Yu. V. Chesnokov
Construction of genetic maps has a principal value upon practical using revealed associations “marker-character”. Wide using molecular DNA-markers as well as application methodology identification and localization on chromosomes of QTL (quantitative trait loci) even in the case when it were no appearance new direction in science significantly allowed broadening of biological investigations, including precision and scalability in construction of genetic linkage maps. At the present investigation of gene linkage is one of most useful approach using for genome mapping as well as for genetic and breeding. Saturation of genetic maps gives possibility of compilation on map many segregated loci in one population up to full genome saturation. At the same time, effects of interaction “genotypeenvironment” can be as basis for variability, which is one of main reason why different populations some of the species not revealed identical length of the maps and differences can reach up to 20%. Gene, loci or even full-length chromosomes mapped in organism of one taxon with high percent of significance can be evaluate and identify with the aim conservative molecular markers mapped in other organism as a rule from the related taxon. Moreover, if it are carried out interspecies comparisons of prediction on arrangement and mapping of genes or QTL, which was made for one species can be apply to other relative to him species.

F. F. Rasulov
The sweet pepper varieties ‘Dar Tashkenta’ and ‘Tong’ were included in the State Register of Breeding Achievements in 1980 and 2005 respectively, and recommended for cultivation in the territory of the Republic of Uzbekistan. The planting schemes 70x30 (control), 70x20, 70x40, 70x40/2, 70x50 and 70x50/2 for these varieties were studied. The control variety was ‘Dar Tashkenta’. The feeding area and the number of plants per hectare embodiment was 0.21mІ2 and 47.6 thousand plants; 0.14 mІ2 and 71.4; 0.28 mІ2 and 35.7; 0.28 mІ2 and 71.4; 0.35 and 28.5 mІ2 and 0.35 mІ2 and 57.1 thousand plants. Studies were carried out in summer after harvesting early vegetable crops. During the spring period of the sweet pepper seedlings were planted in the second decade of April, they were planted in the second half of the month of June. It was shown that the planting samples and the density of plant standing had a different effect on the phenological phase of the varieties studied. In the variety of thickened ‘Dar Tashkenta’ (70x20 cm) to rarefied (70x50 cm) planting duration of about a period of from germination to 10% weight of technical maturity of the fruit was increased up to 8-10 days and amounted to 92-99 per day. The ‘Tong’ variety grew for 90-95 days. The phase of 75% of the technical ripeness of fruits in variety ‘Dar Tashkenta’ was for 108-114 days, in Tong for 104-110 days. The planting scheme has an influence on the following measurement parameters: the weight of the roots, the weight of the bush per plant, the number of leaves per plant, the area of the leaf blade, the number of stems of the first and second order, the length and diameter of the fruit, the number of fruits per one fruit set, the mass of fruit and yield. The number of plants from the first planting scheme to the last one was different and ranged from 28.5 to 71.4 thousand per ha. Therefore, the productivity of all varieties is estimated by the number of plants per unit area. Comparing with control (70x30 cm) variant, a low yield was obtained in both varieties with the planting schemes of 70x40 and 70x50 cm, according to the data 20.4 and 18.7 t/ha was in the ‘Tong’ variety 14.2 and 13.6 t/ha. In order to obtain a high yield, the optimal scheme of plant planting was recommended for ‘Dar Tashkenta’ and ‘Tong’: 70x20 and 70x40/2 cm, which corresponds to 71.4 thousand plants per hectare.

Vegetables are considered essential for well-balanced diets since they supply vitamins, minerals, dietary fiber, and chemicals. Thechilli pepper fruits (Capsicum spp.), like many other vegetable crops, are a source of important biological components – the macro-, microelements and antioxidants. In this regard, the chilli pepper can be included in the category of dietetic foods.The most cultivated in Russia chilli pepper varieties belong to the Capsicum annuum L. At present, in the world and in Russia huge number of varieties are selected, with different color, shape and hot and pungent taste of the fruits with a high content of carotenoids, capsaicinoids and ascorbic acid. These varieties belong to the species C. chinense, C. frutescens, C. baccatum and C. pubescens. The fruits of these forms and products of their processing are suitable for industrial applications and are the basis of many sauces, pastes, ketchups, and ingredients, which is used in food, pharmaceutical, confectionery, alcoholic beverage, military and other industries. Chilli peppers, in addition to nutritional value, are ideal for ornamental horticulture, because of the compactness or vice versa weeping form of the stems, suspended like bells and differently colored like a rainbow, fruits, colorful combinations color of leaves and fruits. You can use them and direct planting in the ground, and as a potting culture in balconies, loggias, winter gardens, in combination with other plants.

V. I. Burenin | A. M. Artemyeva
Contribution of cultivar in a harvest formation is approximately 70%. State registered list of Russian Federation includes about 9 thousand cultivars and hybrids of vegetable crops and cucurbits belonging to 117 species, 55-60% from cultivars was created by Russian breeders. The features of Russian assortment: large genetic biodiversity of cultivars and hybrids in duration of period of vegetation, resistance to biotic and abiotic stressors; existence of cultivars with very large areal; high part of individual sector in a structure of space and gross (from 50-60 till 75- 85%). The crops that are insufficient objects of Russian breeding have been shown and they need to use import cultivars. In the article the most important breeding directions have been noted: on earliness, resistance to insects and diseases, adaptiveness, high nutritive quality, breeding of energetic effective cultivars, on heterosis, importance of quick reaction on market demands have been shown. For creation of import substituted cultivars they need to use of VIR worldwide collection of vegetable crops and cucurbits that consists of more than 52 thousand accessions. It includes about 30% landraces, 45-50% – modern cultivars and hybrids, 3-5% –primitive forms and wild species, and also hybrid populations, inbred and mutant lines, double haploid lines, accessions with identified genes and chromosome loci, controlling valuable traits. The problems of seed production in Russia and ways of their decision have been reflected: state economic support and state control, use of ecological factors in seed production.

The process of embryogenesis and technological experimental protocol has been studied and applied to produce doubled haploid plants from microspore cultured in vitro in broccoli B. oleracea L. convar. botrytis (L.) Alef. var. italica Plenck. It was shown that successful embryoid development occurred from microspore isolated from buds 4-5 mm long, containing microspores at late vacuolated stage and pollen grain at twocell stage. The optimal temperature of treatment was 32 Cᵒ within 2 days after culture was launched. The embryoids were produced from the following broccoli accessions: Arcadia F1, Everest, Green Valiant, Marathon F1, and Furio. The highest embryoid yield was obtained from accession Green Valiant, and consisted of 140 embryoids per Petri dish, whereas the lowest yield was in Furio, up to 3 embryoids per Petri dish. The first microspore division was observed in all accessions in 2-3 days of cultivation. Further development of embryoids went either directly into usual embryoid or into suspensor-like structures. The embryoids with suspensor developed more slowly than embryoids without one. We observed the embryoid formation not only at distal end towards microspore originated the suspensor-like structure but also the formation of chain of embryoids, and all variation of twin embryoid combinations. The study of process of embryogenesis in isolated microspores in vitro showed that this method can be used both to produce doubled haploid plants and study the developmental stages of zygotic embryos and suspensors.

The success and timing of new varieties largely depend on the correct selection of the source material, representing the initial stage of breeding. This is especially true for plant species that have a two-year development cycle. The purpose of our research was to obtain intraspecific hybrids of chicory root. Research was carried out in the traditional area of growing root chicory – Rostov region of the Yaroslavl region. For testing the breeding process and obtaining promising lines us in 2014, there were direct steam crossing. A total of 14 samples of hybrid seeds were obtained, which were 2015-2016 sown for testing in the nursery source material. The article presents the data on the study of intraspecific hybrids of chicory root, they are evaluated in the nursery of the source material on yield, marketability, root shape, resistance to root rot during the growing season. Production requires varieties with short root, in which the bulk is concentrated in the upper part, combining high yields and resistance to root rot during the growing season. Among the hybrids dominated the cylindrical shape of the root. The conical shape had rooms Г1432 and Г1442 with root length of 20.0 cm, curved short form (16 cm) of root was different sample Г1462. This sample stood out spread sheet outlet with a strong anthocyanin coloration. As the yield of roots separated rooms Г1432, Г1452 and Г1441 (3.6; 3.4 and 3.7 kg/m2, representing a cash consideration of 133.3; and 127.0- 138.6% of the standard).

S. V. Glazkov | S. V. Koptsev | A. V. Samoylov
The article reflects the possibility of using the transformation of raw materials of vegetable type when using lactic acid organisms by the process of fermentation. The authors point out that such terms as salted, soaked and sauerkraut fruits and vegetables are widely used in vegetable processing technology and technical literature. In the canning industry there is a widespread salting cucumbers, tomatoes, pickled cabbage and beets, pickled watermelon and apples. The contamination of fresh cucumbers with lactic acid microorganisms is on average only 3-6%, and fresh cabbage from 5 to 20% of the total number of microorganisms. A significant place in the epiphytic microflora is occupied by putrefactive microorganisms and microorganisms of the genus Coli aerogenes. Contamination of vegetables microflora increases significantly during storage. As a result of the research, it was concluded that the total number of microorganisms on cucumbers that were stored for more than a day increased by 20-60 times and on cabbage with expired cabbage by 3-4 times. The article shows that the use of fermentation is one of the most popular and well-known ways to preserve fruits and vegetables from spoilage. This method relates to microbiological methods of preservation, which is based on the transformation of sugars contained in vegetables and fruits, lactic acid under the action of lactic acid bacteria, initially located on the surface of the processed raw materials. The task of the research was to study the process of directed fermentation of cabbage of white-leaved variety Slava, using strains of lactic acid microorganisms and their consortia, taking into account the degree of their mutual influence.
