The results of the industrial cultivation of pea seeds in farms of Belgorod region are shown.

Developed by the academician Dragavtsev the method of ecologically geographic analysis of the polygenic characters proposes the study of different ecologically genetic systems such as adaptation, attraction, photoperiodic sensitivity, factors of limitation of mineral nutrition, etc.

The analysis of the modern homeland assortment of vegetable crops is given. The donors of the most important traits and the accessions  of vegetable and melon crops perspective for breeding from the VIR collection are shown. The short characteristic of the varieties is given.

In this article, the main stages of establishment and development of the laboratory of breeding and seed production of cucurbits crops since 1921 are presented. More than 50 varieties of cucurbits crops were developed. Research envelopes and main achievements of the laboratory in field of production of high yielding varieties of cucumber, pumpkin, and squash resistant to biotic and abiotic stresses are discussed.

The development of technology of vegetable growing in the condition of protected area is presented. Data of planting acreages and assortment of crops growing in greenhouses in different countries are shown. Development of the popular in recent years hydroponic culture is presented. The problem of information acquisition about acres, structures and yield capacity of protected ground of different countries is underlined.

Results of field experiments of the study of seasonal abundance of Colorado potato beetle in different potato varieties. It was shown that some varieties developed through conventional breeding are able keeping its resistance when threshold of harmfulness is exceed.

The peculiarities of accumulation of radionuclides 137Cs and 90Sr in different organs and tissues of vegetable crops have been studied. Aim of this research was the enhancement of safety and quality of food at the cost of the elimination from the food ration of the vegetable organs with high ability to accumulate the radionuclides

The biochemical content of stachys nodules is provided: dry matter -30,5%, among which proteins - 2,2%, amides - 1,7%, lipids- 0,2%, carbohydrates- 19 % (reducing sugars - 1,8%, cellulose - 2,1%, pectin - 1,9%. Stachys has big amount biologically active substances and antioxidants such as vitamin C, stachyose, phenolic compounds, flavonoids, and glycosides. Stachys also has micro- and macro-elements and mineral compounds, which play important role in physiological and metabolitic processes of plant and human.

Using the sporophyte selection accelerates in three times the breeding process of new tomato forms with dgenes for the multilevel narrow-shelve hydroponic technology. Analysis two breeding approaches is presented in this paper: the individual selection of recombinant forms from populations and the target hybridization. The target hybridization increases the productivity of the plant and the weight of one fruit in two times.

The collaborative work on growing of leafy turnip in condition of salad production line was conducted in ООО PKF «AGROTIP». The possibility of obtaining of ecologically safety salad turnip of cv. Selekta, Sapfir, and Biryuza at hydroponic system are shown. Data of yield, productivity, and content of ascorbic acid in green leaf of turnip growing in condition of flow hydroponic system are presented. The possibilities of using of tested turnip varieties in modern agrotechnological systems are discussed.
