For five years, the effect of cultivars and vegetative stage of cutting were measured on red clover (Trifolium pratense L.) seed production. The first group of cultivars included Hungaropoli, Ottawa and Lakeland harvested in 1981 and 1982. The second group included Arlington, Florex and Prosper I harvested in 1984, 1985 and 1987. The total annual seed yield differed within cultivars and the highest seed yield was obtained with Hungaropoly and Florex. In the first cultivar group, the tetraploid Hungaropoly obtained a kernel weight higher than the diploids Lakeland and Ottawa. In the second group of cultivars, all diploids, Arlington yielded the highest kernel weight. The percentage of seed germination of Hungaropoly was higher than Lakeland and Ottawa while for Florex it was slightly higher than Arlington and Prosper I. A prior vegetative cutting is essential for good seed yield. In the absence of vegetative cutting seed weight seemed improved. The stage of development at which vegetative cutting is done has little influence on percentage seed germination. These results have shown that despite the strong effect of climatic conditions on seed production, the choice of the optimum stage for vegetative cutting and a well adapted cultivar are important aspects in successful seed production.Key words: Red clover, seed production, cultivar, stage of cutting

The Creation

The article reflects the issues of the current state of scientific research at the FSBSI FSVC, shows the directions and prospects for the development of selection and seed production of vegetable crops. The main mission of the selection and seed-growing work of the FSVC is the creation and reproduction of varieties and hybrids of vegetable and melon crops of a new generation, characterized by resistance to abiotic and biotic stressors, high productivity and product quality. One of the main ways to increase the efficiency of the breeding process is the use of modern methods of biotechnology and molecular genetics, which make it possible to obtain new genotypes and reduce the time of breeding. Success has been achieved in the creation of homozygous lines of cabbage, squash, cucumber, carrots. For the first time, it was possible to complete a full cycle of obtaining doubled radish haploids in microspore culture in vitro. The institution pays special attention to immunological research on the resistance of crops and new varieties to diseases, as well as protecting plants from pests and diseases. Phytosanitary monitoring, assessment and selection of resistant genotypes are carried every years. One of the important theoretical and practical problems solved at the institution is the development of environmentally friendly products based on preparations obtained from plants with a high content of biologically active compounds with adaptogenic properties. In the center, a new direction of research in traditional breeding has received significant development - the creation of varieties of vegetable plants with an increased content of biologically active substances and antioxidants, on the basis of which functional products are created. The persistence of modern varieties and hybrids of table carrots, depending on the biochemical composition, has been studied. Methods for enriching vegetable plants with micronutrients are being developed. A large amount of scientific research is being carried out on the development of technologies for the cultivation of new varieties and hybrids, as well as technologies for their seed production. At the branches located in different soil and climatic conditions, hospitals were established to study the interaction of factors controlling soil fertility and the productivity of vegetable crops in agrocenoses (crop rotation, soil treatment systems, fertilizers and plant protection). In general, at the FSBSI FSVC, all research is aimed at developing and improving methods in breeding and seed production of vegetable crops, creating new breeding achievements and developing varietal technologies for their cultivation.

<p>In the article, a comprehensive evaluation of the role of organic farming in the formation of the crop and the nutritional value of perspective varieties cultivated within the climatic zone of Western Siberia is considered. The most favorable conditions for growing potatoes in the Altai Region of the Western Siberia are compared with other regions of Russia and those of foreign countries.<br />In the southern and southeastern regions of the Altai region, where the formation of tubers coincides with the hot period of the first half of summer, the high soil temperature negatively affects the eyes of the tubers. Therefore, the seed material here rapidly degenerates. To avoid this, summer potatoes are planted. Irrigation ensures high and stable potato yields irrespective of weather conditions. Moisture content of soil during the period from planting potatoes to shoots should be maintained at the level of 65-70 per cent, in the budding and flowering phases - of 75-85 per cent and during the period from the beginning of wilting of potato tops – of 60-65 per cent. The number of irrigations, their terms and standards, are determined by taking into account soil-climatic conditions, the phase of plant development and the application area of a crop.<br />The most effective irrigation method is sprinkling. The irrigation norm ranges from 500 to 800 m3 per hectare. On irrigated lands, plowing of potato fields is carried out necessarily with a soil cultivator, preventing the formation of a plow pan. Rows are located across the slope, or angle-wise. After watering space between rows are loosened (on heavy soils also before watering). During irrigation process it is necessary to apply higher quantities of organic and mineral fertilizers and to carry out a set of measures to control weeds, pests and diseases of potatoes.<br /><br /></p>

Current climate changes in Russia are attended by the increase in frequency of dangerous weather events. This chapter researches long-term variations of the dangerous weather's events on Western Siberia and to reveal general regularity, which can be associated with forest fires. The researches have been carried out for the territories of southeast of Western Siberia. The duration of the fire season increases due to climate change. This is due both to the earlier snowfall and the onset of the phenological spring, and to the increase in the duration of the thunderstorm period. Thunderstorms in Siberia are a much more frequent cause of forest fires (28%) than in other territories. Wildfire frequency is correlated with air temperature and drought anomalies.

Hydrothermal Regime

Seed production of perennial leguminous herbs, including meadow clover (Trifolium praténse), is complicated due to the natural and climatic conditions of the region. In Middle Urals, only two to three years out of ten are favorable for seed production. Estimation of influence of the hydrothermal regime of the growing season and the sowing method has been carried out in the experimental crop rotation of the Udmurt Research Institute of Agriculture, UdmFRC Ural Branch of the RAS with the seed grass stand of meadow diploid clover varieties Pelican and Trio, tetraploid variety Kudesnik It has been revealed that seed productivity of meadow clover on sod-podzolic medium loamy soil was more dependent on the prevailing hydrothermal regimes of vegetation periods, as well as on the variety’s ploidy. A relatively high seeds yield of the Pelican variety (2n) 444-593 kg/ha and Kudesnik variety (4n) 101-116 kg/ha was formed under conditions of insufficient and optimal moisture supply of the vegetation period with a hydrothermal coefficient of 0.67-1.41. With increase in hydrothermal coefficient p to 1.56-1.69, the seeds yield of the Trio variety (2n) decreased to 251-328 kg/ha, of the Kudesnik variety (4n) - to 77-91 kg/ha. Under the same conditions, according to the hydrothermal regime of vegetation, the Kudesnik clover variety formed a relatively larger number of stems and heads, however, the heads productivity was significantly inferior to diploid varieties, which ultimately affected its seed productivity. Sowing diploid varieties of meadow clover Pelican and Trio in the usual ordinary way (15 cm), tetraploid variety Kudesnik in a wide-row way (30 cm) allowed increasing seeds yield and thereby neutralizing the negative impact of weather factors. Sstudy of the seed formation features of meadow clover varieties differing in ploidy in contrasting agrometeorological conditions may be of interest in developing methods for optimizing their seed productivity.

To achieve good health standards of potato seed, the site of potato seed production should be aphid free at least for 90 days or the number of aphids/100 compound leaf should not be more than 20, which is the critical level of aphid numbers. In the year 2010-11, 2011-12 and 2012-13, 40 varieties of potato of CPRI, Shimla were planted in main crop seasons at Central Potato Research Institute Campus Modipuram (Meerut) and observations were recorded on the population buildup of M. persicae starting from arrival to attain its maximum. The population of aphids was different on potato varieties during different years and on the basis of observations, it was difficult to predict which variety to be first preferred by aphids. Kufri Girdhari recorded the least number of aphids.

For the rapid distribution and successful cultivation of beans, it is necessary to develop methods of cultivation technology in accordance with the soil and climatic conditions of Krasnodar region. In this regard, the aim of this work was to study the efficiency of irrigation, various doses of mineral nutrition and the use of the biological product Nitragin KM on grain beans crops. The effect of pre-sowing application of mineral fertilizers under irrigation and rainfed conditions on phenological, morphological traits, yield and productivity of grain beans variety Yuzhanka has been studied. Analysis of the data on the yield of beans seeds showed that the most effective agricultural method for seed production of this crop is the introduction of mineral fertilizers on drip irrigation. With an increase in the level of mineral nutrition, the seed multiplication factor increased from 30 to 45 pcs/pcs on dry land and from 50 to 69 pcs/pcs during irrigation. The application of mineral fertilizers contributed to an increase in yields both in rainfed and irrigated conditions. The highest yield of bean seeds of variety Yuzhanka was obtained with the use of fertilizers at a dose of N30P30K30 (1,77 t/ha on dry land and 3,04 t/ha on irrigated plots).
