The problem to choose and use ecologically plasticiable cultivar accessions is one of the most important stage of the program for adaptive vegetable production. The right decision of the problem leads to rational utilization of material and natural resources, decreasing the expenses and charges. For successful development of vegetable breeding the cultivar adaptive specifications is necessary to know. Vertical zonation along with hydrothermal condition had an essential effect on yield of red beet. Not being depended on maturity type of cultivar accession their yield increased by 1.9-3.2 t/ha successively from plains towards mountain zone, corresponding to pre-mountain and mountainous regions in Chechen Republic. On average, for tree-year study the highest yield was 45.8 and 45.1 t/ha in cultivars ‘Bona’ and ‘Tsilindra’ respectively, not being depended on the zone of cultivation. The cultivars ‘Donskaya Ploskaya’ (flat), and ‘Odnorostkovaya’ were sources of ecological resistance, while the cultivars ‘Boltardy’ and ‘Detroit’ were sources of productivity. The cultivars ‘Boltardy’ and ‘Gribovskaya Ploskaya’ that had been responsive on regulated environmental factors and resistant to unregulated environmental factors were of multipurpose usage and intensive-cultivation type. The ‘Bordo 237’, Dvusemiyannaya TCKHA’, ‘Odnorostkovaya’ and ‘Tsilindra’ were distinguished from other by accumulation of dry matter and total sugars in all zones of cultivation. On cultivation zone change from steppe towards pre-mountain and mountainous region, the tendency was revealed that dry matter, total sugars and vitamin C content had increased, while the nitrate content had only depended on cultivar features.

The basic research results of Russian breeding program in Brassica crops were given in the article. Conventional breeding as well as biotechnological methods were used to develop hybrids that meet all requirements of current vegetable market. Brief communication information on international scientific and practical conference “Current State and Trends in Breeding and Seed Production of Brassica crops” was given in the article.

The main problem of agroindustrial sector of national economy is an absence of sufficient production of plant proteins that are used for food production as well as a forage production. New cultivars of  legumes, namely in  soybean have to  be developed to resolve this task. Soybean seeds contain much protein up to 50%, fat up to 28 %, along with  vitamins, phospholipids,  isoflavones and ferments. Soybean is a short-day crop. The main reason that limits the spread of soybean is the absence of new early-ripening cultivars. Folk cultivars and varieties native to China produce the grain yield at the sum of temperatures over 3500oC. At the beginning of the last century, there were bred the varieties that  produced  the grains at the sum of temperatures  below  3000oC.  Only after  that  the soybean as a crop is started to be introduced in different countries. The study on association among quantitative traits is needed to select necessary accessions for breeding program. In this research estimation of correlationship based on data of structure analysis was carried out within two-year period.  The correlationship  of  economically valuable traits, such as 1000 seed grain weight, number of grains in bean (pod) and other traits such as plant height, stem thickness, the height of pod  attachment, a number of branches, number of pods on the plant, number of productive nodes, average number of pods at node, average number of grains (beans) per plant in field experiment in 2015-2016, Central Zone of Non-chernozem Zone of Russia. It was noticed  the difference in trait correlationship depended on a year, and it needs to be taken into account for realization of breeding program in soybean.

Economical  efficiency  of  agricultural  industry  is  a major characteristic of the level of development of an enterprise. A profit from product sale depends on volume and structure of product  sales, self-cost as well as the level of  sales price.  Thus, the gross revenue from cultivated crops and vegetable cultivars can be observed at the time of fruit harvesting. The total sum of  the gross earnings from  the harvest, determining the  efficiency  of  enterprise can  be  calculated  as a product of values of daily price and mass of total harvest. There are no challenging points in the condition of permanent price and vegetable harvest. Even the registration of average-sales prices for vegetable doesn’t make the production difficult. But real market situation essentially differs from accepted practice to register average-sales prices with relatively permanent vegetable  harvest.  The  price  indexes  of  sales  for tomato and cucumber produced in greenhouse in Udmurt Republic with showing the dynamic of retail price for vegetables were presented in the article. It was shown  that  prices  of  tomatoes  and cucumbers had the seasonal factor that meant weekly price wavering.  The  temporal  row  harvest  of  cucumber ‘Tseres           F1’  and  tomato  ‘Admiro  F1’  produced  at Zaviyalovskiy greenhouse enterprise was  described. The average derivation between nearest and last harvest was in the  gap  23%  to  29%  in cucumber  and reached up to 70% in tomato. The values of such derivations were occasionally provoked and determined by some inter-enterprise factors. The construction  of trend lines for such series and further line evaluation with  the aid of  determination  coefficient  R2  showed extremely low quality of model  of the kind y=a•x+b. The value of R2 cubic  polynominals was in the limits R2=0.32-0.46. Essentially, plans for vegetable production,  constructed  on  the  basis of  this  linear model should be regarded as unsatisfied. According  to the analysis presented above, it is worth concluding  that the principles to plan the production process in greenhouse enterprises have to be changed. As an example, the use of tk value as a shift of harvest time for kcrop related to price maximum for the crop used can be very effective.

In conditions of maintenance of environment parameters for plant growth, the use of nutrient solutions prepared with non-deficient fertilizers is an effective method of reducing the cost of vegetable production. The article examines economic prospects of the use of technologies of small-volume (0,15 — 0,3 l./per plant) the intensity of light-culture of plants in nutrient solutions, prepared on the basis of industrially produced fertilizers ‘Rastvorin A’, ‘Akvarin’, ‘Agricola’ and ‘Kemira Lux’, which are recommended for leafy crops. ‘Knop’ solution as one of the most effective for intensive technologies of the light-culture of leafy crops was used as a control. The object of study was a lettuce, cultivar ‘Tayphun’ and parsley cultivar ‘Bogatyr’. Plants were grown under different levels of light irradiance. Light during the growing period for both species was for 12 hours, the temperature was maintained at 20-22C° in the day and 18-20C° at night, air humidity between 60-65%. The duration of the vegetation period is 25 days. As a result of the study, it was shown that the productivity of lettuce cultivar ‘Typhun’ and parsley cultivar ‘Bogatyr’ that were grown on nutrient solutions ‘Agricola’ and ‘Rastvorin’ was very high. The content of nitrates for all cases was not extended more than the MCL. The highest productivity in the range of irradiance between 60 and 40 watts has been observed in lettuce plants of cultivar ‘Typhoon’, grown under light-culture system with the use of nutrient solutions ‘Akvarin’ and ‘Agricola’. Thus, the study carried out has showed that nutrient solutions ‘Akvarin’, ‘Agricola’ and ‘Rastvorin’ can be recommended for cultivation of leafy crops under condition of changeable light irradiation.

Napa cabbage is well spread in Japan, China, Korea, but it is not so well known in Far-Eastern regions of Russia. Since 2012 the collection of hybrid accessions has been evaluated at agrobiological station of Blagoveschensk State Pedagogical University located in western part of Blagoveschensk. Twenty local and foreign hybrids have been studied. As a result, seven highly-yielding accessions of different terms of maturity have been selected and included into State Register of Breeding Achievements of Russian Federation.  The  complex  assessment of  most  promising hybrids for uniform heads and excellent consumer’s characteristics has been performed  under the condition  of south zone of Amur oblast.

Humic compounds occupy the important place in the chain plant – water. Their application in technologies for vegetable plant growing with the use of drip irrigation enables to increase the coefficient of nutrient compound assimilation from soil with applied fertilizers. The preparation ‘Lighohumate’ presented in the article is integrated fertilizer, possessing the properties of anti-stress, immunomodulator and sticking agent. This preparation has the highest content of humic acids to 20% for liquid and to 90% for dried, consequently it has a powerful influence on plant organism, opening hidden biological  reserves, and improving  the crop  productivity.  The experimental tests showed that ‘Lighohumate’ application trough drip irrigation system together with foliage fertilizers had given significant yield augmentation; 5-20% depending on medium and technology in vegetable crops cultivated with different agricultural techniques. The permanent speeding-up from 3 to 12 days was noticed in the course of plant development with increase of early yield outcome. ‘Lighohumate’  can be used as seed treatment agent as well as foliage fertilizer and already applied giving a result in many vegetable production enterprises.

35 viruses have been reported to infect peppers (Capsicum spp.) and those lead to economic losses like low  and  variable yield. Viral diseases are an important factor  provoking  low  yield and reduced  fruit  quality. In low volume hydroponics the spread of virus infection had local character. The two types of symptoms were revealed. The plants with symptoms of green mottle, chlorosis, deformation of mid-rib  in top leaves, and leaf blade rolling by edges inwardly were observed in breeding accessions with light-green fruit color such as ‘Maria’, ‘L-Ochrovanie’,  ‘Belosnezhka’. The deformation,  mottle and symptoms of inner necrosis can be seen on fruits. The degree of disease development reached 100%. The results of  enzyme-linked immunosorbent  assay (ELISA) and ImmunoStrips assays enabled to identify the tobacco mosaic  virus  (TMV). There  were  blight-yellow   mottle, wrinkling on entire plants and deformation and mottling on fruits. The symptoms appeared on the top leaves by the end of vegetation period that was caused by late viral impact. The degree of developing the disease was 10.5-25% on leaves and fruits that was less than on plants with green mosaic. Immunological  tests carried out  in open field showed the combined virus infections, consisting of TMV+CMV  with  degree  of  disease  development  was 37.5%. The rod-shaped particles, 30 nm in size, belonging to tobacco mosaic virus were discovered with the use of electron microscopy in pepper plants showing the symptoms of green and yellow mosaic.

The early-ripening variety of garden pea ‘Kudesnik 2’ was proposed for State Commission for variety trial in 2015 and regarded to be used in the canning industry. The variety was bred at Krymsk Experimental Plant Breeding Station and considered to be used for continued conveyor-like production for further processing technology at canned-food production enterprises.

White head cabbage (Brassicа oleracea L.) is the most widespread crop. Climatic condition in Amur oblast is very favorable to cultivate cabbage crop that has been traditionally used. However, there are released cultivars ‘Podarok’, ‘Nadezhda’, ‘Belorusskaya 455’, ‘Moscovskaya pozdnaya 15’ that do not meet all requirements for economically valuable traits. Results of study of cabbage collection including local and foreign hybrids have been carried out in soil and climatic condition of open field in Amur oblast. Advantageous hybrids with set of economically valuable traits have been selected out to be used and recommended for cultivation in crop farming of Amur oblast.
