Relevance. The genus Allium L. attracts the attention of researchers due to the presence of valuable medicinal, nutritional and decorative properties, adaptive capabilities, resistance to pests and diseases, ecological plasticity in its representatives, which contributes to the competitiveness of species and the manifestation of a high degree of adaptation outside natural areas and wide geographical distribution. Allium resources in Russia are a potential source of genes for expanding the genetic base of agricultural crops.The aim of the work was to establish the yield and change in the quality of green leaves of Allium species introduced into the Moscow region during short-term storage, depending on the type of packaging, storage period and temperature. 4-5-year-old plants of 4 species (A. altyncolicum, A. chyatophorum, A. nutans and A. turkestanicum) were grown on the collection plot of perennial onions of All-Russian Research Institute of Vegetable Growing – branch of the FSBSI FVSC.Results. In the conditions of the Moscow region, the yield per leaf generation varied from 2.7 kg/m2 (A. altyncolicum) to 4.9 kg/m2 (A. cyathophorum). The maximum yield of marketable products was noted in hermetically sealed plastic bags when stored for 10 days at a temperature of +6...8oС in a refrigerator with controlled conditions: A. turkestanicum – 70.0%, A. cyathophorum – 75.5%, A. altyncolicum – 84.9%, A. nutans – 92.9%. However, an increase in the dry matter content (10.1-15.5%) was found during storage in an open polymer box in all tested species. The maximum content of vitamin C during storage in hermetically sealed bags with a density of 100 μm was found in A. altyncolicum (37.1 mg%) and A. nutans (42 mg%). In other species, the maximum value of this indicator was noted before storage. A slight increase in the amount of sugars after storage for 10 days was noted in species with a linear leaf shape when stored in a polymer box.

Potatoes in all categories of farms in the Permskii Krai occupy 41.3 thousand hectares, in agricultural enterprises – 4.5 thousand hectares, with an average yield for 2014-2016 of 13.9 t / ha. The Permskii Krai there are all the prerequisites for obtaining high yields of potatoes. One of them is potato seed production. Variety, one of the important tasks of seed production, without it, with the ever-increasing need for new universal varieties that combine preservation of the original qualities for as long as possible, i.e. high stable productivity, early yield accumulation, good culinary and technical qualities (starchiness, good keeping quality, etc.) with resistance to the most harmful diseases, pests and adverse environmental conditions cannot be dispensed with. The purpose of research: the identification of promising varieties of potatoes, highly productive, in the Perm region. Investigations were carried out in 2011-2016 at the central experimental field of the Perm Agricultural Research Institute Branch of Perm Federal Research Center of Russian Academy of Science. In the collection nursery, 33 varieties of three groups of precocity were tested. A comparative assessment of potato varieties by yield and economic characteristics is presented. Promising potato varieties for cultivation under the conditions of the Perm Territory were identified in the group of early maturing: Albatross, Nandina, Latona, medium-early varieties: Irbit, 428- 05, Bravo, Miner, Amur. The varieties Crisper, Lukoshko, Bafana were the best in selected indicators in the mid-season group. Comparative assessment of potato varieties according to yield and economic characteristics is presented; studies were carried out at the Perm Agricultural Research Institute Branch of Perm Federal Research Center of Russian Academy of Science in the soil and climatic conditions of 2011-2016. Promising potato varieties for cultivation under the conditions of the Permskii Krai were identified in the group of early maturing: Albatross, Nandina, Latona, medium-early varieties: Irbit, 428-05, Bravo, Miner, Amur. The varieties Crisper, Lukoshko, Bafana were the best in selected indicators in the mid-season group.

Relevance. Shallots (Allium ascalonicum L.) is a very useful and promising crop with high nutrition- al, taste and medicinal properties. Shallot is appreciated for its tender and juicy tasty greens, as well as early ripening of bulbs with a long shelf life. For widespread distribution and consumption, increasing demand and popularizing this culture, it is relevant to create new promising varieties with valuable economically useful characteristics that meet modern market requirements. When creating new varieties, it is important to search for sources of early maturity, keeping quality, productivity, yield and quality.The aim of the research was to study local varieties of shallots for a complex of valuable traits, select the best forms and create a new fruitful, white early-ripening white variety of the salad direction, possessing useful properties, good keeping quality of bulbs, resistant to unfavorable environmental factors for cultivation in the regions of the European part of Russia.Materials and methods. The initial material consisted of 18 varieties of the local population from the North Caucasian group, differing in morphometric, in particular the color of the bulb (yellow to white), biological and economic characteristics. The studies were carried out at the collection site of the Krymsk EBS, VIR Branch (Krasnodar Region, Krymsk). As a standard, we used two varieties included in the State Register with the color of the bulb from yellow (Off-season) to white (Snezhok).Results. The study of phenological, biological, morphometric and economic characteristics made it possible to select five promising forms that are valuable for the consumer: those with early maturity, productivity, light color, large long-term bulb, green feather productivity, winter hardiness and good taste. The best form – LSh 5-05, with a consistently high yield, long-term keeping quality of white bulbs, marketability, good mild taste and attractive appearance, is included in the State Register of the Russian Federation for admission to use as a shallot Blondin variety.

Relevance. The production of onions and its preservation for the year-round provision of the population is an important strategic task. In March-May, there is often a shortage of onions due to high storage losses and incorrect determination of the optimal timing of implementation.Methods. Studies on the effect of fertilizers and plant growth regulators on the preservation of onion hybrids were conducted in 2014-2017 at the ARRIVG-branch of the FSVC. We tested 3 hybrids of onions grown in an annual culture on 6 variants of plant nutrition backgrounds. Harvesting of onions (turnips) was carried out manually, followed by drying in a greenhouse and laying for storage in a vegetable storehouse at a temperature of -1...0°C and a humidity of 80-90%.Results and discussion. The optimal duration of storage of new hybrids and the terms of sale of products when stored in cooling conditions for onions. Data on the shelf life and implementation of onion hybrids, depending on the nutrition background, are presented. Mathematical descriptions of the dependences of the total losses of 3 modern hybrids on the duration of storage and the influence of fertilizers and growth regulators are obtained, which is of great practical importance for the agricultural and industrial complex. Conclusions. A positive effect on the preservation of onions of treatments of vegetative plants with solutions of potassium nitrate (10 kg/ha), Zircon (0.25 l/ha) and Tenso Cocktail (0.7 kg/ha) against the background of N90P90K90 was revealed. The maximum yield of marketable products after 7 months of storage at -1...0℃ and 80-90% humidity in Bennito F1 was on the N90P90K90 + KNO3+ Zircon + Tenso Cocktail variant-89,6%, losses from diseases 2,8%; Poisk 012 F1 on the variant with the use of Zircon against the background of N90P90K90-52,1%, losses from diseases 31,2%; Pervenec F1 on the N90P90K90 + KNO3 variant- 91,4%, losses from diseases 1,4%. Pervenec F1 was distinguished by the best preservation during three-and seven-month storage. In general, the use of micro-fertilizers and a growth regulator had a positive effect on the preservation of onions.
