Variety of narrow-leaved lupine (<i>Lupinus angustifolius L.</i>) Mezenat

The purpose of the study was to create of an early ripening variety of narrow-leaved lupine with a seed and green mass yield above the standard, resistant to unfavorable biotic and abiotic environmental factors in the North-West region of the Russian Federation. As the result of many years of breeding, an early ripening variety of narrow-leaved lupine Metsenat has been developed. In a competitive varietal trial conducted in the conditions of the Leningrad Region, the seed yield of the variety Metsenat averaged 4.3 t/ha in 2015-2017 that was 1.1 t/ha higher than the standard (Kristall), the yield of green hay was 48.4 t/ha (13.9 t/ha higher than the standard). According to the results of the structural analysis of plants, the variety Metsenat was characterized by an increased number of seeds per plant (90.4 pcs.) and a good seeding of the beans (4.4 pcs.). It is a variety of universal use, with a low content of alkaloids (0.0072 %), it is technological, resistant to lodging (7 points), to cracking of beans and shedding of seeds on the vine, resistant to anthracnose (9 points). It is characterized by a rapid growth rate of plants in the initial period of vegetation. In 2018 the Metsenat variety was included into the State Register of Breeding Achievements of the Russian Federation approved for use in agricultural production in 12 regions (Patent No. 9559)

Rapid ecological change in the coastal zone of Lake Baikal (East Siberia): Is the site of the world\u27s greatest freshwater biodiversity in danger?

Ecological degradation of the benthic littoral zone is an emerging, urgent problem at Lake Baikal (East Siberia), the most species-rich lake on Earth. Within the last five years, multiple changes have occurred in the nearshore benthos where most of the lake\u27s endemic species reside. These changes include proliferation of benthic algae, deaths of snails and endemic sponges, large coastal wash-ups of dead benthic algae and macrophytes, blooms of toxin-producing benthic cyanobacteria, and inputs of industrial contaminants into parts of the lake. Some changes, such as massive coastal accumulations of benthic algae, are currently shared with the Laurentian Great Lakes (LGLs); however, the drivers of these changes differ between Lake Baikal and the LGLs. Coastal eutrophication from inputs of untreated sewage is causing problems at multiple sites in Lake Baikal, whereas in the LGLs, invasive dreissenid mussels redirect pelagic nutrients to the littoral substrate. At other locations in Lake Baikal, ecological degradation may have different causes including water level fluctuations and the input of toxic industrial contaminants. Importantly, the recent deterioration of the benthic littoral zone in both Lake Baikal and the LGLs has occurred while little change has occurred offshore. This highlights the necessity of monitoring both the littoral and pelagic zones of large lakes for assessing ecosystem health, change and conservation

New varieties of winter rye of intensive type

The work of breeders of the Leningrad Research Institute of Agriculture Belogorka on the creation of new short-stature varieties of intensive type winter rye, characterized by increased resistance to adverse soil and climatic conditions of northern Europe is briefly described. The methods of selection used in the institute are presented, including the method of directed transpollination of crops “on a flower bed” developed in the winter rye laboratory. The characteristic of new varieties based on economic and useful features and on the main elements of the crop structure is given. It was shown that the new varieties significantly exceeded the standard Volkova variety in winter and lodging resistance, which allows obtaining a stable grain harvest even in unfavorable years. In addition, new varieties are characterized by the size and uniformity of seeds at the weight of 1000 grains 38–42 g, practically not inferior in this indicator to tetraploid and hybrid varieties of winter rye, which are more demanding of cultivation conditions

EFFICIENCY OF RAW GLUTEN CONTENT PREDICTION IN WHEAT KERNELS

The conducted regression analysis allowed us to obtain the equation of multiple nonlinear regression, which reflects the dependence of the raw gluten content in wheat kernels (Y, %) on the protein content (X1 = Ntotal · 5.7, %) and 1000-kernel weight (X2, g): Y = -41.928 + 0.081Х1 2 + 2.548Х2 - 0.028Х2 2. In the presented equation, all quality indicators are given at 12% humidity. If protein content and/or 1000-kernel weight are determined for absolutely dry matter (a.d.m.), the developed equation to predict raw gluten content in wheat kernels is recalculated with the use of coefficients of 0.88 and 1.136, respectively. The purpose of the research is to identify the effectiveness of raw gluten content prediction in wheat kernels using the developed regression equation, which reflects its dependence on protein content and 1000-kernel weight. There have been developed and presented an algorithm and results of testing the predictive capabilities of the equation based on independent data. That is, using experimental data on protein and gluten content, and 1000-kernel weight obtained by other researchers in the experiments with different wheat varieties and in other soil and climatic conditions. The summarized experimental data of 124 Soviet, Russian and foreign literary references with a total number of observations n = 2485 on more than a hundred wheat varieties grown from 1959 to 2019 in various soil and climatic zones of the USSR, Russia and abroad have shown that the number of values beyond the limits regulated by GOST R 54478 - 2011 (± 2%) was 462 or 18.6% of the total number of observations. The accuracy of the raw gluten content prediction in wheat kernels was 81.4%. The developed equation can be used to predict raw gluten content in kernels of various winter and spring soft and durum wheat varieties

THE PHYTO SANITARY SITUATION OF SPRING WHEAT SOWINGS IN THE NORTH-WEST OF NON BLACK EARTH (NECHERNOZEMIE) AREA

The conducted researches estimated a present phyto sanitary situation of spring wheat sowings in the north-west of Non Black earth area. A phyto sanitary situation is usually characterized with an average level of weediness, moderate infection with leaf diseases, and slight damage with pests. The varietal composition of harmful organisms and the species of economic value for spring wheat cultivation have been clarified for the region. They are 7 kinds of weeds, larvae of click beetles, Swedish oats fly and cereal aphids, powdery mildew, septoriosis, brown leaf rust. The article considers the change of the phyto sanitary situation under the influence of a variety, a forecrop, sowing terms and seeding rates, fertilizing. The varieties of foreign breeding are more susceptible to the local infectants that results in their strong infection with leaf diseases. The choice of a forecrop effects on a weediness of spring wheat and a damage of its sprouts with wireworms. The most favorable and popular forecrop for spring wheat is potatoes, the most unfavorable forecrop are perennial grasses. The late sowing terms of the crop worsen the situation with phyto pathogens. The grain infection with funguses increases that result in a black head, mold and root rot. The reduced sowing rates of spring wheat increase the weediness of spring wheat. Fertilizing promotes the formation of large phyto mass of weeds, increases the infection of plants with leaf diseases. The fields surrounded with forests are more resistant to pests, but less resistant to leaf diseases
