One of the major challenges facing the selection of leguminous crops, and pea in particular, is to increase their technological properties and yield. An important problem is also the increase of protein content in the seeds. The aim of this work was to create a high-tech variety of field peas with a short growing period. By repeated individual selection from the hybrid population of the Chishminsky 95 × Usach field pea, a precocious, highly productive PamyatiHangildina variety of pea (leafless) was obtained. The combination of new mutant traits in one plant (seed shedding - def gene, leafless type - af gene) and elements of productivity structure with optimal level of their development allowed the variety to successfully pass all tests and in 2012 it was included in the State Register of Selection Achievements of the Russian Federation . For an average of 5 years of competitive testing, the variety had a seed yield of 1.62 t/ha, exceeding the standard (control) by 0.67 t/ha. The created variety has a short growing period and a high content of protein in the seeds. The research results could be successfully used in the selection of improved peas.

The paper presents the results of research into breeding of the new cultivar of oil radish Sibiryachka by the method of multiple individual selection during the period 2008-2018. The cultivar of oil radish Tambovchanka was used as an initial material. The studies were conducted in the foreststeppe zone of Western Siberia (Novosibirsk region) in the breeding nurseries laid on fallow by a widerowed method. Well-developed plants were selected in the field conditions, which were then used for selection of the most productive forms for further sowing, on the basis of the thorough laboratory analysis of the components of the seed yield. For comparative analysis the initial standard cultivar Tambovchanka was used. The main attention in the selections process was paid to high seed and feed productivity, early maturity, resistance to main diseases and pests. As a result, after conducting five selection cycles, a complex hybrid population was obtained, which, in the contest trial during three years, showed an advantage over the standard cultivar by seed and dry matter yield, as well as by stability of seed yield. It was submitted for the state cultivar test with the name Sibiraychka. The main economically valuable features of the oil radish cultivar Sibiryachka are as follows: the average yield of green mass is 33.6 tn/ha, seeds – 1.2 tn/ ha, the seed protein content is 28%. The cultivar is early-ripening, so the duration of the growing season is 89-101 days. It reaches mowing ripeness in 59-75 days. The leaf formation of the cultivar is 41-59%. The new cultivar is resistant to major diseases and pests and is intended for fodder and green manure use. The cultivar was included in the State register of breeding achievements suitable for cultivation on the whole territory of the Russian Federation in 2018. The copyright certificate and patent were received.

Field pea seeds from 10 cultivars grown at two locations in Manitoba in 1986 and 1987 were analyzed for proximate and mineral profiles. Cultivars differed significantly in their level of total protein, crude fat, ADF, and all minerals tested. However, differences were not extremely large and were comparable to European reports. Location-year also had a significant effect on the levels of total protein, ADF, and all minerals tested. In most cases, the warmest location-year produced relatively higher levels of minerals, ash, and total protein, and lower seed yield than the coolest location-year.

Рассмотрены важные аспекты использования геноносителей различных маркерных признаков при создании и селекции гетерозисных гибридов томата для защищенного грунта. Наряду с общими требованиями к родительским компонентам, касающимися продуктивности растений, скороспелости, устойчивости к болезням и т. д., сегодня при селекции на гетерозис для защищенного грунта к исходному материалу предъявляют более высокие требования по наличию хозяйственно полезных признаков. Эти требования касаются типа роста растений, формы, окраски и качества плодов, типа кисти, формы плодоножки и т. д. Представлены характеристики исходного материала для создания гетерозисных гибридов томата, а также даны характеристики полученных гибридов. Исследования, проведенные в отделе селекции ВНИИО (ВНИИ овощеводства – филиал ФГБНУ ФНЦО), показали большую перспективность использования при гетерозисной селекции томата для защищенного грунта геноносителей различных маркерных признаков, особенно признаков, определяющих коричневую окраску эндосперма семян (гены bs и bs-2) и несочлененную плодоножку (ген j-2). Созданные с использованием этих маркерных признаков гибриды и селекционные линии по-своему уникальны и являются приоритетным достижением этого научного учреждения, так как они представляют большой интерес для гетерозисной селекции томата в качестве исходного материала. Целый ряд гибридов F1 включен в Госреестр селекционных достижений, допущенных к использованию (Удача, Голубчик, Клад овощевода, Заур и др.). В связи с развитием фермерского и любительского овощеводства в последние годы определенное внимание было уделено созданию новых мутантных линий с розовыми, малиновыми и темно-коричневыми плодами с высокими вкусовыми качествами (учитывая, что образцы такого типа пользуются повышенным спросом у населения и стоят дороже). При создании новых гетерозисных гибридов были учтены эти признаки родительских форм. Important aspects of the use of gene carriers of various marker traits in the creation and selection of heterotic tomato hybrids for greenhouse industry are considered. Along with the general requirements for the parent components concerning plant productivity, precocity, resistance to diseases, etc., today, when breeding for heterosis for greenhouse industry, higher requirements are imposed on the source material for the presence of economically useful features. These requirements relate to the type of plant growth, shape, colour and quality of fruits, brush type, stem shape, etc. The characteristics of the initial material for creating heterotic tomato hybrids are presented, as well as the characteristics of the resulting hybrids are given. Studies conducted in the breeding department of the ARRIVG (ARRIVG – a branch of the FSBI FSCV) showed great prospects for the use of gene carriers of various marker traits, especially those that determine the brown colour of the seed endosperm (bs and bs-2 genes) and an undifferentiated peduncle (j-2 gene) in the heterosis breeding of tomatoes for greenhouses. Hybrids and breeding lines created using these marker traits are unique in their own way and are a priority achievement of this scientific institution, since they are of great interest for the heterosis breeding of tomato as a basic material. A number of F1 hybrids are included in the State Register of Breeding Achievements allowed for use (Udacha, Golubchik, Klad ovoschevoda, Zaur, etc.). Due to the development of farming and amateur vegetable growing in recent years, some attention has been paid to the creation of new mutant lines with pink, crimson and dark brown fruits with high taste qualities (given that samples of this type are in high demand among the population and are more expensive). When creating new heterotic hybrids, these features of the parent forms were taken into account.

Abstract In Uruguay, reforestations with Eucalyptus sp. is of fundamental importance to supply paper, pulp, and wood production. This study investigates genetic, productivity, stability, and adaptability parameters in the selection of Eucalypts grandis x Eucalyptus globulus full-sib hybrid clones. The study was conducted in a clonal test, repeated in two different soils types, in Rio Negro State, Uruguay. The population was characterized phenotypically for diameter at breast height (dbh) and genotyped for SNP markers (EuCHIP60K chip). Mean dbh was similar between sites and the genotype–environment interaction was simple. We found high genotype correlation in clone performance between environments (0.708), indicating the possibility of selecting the same clones for both study locations. Mean heritability between clones (0.724), coefficient of individual genetic variation (10.9 %), and relative variation (0.916), suggest the possibility of gains (estimated at 3.1 % for both sites together) by selecting clones with higher growth rates. A total of 15,196 SNPs were used to confirm parentage and test a genomic selection model for dbh. The predictive capacity was negative (-0.15) given the small population size (78 individuals). The most adaptable material among the tested study sites presented higher values for SNP heterozygosity. Thus, using molecular markers to identify clones responsive to environmental changes can act as a powerful tool in Eucalyptus breeding programs. The hybrid population showed greater adaptability than E. globulus for this region.

The agrotechnical significance of leguminous crops, in particular soybeans, consists in its ability to provide a huge bulk of vegetable protein and less nitrogen depletion of soils than non-legume crops [2]. Despite the fact that nitrogen symbiotically fixed by soybean plants is alienated with the harvest and taken out of the field with organic residues of leguminous crops, more nitrogen remains in the soil after them than with residues of other crops. In this regard soybeans are good predecessors in various stages of crop rotation. The article discusses topical issues of increasing productivity of leguminous crops, in particular, soybeans, when using different doses of ammophos against the background of its placement in various ways of main tillage of drained leached chernozems. In 2018–2019 studies were carried out to establish the influence of the optimal dose of mineral nutrition and the best method of soil cultivation on the productivity and quality indicators of soybeans of the French selection of the Amphora, Mentor and Isidor varieties. According to the results of the research, different effectiveness of the considered variants of the experiment was established. Thus, higher rates of soybean yield were noted in the later-maturing Isidor variety within 2,03–2,30 t/ha for plowing, and 1,70–1,91 for soil disking. The most cost-effective dose of mineral nutrition for all studied soybean varieties was the dose of 50 kg/ha of Ammophos (N6H26) against the background of plowing, where the profit from the increase in yield relative to the control was in the range of 2900–3650 rubles/ha, and against the background of disking soil the dose of Ammophos was 100 kg/ha (N12H52), where the profit was in the range of 1300–2050 rubles/ha.
