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

The results of the study of different types of growing of large-fruited watermelons in conditions of south zone of the Amur region are presented. Three promisingHollandearly ripening hybrids were tested. The optimal sowing time and ways of plant development were determined. The hybrids were fully characterized; the guidelines for their growing in the condition of this region are described.

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 development of new type of tea, the baikhovi black tea with leaves of amaranth (50:50), allowed the enrichment of tea by the compounds with vitamin P-activity, quercetine, rutin (3-times increasing), protein, pectin, key amino acids, vitamin C, calcium, ferrum, and organogenic silicon. Owing to the high content of red-violet antioxidant betacyanin in leaves of amaranth, the tea color was improved and antioxidant activity was increased.

The duration of interstage periods and fruiting time as well as their correlation with yield were studied. The correlation between density of early ripeness and density of interstage period «flowering-ripeness» was revealed.

Results of research of possibility of introduction of a new for the Russian Federation tuberous crop culture, sweet potato, are presented. The influence of planting dates on the yield of this culture was studied. According to the field experiment, the high yield of sweet potato tuber and resistance to diseases and pests were revealed.

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.

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.

Soil-climatic conditions of the South region of Dagestan are suitable for growing of winter cabbage. The yield of winter cab-bage in Dagestan farms is still very low because of low quality of seeds and non'observance of rules of cabbage seed production.

As a results of investigation, the new tomato varieties Eva, Narine, and an were selected for manufacturing application in different regions of Armenia. Cultivar Narine was registered in 2013. Cultivars Eva and Van are being tested for State Variety Trial.
