The fraction composition and content of phenolic compounds in vegetable plants with high content of polyphenols is presented. The developed functional foods is a complex of antioxidants such as dehydro- quercetine, quercetine, rutin, amaranthine, etc., which can be used for immune system reinforcement, against dysbacteriosis, and promotion of health.

In field experiments, the optimal pre-irrigation moisture levels of the soil, plant density and fertilizer regulations to ensure maximizing the table beet crops with good qualities of roots under foothill zone of the Chechen Republic have been found.

The summary report of research investigations of the institutes of the Russian Academy of Agricultural Science, the Russian Academy of Science, and the Institutions of Higher Education in 2013 on the project «Development of new varieties and high-precision sustainable zonal technologies of vegetable and cucurbits crops growing with the use of new varieties and hybrids, high'quality seeds, advanced approaches of agro-techniques, plant protection, and mechanical equipments» is represented.

The study shows the stability of dill varieties to fusarium in the Moscow region.

The optimal scheme and plant density of non-seedling tomato culture for seed production purposes in condition of Dagestan Studied were determined.

The problem of biodiversity conservation and use of raw plant materials for the needs of humankind is the most urgent nowadays. The introduction of new crops with improved resistance to adverse environmental conditions, diseases and pests reduces the pesticide load and improves the sustainable agriculture. Vegetable husk tomato has a great adaptive potential and it is suitable for growing in the south and in the north regions. This crop is resistant to the most com mon diseases and pests in the open field of the centralRussia. Due to the cold tolerance of husk tomato the under winter sowing in open ground is possible.

Selenium accumulation level in basil plants is investigated. A direct correlation between selenium concentration and essential oil content is demonstrated for basil and other aroma plants. No correlation is found between selenium and flavonoids.

Using of the DH–lines of two mapping populations of Brassica rapa L, the morpho–biological investigation and mapping of QTLs determined some morphological traits of quality in greenhouse's condition have been done. The linkage groups of QTLs of the following quantitative traits have been identified and localized: length, width, color, hairiness, and surface of lamina, as well as petiole length and width caused of nutritive value of B. rapa plants. The molecular markers genetically linked with mapped QTLs were revealed. The percent of phenotypic variability determined by the identified chromosome loci was calculated.

Control of seed production of vegetable crops based on factor of quality is become the basis of modern management. There is a growing need in the fastresponse devices for determination of moisture and temperature in seeds and environment.

Data of bioenergetic assessment of two strains of oyster mushroom in conditions of basement with different light intensity were obtained. The energy for the product development and the energy accumulated by the economically valuable part of yield were evaluated. The high ratio of the bioenergetic efficiency (up to 2,42) was revealed for the strain НК-35 when the day-light lamps at 600-800 lux of intensity were used.
