The results of estimation of 2 varieties and 6 collection samples of winter garlic (Allium sativum L.) of resistance to accumulation of plumbum, cadmium, cuprum, and mercuric in condition of the Moscow region are presented. The biochemical content of the studied samples of winter garlic is shown.

This article describes the features of the development of male sterility trait of functional type in patty"pan squash. The viability of pollen grains in different periods of vegetation was studied. The determined fertility ability of pollen can be used for hybrid seed production of different varieties of pumpkin.

The content of macro- (C, N, P, S) and micro-elements, as well as some metals was analyzed in fruits, leaves, stems, and roots of vigna, kiwano, bitter melon, and wax gourd growing in the condition of unheated  polyethylene-covered greenhouse  in Novosibirsk (Russia). The revealed low concentration of sulfur and big atomic ratio of nitrogen to sulfur in plant phytomass is the result of insufficient macro-elements supply from fertilizers and peatsubstrates. The kiwano fruits are characterized by high concentration of K , Ca, Mg , Zn, Fe, Cu, and Ni and therefore is worth introducing this culture in Russia.

The two varieties of parsnip, «Krugliy» and «Beliy aist», were estimated for micro-and macronutrients. The differences in accumulation of 25 micro-and macro-elements between two varieties were revealed. It was found that parsnip is the source of phosphorus, potassium, magnesium, ferrum, calcium, silicon, cobalt, chrome. The cultivar «Krugliy» is able to accumulate the high concentration of iodine.

The paper presents the results of research on the presence in genomes of pea hybrid materials of the DNA regions complementary to the primers that are associated with the biochemical characteristics and resistance to powdery mildew.

The storage of yield of potato depends on quality of potato tuber. During storage the respiration process and evaporation are the cause of natural loss of potato tuber biomass. In our experiments, the loss of mass depended on variety, tuber size, and place of growing. During first day of storage, the natural loss of biomass of cv. «Rosara» was 2,9-3.1%, and cv. «Udacha» – 1,9-6,3%.

In condition of Ramenskyi district (Moscow region) there was wide spreading of minstrel bug (Graphosoma lineatum L.), which is cause of yield loss of vegetable crops of Umbelliferae family. It was found up to nine mature insects per one plant. The larvae and imago feed mainly on buds, flowers, and seeds in all stages of its development. Because of damaging the seed productivity is decreased by 11-45%, the weight of 1000 seeds is decreased by 12-40%, germination energy is decreased by 13-100%, and germination ability is decreased by 10-82%. The germless seeds can range from 5% to 15 % and seeds without endosperm can range from 7% to 36 %.

The species of pests spreading in cabbage planting are listed in the article. The recommendation for the herbicides application for cabbage protection against different pests is presented. The ways of improvement of herbicides application are shown.

The previously unknown and not wide spread pathogen of carrot, Trychothecium roseum L., was revealed. The etiology and pathogenicity of this pathogen were studied.

The results of tomato lines resistance test to tomato spotted wilt virus and its comparison to molecular marker SCAR Sw421 genotyping data is shown. A molecular marker SCAR Sw421 analysis allowed identifying homozygous and heterozygous tomato genotypes possessing Sw5 alleles in segregating populations. Selected tomato lines possessing dominant homozygous alleles of Sw5 gene represent a tomato germplasm resistant to tomato spotted wilt virus and would be useful for following crop improvement.

As a result of long-term study and several rounds of selection, the new variety of eugenol type of basil «Zhemchuzhina Podmoscovya» was developed for the Central Region of Russia. This variety was included in the State Register of selection achievements.

The specification for performance of technological operation for cultivation, storage, and transporting of original tomato varieties are presented. The standards for technological process was developed for the first time in Russia.

Based on data of varietal and sowing characteristics of caw pea seeds the organizing standard "Cow pea seeds. Varietal and sowing characteristics. Specifications" STO 45727225-40-2011 was developed.

The results of influence of topping on the development of the leaf surface and photosynthetic ability of plants of vegetable bean are presented.

The results of influence of types of irrigation and soil mulching on weed infestation, yield, and phytosanitary state of late-ripening white head cabbage are presented. Using of drop-irrigation increased the yield of the crop. The mulching of soil decreased the weed infestation and degree of development of black rot of white head cabbage at all types of irrigation.

The optimal combination of soil treatment and herbicides application in condition of the light chestnut soils of the Volgograd region is suggested.
