One of the modern selection tasks in vegetable growing is quality products improving, obtaining high yields of environmentally safe wide assortment vegetables. To the new varieties of vegetable crops including winter white cabbage are specified new requirements such as market competitiveness, resistance to unfavorable environmental conditions, heat resistance of the varieties and F1 hybrids. The article is shown investigation results about studies of exogenous treatment by solutions on the base of physiologically active compounds of hormonal nature on the started process of stem extension stage activation and flowering of winter white cabbage plants. For the first time in the Dagestan conditions has been studied the possibility of hormonal regulation of the premature stem extension stage and flowering prevention of winter white cabbage after the initiation of natural induction. In our studies with an early planting there are not more than 20% of blooming plants, most varieties showed a high propensity to premature stem extension stage and flowering. The possibility of the hormonal exogenous regulation of the unfavorable winter white cabbage flowering has been revealed. The most pronounced effect on the transition to stem extension stage and flowering were provided by auxin nature preparations. In particular, treatment with NAS at a dose of 5 mg / l significantly reduced the number of blossom plants, krezatsin (50 mg / l) had a similar effect, but it was less pronounced. The use of cabbage in winter crops makes it possible to obtain two or three yields per year from the same area. Creation and introduction into production of promising and high-yielding varieties and hybrids will allow increasing production and reducing its cost.

ABSTRACT The aim of this study was to obtain new broccoli lines with cytoplasmic male sterility trait for the development of the modern F1 hybrids. CDT70 cauliflower line obtained in the Research Institute of Horticulture, formerly Research Institute of Vegetable Crops, Skierniewice, Poland, with the reliable cytoplasmic male sterility from Raphanus sativus (Ogu-INRA) was selected as a source of this trait. Three broccoli lines: BMi, BCr1 and BCr2 were used as donors of commercial characters in all cross combinations with sterile components. Selected fertile broccoli genotypes were characterized by good quality, uniformity and high level of self-compatibility. The breeding procedure included three consecutive back crosses of male sterile genotypes with fertile broccoli lines that lasted from 2008 to 2012. In each generation, self-compatibility level, the stability of the male sterility trait and ability for the generative propagation of back-crossed genotypes were tested in comparison with donor broccoli lines in the greenhouse. The agronomical and morphological characters of the back-crossed progeny were also evaluated in the field. As a result, three CMS broccoli lines of Bc3 generation with good quality and high seeding index, suitable for the breeding purposes, were obtained.

The aim of present investigation was the assessment of the several new onion hybrids develop through three- way cross along with their parents for having less problem of weight losses due to sprouting and rotting, and long storage quality at normal room temperature and relative humidity. The design of experimental plot was complete randomized block design (CRBD) with three replications. This study was carried out in the year of 2018-2019 at Division of Vegetable Crops, ICAR-Indian Institute of Horticultural Research, Hessaraghatta, Bengaluru, India. Thirty hybrids developed by three- way cross, thirteen parental lines and one check have been included for the experiment. Three F1 hybrids used as female lines and ten commercial varieties used as male testers, were taken to develop the hybrids through line x tester design. The bulbs of all these genotypes were kept for four months in normal storage chamber at 25-30°C room temperature with 65-70% relative humidity. The overall losses of per cent bulb weigh was recorded and conclude that the three-way hybrids TWCHO-15 (26.91) were recorded for smallest amount of loss followed by TWCHO-5 (27.02), TWCHO-14 (28.83) and TWCHO-4 (29.98). These hybrids can be suggested for more profit to onion grower by keeping for long shelf-life.

In the conditions of covered crop in Dagestan tomato ranks the first in terms of cultivation area and in the country it is the second place after cucumber. However, tomato production has not yet reached the level necessary to meet people’s need. Growing it allows solving the problem of import substitution, ensures a constant supply of fresh vegetable products and solves the problem of a balanced, complete nutrition human nutrition throughout the year. When studying vegetable crops in covered crop conditions were revealed both general provisions characteristic of any region and specific features depending on the complex of local natural conditions. The level of radiation, temperature, humidity, wind and snow loads leave a certain influence on the growing tomatoes technology, which makes the problem of developing scientifically grounded elements of technologies for their production, ensuring high yields of vegetable plants and environmentally safe out-of-season products. With a wide variety of soil and climatic conditions in Dagestan, territories with extreme natural contrasts, even within a single agroclimatic region, the features of light and other microclimate regimes require clarification of the most important elements of agricultural technology. One of the main components of tomato growing technology is timely protection against diseases and pests. In the absence of a system of protective measures yield losses can reach 50% or more. In this context, the assessment of new F1 hybrids in film greenhouses in the winter-autumn circulation was carried out, the most promising of them for the conditions of Dagestan were identified, and the main elements of their cultivation were developed. The article presents the results of the dynamics of the yield of the crop by months. The influence of sowing and planting dates on the tomatoes yield is shown, the optimal scheme of sowing and planting tomatoes is determined. A phenological calendar for plant protection was compiled. The prospects of growing the studied hybrids in this region have been substantiated. Обоснована перспективность выращивания изучаемых гибридов в данном регионе.

The use of heterosis is a forward direction in white head cabbage breeding program. This strategy enables to serve characteristic and yield improvements compared with best cultivars currently being used. At present time, the most suitable way to produce the hybrid seeds of cabbage is crossing between self incompatibility lines. 4-line crossed hybrids Avrora, (ultra fast ripening), and Snezhinka (mid-late ripening) with use of self incompatibility were obtained. The andro-sterile form has been multiplied by biotechnology methods and the sterility maintainers have been tested and fatherly forms have also been multiplied.

Southern root-knot nematodes (Meloidogyne incognita) are an important re-emerging pest of watermelon in the United States and worldwide. The re-emergence of root-knot nematodes (RKNs) in watermelon and other cucurbits is largely the result of the intensive cultivation of vegetable crops on limited agricultural lands coupled with the loss of methyl bromide for pre-plant soil fumigation, which has been the primary method for control of RKNs and many soilborne diseases of cucurbits and other vegetable crops for several decades. One alternative for managing RKN in watermelon is the use of resistant rootstocks for grafted watermelon. We have developed several RKN-resistant Citrullus lanatus var. citroides lines (designated RKVL for Root-Knot Vegetable Laboratory), which have shown promise as rootstocks for grafted watermelon. In 2011 and 2012, we demonstrated that F1 hybrids derived from our selected RKVL lines exhibited resistance to RKN that was equal to or greater than that of the parental RKVL lines when grown in fields highly infested with M. incognita. In 2011, although significant differences were not observed among rootstocks, the F1 hybrids produced slightly higher yields compared with the selected parental lines. Among the selected parental lines, RKVL 318 produced high yields in both years. In 2011, three of four RKVL parental lines and all four of their F1 hybrids produced greater (P < 0.05) fruit yields than self-grafted ‘Tri-X 313’, ‘Emphasis’ bottle gourd, and ‘Strong Tosa’ squash hybrid. In 2012, three RKVL F1 hybrid lines produced higher yields than the selected parents. Overall, these F1 hybrids were vigorous and should provide useful genetic material for selection and development of robust RKN-resistant C. lanatus var. citroides rootstock lines.

The possibility of increasing hybridity in alfalfa (Medicago sativa L.) cultivars through the use of self-incompatible (SI) parents is being investigated. Prior research has demonstrated that self-incompatibility is a heritable trait and that environmentally stable SI clones can be selected. However, inbreeding depression is very severe in alfalfa, and a potential problem associated with utilizing self-incompatibility to increase hybridity is the purported positive relationship between self-incompatibility and inbreeding. Fifteen stable, partially to fully self-incompatible clones and 18 stable self-compatible (SC) clones were selected from the broad-based population W10-AC3. RAPD, Anchored Microsatellite Priming (AMSP), and Simple Sequence Repeat (SSR) analyses were performed on genomic DNA using 9, 10-mer RAPD primers; the AMSP primers (from the 5' end) CAA(CA)5, CCCC(GA)5, CCG(GA)5, and GCC(GA)5; and eight SSR primer pairs. Based on genetic distance (GD) estimates (computed from RAPD and AMSP markers) and numbers of tri-allelic and tetra-allelic loci from SSR analysis, there is no evidence that SI clones were more closely related than SC clones. Assuming parental GD is positively correlated with heterosis, environmentally stable SI clones with acceptable specific combining ability and separated by large GD's would be a good basis for a hybrid alfalfa system, or for use in other breeding schemes designed to minimize inbreeding while maximizing heterosis.
