the subsequent production of new varieties. We hope that this will lead to an increase in the acreage of cowpea in the Republic of Azerbaijan.

The purpose of the current study was to identify the effect of the length of a vegetation period of the collection soybean samples on grain productivity and quality. The study was carried out in the southern part of the Rostov region in the fields of the FSBSI Agricultural Research Center “Donskoy” in 2018–2020. The climate is semi-arid with moderately hot summers. The soil is ordinary thick calcareous heavy loamy blackearth (chernozem). The forecrop was winter wheat. The objects of the study were collection soybean samples of the ARIGPR named after N.I. Vavilov. The study was carried out on 75 samples, including 52 middle early samples with 110-120 days of vegetation and 23 middle maturing samples (120-130 days of vegetation), differing in morphobiological and economically valuable traits. The analysis of a vegetation period, grain productivity and quality of the collection soybean samples has shown that in the southern part of the Rostov region the most variable trait was grain productivity (Cv = 22.5%). The less variable characteristics were protein percentage in grain (Cv = 3.8%), a vegetation period (Cv = 4.2%) and oil content in grain (Cv = 5.3%). There has been identified a positive effect of the length of a vegetation period of soybeans on grain productivity and oil content in grain for both groups of maturity, protein percentage in both groups of maturity having a negative dependence on a vegetation period. The study has shown that in the middle early group, the largest grain productivity was obtained with 117 and 118 days of vegetation, the highest protein percentage with 110 and 114 days of vegetation, and the largest oil content in grain with 118 and 120 days of vegetation. In the middle maturing group, the maximum productivity indicators were obtained for the samples with 126 and 130 days of vegetation, the maximum protein percentage with 122 days of vegetation and the maximum oil content in grain with 123 and 130 days of vegetation. The samples showing the maximum indicators will be included in further soybean breeding.

For creating new cultivars of red clover it is necessary to use traditional and modern methods: polyploidy, mutagenesis, heterosis and ecological breeding. These methods have been used in breeding for a long time, but it was necessary to modify them to the cultivation of red clover considering its biological fea-tures (perennity, length of vegetation period, winter hardiness) in conditions of harsh continental climate in Siberia. The complex-hybrid population, late maturing, diploid based – the cultivar SibNIIK 10 has been created based on best polycross offspring by polycross method in West Siberia. The winter hardy, early maturing, tetraploid based cultivar Meteor has been created as the result of combination of mutage-nesis, polyploidy, hybridization and selection methods together with FWRC FPA for the first time ever in Siberia. The research cites a comparative study of two cultivars of red clover (SibNIIK 10 and Meteor) of different types of maturity and ploidy by main economically valuable traits. Early maturing tetraploid based cultivar Meteor in herbage and dry matter yield exceeds late maturing cultivar SibNIIK 10 by 9–39 and 7–41% and in seed yield SibNIIK 10 exceeds Meteor by 30%.
