Depending on the genotype of monoecious plants Cucurbitaceae family may have different gender expressions: predominantly female, mixed and predominantlymale type of flowering. However, the degree of sexual differentiation can be changedunder the influence of abiotic and endogenous factors. Among the chemicals that affect the level of female flowering in pumpkin crops, preparations based on 2-chloroethylphosphonic acid (Ethephon or Etrelle) are the most promising for hybrid seed production. Study of plant response of squash Cucurbita pepo var. giromontina with varying sex expressions on the treatments with Etrelle revealed common conformities and specificities of preparation action in the condition of Krasnodar region. It is shown the use of treatment once is not effective even if the high concentration range, 500-1100 mg/L, was taken. On gender switch was effectively influenced successive plant treatments with Etrelle at stages of 3-5 true leaves in a wide concentration range from 250 to 700 mg /L., where the restraining was that the start of male flower blossoming was 14-25 days after female flower blossoming. K69 line with predominantly female flowering was more responsive to the variation of concentration and frequency of treatments whereas the line K49 with male flowering was less responsive to the frequency of treatments. It is shown that in the range of effective concentrations, Etrelle may have phytotoxic effects on the growth and development of squash plants at the time of restraining flowering of male flowers. It is important to  ake that into account when choosing a regime of preparation treatments for chemical castration of maternal forms in hybrid seed production of this crop.

Selection of infected material for research was carried out in experimental carrot plots at GNU VNIIO (Moscow region), Voronezh OOS (Voronezh oblast), Baraccudas OOS (Rostovregion) and Israel. The first year plants of carrot, the roots, were used for the study. There are many scientific papers cited where many different methods of artificial infection of plants with fungal disease pathogens were given to control the stability of carrot genotypes in various phases of plant development. One of the ways to lead the purposed breeding program for resistance is the extraction of pathogens isolates and the method of fast assessment on the basis of determining the aggressiveness of new strains and their use in breeding work. This article presents a method of inoculation of cut-discs of root. A great advantage of the method is in its efficiency and the current results can be obtained within 2 weeks from the moment of infection. As a result, the work on the isolation of fungi from carrot plants, the pure culture collection of strains: Alternaria radicina and Fusarium avenaceum was obtained. The characteristics and morphology description of colonies of isolates of RR. Alternaria and Fusarium found in carrot plants taken from different ecological and geographical zones were given. The most aggressive isolates of the following ecological and geographical zones as Alternaria at Moscow and Rostov regions, Fusarium at Voronezh and Moscow regions were revealed. These isolates will be used as standards of aggressiveness for the test of newly isolated strains regarded as inoculum to conduct immunological experimentsin carrot breeding for resistance to Fusarium and Alternaria.

A model of late maturing F1 hybrid of white head cabbage for long-term storing and suitable for national recipe “golubci” have been developed based on requirements for varieties and F1 hybrids grown in the South in the conditions of drought, high temperatures and low air humidity. Combining ability of seven self-incompatible inbred lines of white head cabbage was studied by the system of full diallel crosses in conditions of Pridnestrovian Moldavian Republic. These lines were developed on the base of heat tolerant varieties ‘Biruchekutskaya’, ‘Volna’, ‘Lada’, ‘Moldavanka’ and ‘Kharkovskaya Zimnyaya’ bred in the south. Out of 42 hybrid combinations studied 15 significantly surpassed in productivity the variety ‘Zavadovskaya’ that is traditionally grown by local farmers for pickling and recipe “golubci”. High GCA effects for productivity showed the following breeding lines: Bu1, Ml3 and Kl5. Polygenes, controlling the high yield ability, mainly were dominant and single-directed, however the correlation betweenyield ability and GCA effect was middle, r=0.63±0.35. No correlation was observed inbreeding line between GCA effect and truly heterosis effect in hybrid combinations (r=0.19). Disease resistance analysis revealed lines Bu1 and Kl5 that had shown resistance to Fusarium yellows. Two hybrid combination Kl5xBu1 and Ml3xBu1 were highly tolerant to thrips attacks according to analysis of all promising hybrid combinations, carried out in natural infection background. Weak correlation was observed between the number of damaged leaves in cabbage head and dry matter content, r=0.41±0.21, and also there is no correlation revealed with sugar contents, ascorbic acid and nitrate content. High tolerance of hybrids with participation of line Bu1 explained the partial dominance nature of the trait. Hybrid combinations Kl5xBu1 and Ml3xBu1 called ‘Batal’ and ‘Shedevr’, respectively, included in registry of Moldova and PMR.

Wide use of cucumber hybrids F1 into industry is only possible at the use of lines with female type of flowering as maternal forms. There are difficulties to select such sort of lines and moreover these lines phenotypically may look entirely like female ones often showing the population nature that may be revealed by treatments with growth  substances. Many researchers came to conclusion that gender variationexpressed much in plant ontogenesis and depended on growing conditions. Consequently, to speed up development of female forms, the different growing conditions may be used as provocative background condition. At VNIISSOK in 2013-2015, some self-pollinated female lines with complex of economically valuable traits including resistance to diseases were selected. All these lines under spring greenhouse condition were shown to be entirely female type, belonging to gynoeciumgender type which is characterized by presence only female flowers on the plant. At the same time gender type of the best maternal lines was assessed for economically valuable traits in open field condition. As a result, it was shown that not all female lines, which were entirely female ones in greenhouse condition, also had not male flowers in open field condition. It may be supposed that increase of volume of breeding material being studied and plant growing under harder condition of open field - day and night temperatures variation, lack or abundance of humidity and others - enable to carry out more precise assessment of gender type of maternal forms. According to results of analysis, the open field condition served as provocative background to reveal cucumber lines with strong expression of female flowering. It enabled to have selected eight most promising accessions, which were taken into crossing to test their combining ability.

The objective of the research was to study the process of directed fermentation of whitehead cabbage variety ‘Slava’, using strains of lactic acid bacteria and their consortium with the degree of their mutual influence. As strains of lactic acid bacteria, we have chosen the following: VCR 536 Lactobacillus casei, Lactobacillus plantarum VKM V-578. To obtain comparable results, all experiments were performed on model mediums. For the first time we studied the dynamics of changes in quality indicators at the process of directed fermentation using strains of lactic acid bacteria (LAB) including their consortiums. The mathematical model developed adequately describes the degree of destruction of glucose and fructose in the fermentation process. The raw material was undergone to homogenization and sterilization with the aim to create optimal conditionsfor the development of the target microorganisms and to detect the degree of  restruction of fructose and glucose by different strains of microorganisms. The mathematical model developed adequately described the degree of destruction of fructose and glucose in the treatment process. The use of a consortium of lactic acid bacteria (L. plantarum+L. casei) to this culture medium is shown to be impractical. The addition of fructose in quantity 0.5% to weight of the model medium enabled to intensify significantly the process of white cabbage fermentation.
