The narrow-leafed lupine (Lupinus angustifolius L.) has long been used as a green manure crop. Alkaloid content which is incompatible with forage varieties is a desirable trait for green manure ones. Alkaloids presented in plowed biomass of the green manure lupine have disinfected action for soil resulted in the lower infection of the next crops. The undemanding nature of green manure lupine to growing conditions consists of several features: it is an active nitrogen accumulator and provides 70 % of nitrogen for own needs, and its deeply penetrated root system allows make up the deficit of nutritional substances in arable layer with use of sub-soil horizons. The aim of the study was to reveal perspective narrow-leafed lupine’s green manure varieties and breeding lines for grain and green mass yield, for length of the vegetation season, alkaloid content and other morphological and biological characters. The tests have been done under Bryansk region’s conditions (the South-West zone of the Central region of Russia) on soddy-podzolic loamy cultivated soils with the moderate fertility level. The objects of the research were seven green manure varieties and breeding lines of the narrow-leafed lupine which have been tested in competition tests of 2021-2022. The breeding line Siderat 265-19 stand out for grain (2.62 t/ha), green mass (31.9 t/ha) yield and for early maturing (84 days). Alkaloid content in its seeds made 1.003 %, the standard level. The article presents the results of structural analyses for morphological peculiarities and productivity elements of new green manure hybrid lines (the standard variety – Tshutchinskiy).). The No. 1764 (Siderat 46 x Kormovoy 344) had the best index for plant height. The No. 1749 (Siderat 46 x Bryanskiy siderat) picked out for grain productivity. The seed weight per a plant was 14.3 g and the pod’s seedingwas 5.2 seeds.

“…Soybean is cultivated in a wide range of latitudes from 55° north to 35° south. However, the area of cultivation of each cultivar is limited to a very narrow range of latitudes and usually there is one cultivar per 1° of latitude (Agarkova et al, 2016). This is due to a strong reaction to the photoperiod.…”

Development of a marker panel for genotyping of domestic soybean cultivars for genes controlling the duration of vegetation and response to photoperiod

Soybean, Glycine max L., is one of the most important agricultural crops grown in a wide range of latitude. In this regard, in soybean breeding, it is necessary to pay attention to the set of genes that control the transition to the flowering stage, which will make it possible to adapt genotypes to local growing conditions as accurately as possible. The possibilities of soybean breeding for this trait have now significantly expanded due to identification of the main genes (E1–E4, GmFT2a, GmFT5a) that control the processes of flowering and maturation in soybean, depending on the day length. The aim of this work was to develop a panel of markers for these genes, which could be used for a rapid and efficient genotyping of domestic soybean cultivars and selection of plant material based on sensitivity to photoperiod and the duration of vegetation. Combinations of 10 primers, both previously developed and our own, were tested to identify different alleles of the E1–E4, GmFT2a, and GmFT5a genes using 10 soybean cultivars from different maturity groups. As a result, 5 combinations of dominant and recessive alleles for the E1–E4 genes were identified: (1) e1-nl(e1-as)/ e2-ns/e3-tr(e3-fs)/e4; (2) e1-as/e2-ns/e3-tr/E4; (3) e1-as/e2-ns/E3-Ha/e4; (4) E1/e2-ns/e3-tr/E4; (5) e1-nl/e2-ns/E3-Ha/E4. The studied cultivars contained the most common alleles of the GmFT2a and GmFT5a genes, with the exception of the ‘Cassidi’ cultivar having a rare dominant allele GmFT5a-H4. The degree of earliness of cultivars positively correlated with the number of recessive genes E1–E4, which is consistent with the data of foreign authors on different sets of cultivars from Japan and North China. Thus, the developed panel of markers can

Background. Abiotic stressors, such as prolonged dry conditions, oversupply or lack of moisture, frost, etc., are spontaneous, and their impact causes significant damage to plants. This is also true for the common and leafless morphotypes of vegetable pea, which are most widely used in large-scale crop production.Objectives. Eleven cultivars with leaves of the usual type (common morphotype) and 6 semi-leafless ones (leafless morphotype) were studied.Materials and methods. The experiments were performed on the breeding fields of Krymsk Experiment Breeding Station of VIR (Krasnodar Territory, 2015–2016). The plot area was 10 m2. There were 3 replications. Dry matter content was measured by drying the aerial parts of plants (axial organs, foliar apparatus [leaf, stipules], flowers, unripe beans, pod valves, grain) to constant dry matter at 105°C. Dry matter contents were compared using the t-test. Multifactorial analysis of variance (MANOVA, LSD test) was used to assess the yield of vegetable pea cultivars.Results. Vegetable pea plants are subject to the negative effect of abiotic stressors. With excessive moisture in the initial period of growth, there was a decrease in the accumulation of dry matter in plants. A similar effect is exerted by long absence of precipitation during the growth period of vegetable pea plants from the phase of 2–3 leaves to technical ripeness. The effect of weather conditions during cultivation on the yield of vegetable peas was estimated at 13.3%; and the interaction of the genotype٭environment factors, at 33.3%.Conclusion. No significant differences were observed between the groups of common leafy cultivars and semi-leafless ones in the content of dry matter in the aboveground biomass of plants and the yield. During the two years of research, the cultivars that exceeded the reference in yield were identified: ‘Prima’ (i-155213, Russia) and ‘Ambassador’ (k-9946, Germany), both belonging to the common morphotype.
