The results of research work on carrot seed growing through wintering seedlings carried out at laboratory of seed studies and seed production of Transnistrian Research Institute of Agriculture, on the soil of the first terrace at the rive Dniester were presented in the article. Seed bearing plants of garden carrot ‘Krasavka’ were the object of the study. The seeds were sown to produce the seedlings on 15-16 August. In the first decade of December the plants were covered with white agrotextile with density 23g/m2 that was removed at the beginning of April. The proportion of plant that passed the winter depending on a year of cultivation was 95-100% under argotextile, and 50-80% in open plot. The plants under agrotextile reached 28 cm a high and had 5-7 well-developed leaves, while those on the open plot were at phase of active foliage growing about 10-13 cm. long. Thus, for early mechanized planting in optimal terms the wintering seedlings grown under agrotextile had the best biometrical characteristics. Moreover the outcome of carrot seedlings was 1.2-1.25 million per hectare. Such quantity of seedlings was sufficient to plant 9-10 ha of carrot plants, where the coefficient of multiplication reached 9-10, and only 3 when growing seeds through mother plant as biennial culture. Viability of seed plants grown through seedlings was 100%. Losses of plant with weight 120-150 grams from damage caused by diseases was 23%. The seed yield, when growing seedlings was 639 kg/ha, but growing through plants was 332 kg/ha. The seed outcome suitable for precise mechanized sowing through seedling growing was 77%, where seed germination was 90%, with seed fraction 1.51 and >2.0 mm. It was essentially improved their yielding characteristics. Seed outcome from this fraction obtained through planting method was 32%. The proportion of seeds in fraction 1-1.5 mm was 68%. For mechanized single-seed sowing, the seeds can be used only after mini-coating. The seed growing from wintering seedlings fully excluded the application of fungicides for plant protection and seedlings from diseases; there are no expenses for building the expensive storage facilities needed for mother plant storing.

The experiments were performed during the two successive seasons of 2015-2016 and 2016-2017 at the Kazakh Research Institute of Potato and Vegetable Growing, Almaty Region, Kazakhstan. The experiment was aimed to study the efficiency of 117 different beetroot accessions for productivity and storability. To study the storability, 20 beetroot roots without any external sings of diseases were taken in two replications from each variety accession and left to be stored. The wet fresh weight of beetroots placed into storage varied from 132 g to 320 g depending on the shape and the size of roots. Beetroots were stored in polypropylene bags, which were placed on barred shelves 30-35 cm high. The storing temperature in autumn and spring period of time fluctuated from 3-5o to 6-8°, but in winter period it was 1-2°. The observed results showed that the gross yield of beetroot accessions ranged from 25.0 to 105.4 t/ha, marketable yield – 16.7 to 74.9 t/ha, marketability – 33.8 to 97.2%. Storability of beet roots mostly depended on accession genotype with different natural decrease of weight and root rot diseases. Natural decrease of weight varied from 0.0 to 12.3%, total losses from root diseases were from 0.0 to 90.0%. The analysis carried out showed that the link between yield capacity and storage characteristics was weak, R= -0,042-0,144. The correlation between storability and root rot was R = -0,516-0,644, that was stronger than it was in natural decrease of weight, R = -0.115.

Nutritional properties, benefits, economic importance of parsnip varieties ‘Krugliy’ ‘Lutshiy iz Vsekh’, ‘Serdechko’ ‘Beliy Aist, ‘Zhemtchug’ bred at VNIISSOK are discribed in the article. The descriptions of the varieties, methods of their development and technology for variety supporting are also given.

The standard methods of analysis don’t meet all modern requirements to determine the seed a quality. These methods can’t unveil inner deficiencies that are very important to control seed viability. The capabilities of new instrumental method to analyze the seed quality of root vegetables were regarded in the article. The method of micro-focus radiography is distinguished from other existing methods by more sensitivity, rapidity and easiness to be performed. Based on practical importance the visualization of inner seed structure, it allows determining far before seed germination the degree of endosperm development and embryo; the presence of inner damages and infections, occupation and damage caused by pests. The use of micro-focus radiography enables to detect the degree of seed quality difference for some traits such as monogermity and self-fertilization that are economically valuable for breeding program in red beet. With the aid of the method the level of seed development, damage and inner deficiencies in carrot and parsnip can be revealed. In X-ray projection seeds of inbred lines of radish significantly differed from variety population ones for their underdevelopment in the inner structure. The advantage of the method is that seeds rest undamaged after quality analyzing and both can be used for further examination with the use of other methods or be sown; that is quite important for breeders, when handling with small quantity or collectable plant breeding material. The results radiography analyses can be saved and archived that enables to watch for seed qualities in dynamic; this data can be also used at possible arbitration cases.

The study of the natural potential of density regulators of pests – such as entomophages and predators is interesting from both an environmental and an economic aspect. Fauna of most species and the degree of their effectiveness in the regional level have been little studied to date. Development of integrated plant protection involves the gradual replacement of highly toxic pesticides by biological means of plant protection, which is based on parasitoids and predators. The results of the study on faunal parasitoids of phytophagous in southern Dagestan are presented in the article, where their efficacies and survival under pesticide treatments have been also shown. As a result of research, the most resistant to the toxic chemicals was phase of Dibrachys cavus Walk. For the first time the information on the ratio among species (phytophage to entomophage) was given in the conditions of Dagestan, where regulatory function of the species in agrobiocenosis and their morphological descriptions were given as well. Species composition of the insect fauna and the dynamic of number of most spread ones were determined on the basis of systematic records in stationary areas according to the methods developed by G.E. Osmolovsky (1964), Paly V.F. (1966, 1970) and Fasulati S.R., (1971) et al. Identification of the species was performed according to identification guide by O.L. Kryzhanovsky (1974). The results are interesting to optimize the methods that can be used to protect the grapes from the most dangerous herbivores.

Winter garlic as a source of vitally necessary macro and microelements is very important in human's diet. Therefore, correlation links among accumulation the basic chemical elements in bulbs of winter garlic were estimated. It was shown that positive reliable relationship (r=0.71-0.85) was discovered between average potassium accumulation and elements, such as magnesium, aluminum and boron, and also between magnesium and boron accumulation, and between aluminum and magnesium. The correlation analysis showed negative relationship between cadmium accumulation with copper (r=-0.71) and silicon (r=- 0.66) accumulations. There is no significant relationship between lead accumulation and other element accumulation. The significant positive correlation was revealed between accumulation of radionuclides 90Sr, 137Cs in garlic bulbs and accumulations of aluminum, calcium, boron and magnesium with coefficients 0.74 and 0.85; 0.70 and 0.78; 0.65 and 0.77; 0.57 and 0.72, respectively. It was shown that accessions more resistant to diseases accumulated less cadmium (r=-0.47), but more lead (r=0.49). Moreover, it was noticed that accessions with high accumulation of potassium had the low percent of well-wintered bulbs (r=-0.57), but more accumulation of Zn and Fe caused the improved hardiness (r=0.80, 0.75, respectively).

The most part of tomatoes cultivated in Astrakhan oblast are transported in industrial centers of Russian Federation. Introduction of new cultivars suitable for mechanized harvesting and transportation has a considerable significance for tomato production in Nizhniye Povolzhye, and consequently, increases the profitability of vegetable production. At All-Russian Research Institute of Vegetable, Melon and Ground Growing several new-bred tomato cultivars passed the trial test, and thus, were shown to meet all requirements for upto-date agricultural technology.Two tomato cultivars 'Bokserskiy' and 'Klasicheskiy' were bred on the base of experimental data. These cultivars exceeded the standard 'Moriyana' in yield capacity, fruit weight, and had nearly equal biochemical composition. According to results obtained, it was shown that the fruits of cultivars 'Bokserskiy' and 'Klassicheskiy' were suitable for mechanized harvesting and long distance transportation.

Diverse technological methods are widely used in horticulture to improve the energy of seed germination, as well as growth and development of plants and their productivity. Ecologically safe methods to accelerate the plant growth processes are known as a presowing treatment of seeds and foliar feeding by plant growth-stimulating agents of natural origin. Pre-sowing seed treatment is necessary when plants grow and maturate not simultaneously, as noticed in amaranth. The action of growth-stimulating agents is an influence in slight concentration not only on biometrical plant parameters, but also on photosynthetic reactions and whole plant physiology. The seed treatment by preparations containing biologically active substances is not only ecologically safe methods but also an economically profitable. Consequently, improvement of quality in vegetable crops by high content of biologically active substances in them, such as polyphenols can be reached with technologies based on the use of preparations, containing biologically active substances and biogenic chemical elements. It was shown that distinctive feature of red leaf plants of amaranth cultivar ‘Valentina’ was a very variable concentration of phenolic compounds such as flavonoids (quercetin, apigenin and their glycosides), hydroxycinnamic acids, simple phenols, polymeric and condensed polyphenols in different aged leaves at the time of vegetation. Moreover, the metabolite variation, antioxidant in fractions of phenolic compounds, obtained from different aged leaves, was increased by biopreparations of natural origin. It is supposed that those preparations had an effect on stress-action system as in protective plant reaction, increasing the antioxidants content. The data obtained has shown that the plants of amaranth, as a promising source of antioxidants, can be used to develop functional food products and phytopreparations.

The long period of time needed for production of homozygous ms-and mf-lines in biennial crop is a problem in development of heterotic hybrids in red beet. The use of steckling culture and protected cultivation technology are the  suitable methods  to  speed  up  the  development  of breeding lines. However, the relationship between exhibition of CMS trait in seed plants and horticulturally valuable traits of steckling is very important aim of the study to be considered. The study was performed in 2012-2014. The red  beet  inbreeding  lines (I2-I5), obtained  through steckling culture in low-volume technology under protected cultivation condition were used as a plant material for the study. The generations that were obtained were from cultivar population ‘Nezhnost’ and a hybrid population of foreign origin. As a result, it was shown that one of criterions of indirect selection of ms-form in inbreeding generation may be the fast-maturity of stecklings that determined their yield weight at harvesting. The average weight of steckling belonging to sterile plants in progenies of different inbreeding generations, not depending on the time of harvesting was higher than in fertile plants. Therefore, probability to select the valuable ms-forms among groups of fast-maturing  plants with  greater weight  of steckling was higher. The selection of stecklings from smaller size groups of middle maturing and late maturing inbreeding progenies is required to  develop valuable mf-lines with high ability for fertility maintaining.
