Relevance and methods. For the Non-chernozem zone, the main factor for the active development of late blight is the low air temperature and its sharp fluctuations during the day, contributing to the formation of increased air humidity and drip-liquid moisture on the plants. In the Moscow region, the causative agent of late blight is manifested almost annually. Populations of Phytophthora infestans are represented by the To and T1 races. Epiphytotic development was observed periodically (1977-1979, 1982, 1986, 1996-1999, 2000, 2001, 2003-2004, 2008-2009, 2013, 2014, 2015, 2016, 2017, 2019) and was provided by the virulent T1 race. Observations showed that epiphytotic situations arose in those years when the minimum air temperature was below long-term average values, and relative humidity and precipitation exceeded them. With a deviation from the norm in the direction of increasing temperature, decreasing rainfall and relatively low humidity, years were observed with a depressive (1992, 1994) or moderate development of the disease (1980, 1981, 1983, 1985, 1987-1991, 2002, 2005-2007, 2010-2012, 2018). Results. As a result of breeding work, a Grot tomato-tolerant tomato variety was obtained, on the basis of which varieties with high resistance Grand, Dubok, Gnom, Chelnok, Patris, Geya, Zolushka, Perst, Severyanka, Blagodatny were obtained. In the general collection of VIR as a source resistance to leaf spot pathogens were registered: Geya (v.k. 14839), Slavyanka (v.k. 14840), Patrice (v.k. 14841), Rossiyanka (v.k. 14842), Krepysh (v.k. 14843), Sibiryachka (v.k. 14444) and line 1079-94 (v.k. 14845) donors, in addition to their high resistance to late blight, have excellent economic characteristics.

Relevance. In the conditions of the dry-steppe zone of lowland Dagestan, the beneficial effect of drip irrigation in combination with dump cultivation on the yield and quality of sweet pepper fruits from Moldova proved. Results. It experimentally established that maintaining moisture in the active 0.5 m soil layer during the growing season within 80- 100% of LMC against the background of dump processing to a depth of 0.23-0.25 m led to an increase in yield and biochemical composition of sweet pepper fruits. Differences in the influence of dump and small (0.10-0.12 m) tillage on agrophysical and phytosanitary indicators of fertility of meadow medium loamy soil were revealed. The data showing the inappropriateness of using small-scale cultivation under conditions of irrigated vegetable growing, which leads to a deterioration in the agrophysical indicators of fertility: increase in soil density by 0.05-0.08 t/m3, decrease in the number of water-resistant units by 7,0%, water permeability reduction by 22.0% and water resistance coefficient by 12.9%, 2.1 times increase in planting weed and 212.6% potential soil weed. Of the three studied thresholds of soil moisture (70, 80 and 90% LMC), it was established that the best conditions for plant growth and development, optimization of their photosynthetic activity are created at a humidity threshold of 80% LMC, at which the most efficient use of irrigation water is noted. Drip irrigation with maintaining the pre-irrigation threshold for soil moisture not lower than 80% of against the background of dump processing leads to an increase in the number of fruits on 1 plant, an increase in the mass of 1 fruit, which contributed to an increase in yield to 62 t/ha.

Relevance. One of the most important directions in the breeding and variety study of fruits, in particular domestic plum European, is the breeding of cultivars with high commercial and consumer qualities of fruits. In this regard, the assessment of some commercial and consumer qualities of fruits in plum cultivars of the RRIFCB gene pool was of great practical and scientific interest. Material and methods. As objects of research, we used 8 plum cultivars of the RRIFCB gene pool and a control cultivar of the RRIFCB breeding Bolkhovchanka.

Results. Most of the studied plum cultivars from the gene pool of the Russian Research Institute for Fruit Crops Breeding have valuable commercial and consumer qualities of fruits, which will allow them to be used in further breeding for this trait. Cultivars Californiyskaya krupnaya, Zarechnaya rannyaya, Volgogradskaya can be recommended for further use in breeding as sources of high fruit mass. Cultivars Californiyskaya krupnaya and Bolkhovchanka can be recommended for further use in breeding as sources of high pulp content in fruits and fruit sizes. On the basis of the tasting assessment of the fresh fruits, the fruits of the cultivar Volgogradskaya stood out positively.

Relevance. The non-chernozem zone of Russia and the more northern regions of the country are far from the most favorable zones for the cultivation of tomatoes in open ground. The most promising for the northern zones of Russia are earlyripening, cold-resistant varieties and hybrids of tomato. The most promising in terms of productivity, resistance to short-term frosts and late blight damage are standard and semi-standard forms of tomato. Stamp forms (var. validum Brezh.) are of significant interest, both for breeding, genetic studies of tomato culture, and for production.Results. In the laboratory of selection and seed production of solanaceous crops of the FSBSI FSVC (VNIISSOK) in recent years, a whole series of standard early ripe tomato varieties for open ground has been created (Chelnok, Revansh, Pervotsvet, Argo, Evgeniya, Malinka, Otradny). The involvement of the selected standard forms in the crosses made it possible to create a number of promising lines and varieties of the semi-standard form (Perst, Pervotsvet, Blagodatny, Dolgonosik, Voskhod VNIISSOK), which significantly increases the genetic diversity of the standard forms. These varieties with a solids content of up to 7.5%, with a long shelf life. In the non-chernozem zone and the more northern regions of the country, the VNIISSOK selection varieties easily tolerate a short-term decrease in day and night temperatures to 0…-1°C, and in the southern regions drought.

Relevance. Vegetable seed production is a key step in using of new varieties/hybrids in agriculture. The main problem of vegetable seed production is the negative effect of environment to the seed productivity of plants and seeds quality. Usually, vegetable seeds produce in greenhouses in Russia, but special greenhouses are necessary for the obtaining of qualitative seeds. Possibilities different types of greenhouses for seed production of new special tomato varieties for multi circle hydroponics have been studied at this paper.Materials and methods. Materials of study: plants, fruits and seeds of two new tomato varieties Natasha and Timosha. Influence type of plants cultivation on the yield, plant productivity, the middle mass of the fruit and seeds quality have been studied at the two factorial experiment, which has been carried out with help of random repetitions method with 4 repeats. Seed quality has been evaluated by GOST 32 592-2013. Experimental data have been calculated with dispersion analysis by B.A. Dospekhov (1985).Results. It has been established, that the environment of “Rishel” greenhouse (France firm “Rishel”) with polycarbonate cover is optimal for the seed production of new tomato varieties Natasha and Timosha for multi circle hydroponics. The productivity and the yield of seed’s plants were significantly higher in “Rishel” greenhouse, than in the usual greenhouse. The middle mass of one fruit at the plant was significantly higher too. The quality of seeds was in accordance to GOST 32 592-2013 for qualitative tomato seeds (2014).

Relevance. In modern climatic conditions, the suppression of production process occurs against the background of short-term or long-term exposure to unfavorable environmental factors on agricultural plants, and, therefore, yield decreases. In this regard, there is a need for the use of growth regulators with protective and stimulating effects on many physiological processes.The aim of the work was to study the influence of the element selenium and 6-benzylaminopurine on the production process of red currant.Methods. Foliar treatments with solutions of sodium selenite and 6-benzylaminopurine (6-BAP) were made after flowering plants of the Dana and Asya varieties of the VNIISPK. The currant leaves were taken from annual shoots for determine the content of abscisic acid (ABA), the amount of pigments, and the rate of light reactions of photosynthesis. The parameters of the fruit brush of plants were recorded.Results. It was shown that treatments with sodium selenite and 6-benzylaminopurine contribute to a decrease of 2.1-3.5 times in the leave tissues of the endogenous ABA level, increase the chlorophyll biosynthesis by 27.5-48.0% and accelerate by 19.3-45.8% electron transfer rate on the level of light photosynthesis reactions. Treatment with selenium and 6-BAP of Dana plants increased the average mass of the fruit brush by 19.30% and 24.5%, respectively, Asya varieties by 20.7 and 35.8%. The increase in the average mass of the fruit brush occurred due to the enlargement of the average mass of one berry in it. It was shown that selenium and 6-BAP in the Dana variety increased the weight of the berry by 27.3% and 47.3%, in Asya by 33.3% and 45.8%. The treatment did not have a significant effect on the amount of sugars. Thus, for increase the production process, it is advisable to make foliar treatments with sodium selenite and 6-BAP during the growing season on red currant plants.

Relevance. A rare representative of the Apiaceae family the garden chervil is widely used abroad in nutrition and in folk and traditional medicine.Methods. Evaluation of nutritional potential of Anthriscus cerefolium (L.) Hoffm and Anthriscus sylvestris Hoffm grown in Moscow region is achieved using the parameters of ascorbic acid, polyphenols, flavonoids, total antioxidant activity of ethanolic extracts.Results. Garden chervil (Anthriscus cerefolium) was characterized by lower concentrations of ascorbic acid (1.6-1.8 times), phenolics (2.2-2.5 times), flavonoids (1.8-2.2 times), total antioxidant activity (1-1.54 times) and dry matter content (2.4-4.9 times) than wild chervil (Anthriscus sylvestris) but demonstrated significantly higher levels of total dissolved solids. Significantly higher content of dry matter in leaves and especially stems of wild chervil correlates with low nutritional value of stems despite large total mass of plants compared to garden chervil. Contrary to wild chervil, Anthriscus cerefolium recorded unusually high concentrations of carotene in leaves and significantly lower levels of chlorophyll b. Seeds of garden chervil were also characterized by low antioxidant status contrary to wild chervil and seeds of curly parsley. High yield and significant nutritional value of garden chervil indicate important prospects of its wide-scale cultivation in Russia while Anthriscus sylvestris plants seem to be important in breeding processes.

Relevance. Biofortification of agricultural crops with selenium is considered to be the most promising method for the human selenium status optimization.Methods. Effect of foliar biofortification of cauliflower, Polyarnaya Zvezda cv, with sodium selenate of different concentrations on yield, selenium content and biochemical characteristics of plants were investigated.Results. Enrichment of plants with selenium increased yield by 1.23-1.31 times, sugar content – 1.6 times, ascorbic acid concentration – 1.52-2 times. On the contrary, the treatment did not affect pholyphenol content and antioxidant activity of ethanolic extracts of plants. Selenium accumulation levels decreased according to inflorescences > leaves > roots. Sodium selenate solution at 75 mg/L concentration increased mass of cauliflower leaves 1.9 times and roots – 1.5 times. Consumption of 100 g of cauliflower fortified with 50 mg/L sodium selenate solution provided 100% of the daily adequate selenium consumption level. Utilization of higher sodium selenate concentrations ensured 127% and 418% of the daily adequate consumption level in case of 75 mg/L and 100 mg/L concentrations respectively. Taking into account insignificant differences between sugar content and antioxidants in cauliflower inflorescences fortified with different doses of selenium the most suitable concentration to be used was 50 mg/L.
