Abstract. This article presents the results of a long-term study of a set of oat varieties in the southern forest-steppe zone of the Omsk region. The estimation of parameters of ecological adaptability for protein collection per unit area is given. Purpose. Long-term study of a set of oats varieties in the conditions of the southern forest-steppe zone of the Omsk region according to environmental adaptability parameters calculated on the basis of “protein collection per hectare”. Methods. The research was conducted from 2013 to 2017 in the conditions of the southern forest-steppe of Omsk. A detailed analysis of the adaptability parameters is provided: the indicator “protein collection per hectare” according to Zykin, ecological plasticity index according to Eberhart and Rassel, stability factor according to Lewis, homeostaticity and selection the value of varieties according to Khangildin, relative stability and stability criterion according to Sobolev, intensity according to the method of Udachin. The final adaptability of varieties is estimated by the sum of the ranks obtained by each variety for the studied parameters. Results. The results of the research have shown that they are most adaptive in the southern forest-steppe zone Omsk region filmy varieties Orion, Uranus and Sibirskiy Gerkules (total ranks 34–44) and Sibirskiy golozernyy (total ranks 61). Scientific novelty lies in the study of 13 varieties of membranous and hulless groups of oats, recommended for cultivation in the Omsk region. The collection of protein per hectare is an integral parameter that takes into account two indicators: the actual yield of the variety and the content of crude protein in the grain. Therefore, studies on this indicator are not popular. For the first time, thanks to the adaptive characteristics, varieties are divided according to this characteristic into intensive and extensive. The grouping of varieties depending on the cultivation areas is also given.

Early Maturity

The article presents tests of natural creeping apple trees and natural dwarfs, carried out in the in the conditions of the Orenburg region. There were from 50 to 100 trees in the experiment in each variant. Vigorous standard plantations were used as control. The aim of the research was to test natural creeping apple trees, natural dwarfs against the background of standard varieties bred in the South Urals (Chelyabinsk), as well as to determine their prospects for intensive horticulture in the extreme conditions of the region. The preservation of plantings for all variants of the experiment for 20 years of research is high and amounted to 92-99 %, their condition was estimated at 4.5-5.0 points. The highest yield was noted for natural dwarfs (457.2 c/ha), the smallest yield was obtained on vigorous standard plantings (control) – 238.7 c/ha. Naturally creeping apple trees in terms of productivity were higher than control by an average of 25 %. Of the naturally creeping varieties, the most productive were the varieties Podsnezhnik (348.3 c/ha), Chudnoe (335.2 c/ha), the least productive were the varieties Plastun and Kovrovoe (255.1 and 262.5 c/ha, respectively). On the natural dwarfs, the most productive variety was the variety Brat Chudnogo (461.2 c/ha). In the control, the most productive varieties were the varieties Symbol (295.9 c/ha) and Nadezhda (270.5 c/ha), less productive were the varieties Pamyat Zhavoronkova and Fevralskoe (208.0 and 224.1 c/ha, respectively). Low-growing plantations, in particular layer and natural varieties of the Urals, are distinguished by their early maturity and, in general, higher productivity per unit area. The highest labor costs are accounted for by natural dwarfs (485.4 person-day/ha) and the lowest in vigorous plantings (317.4 person-day/ha). This has a positive eff ect on the profit and rentability of production.

Research 2019-2020 in the conditions of the forest-steppe zone of the Chelyabinsk region showed that the effect of glauconite on the yield and seed productivity of potatoes largely depends on the variety. The effect of glauconite (in doses from 10 to 40 t / ha) on the yield of tubers was proportional to the duration of the growing season of the varieties. The highest yield gains from glauconite were observed in the mid-ripening variety Tarasov – 4.05–4.62 t/ha, then in the medium-early variety Nevsky – 3.26–3.63 t/ha, and the smallest – were in the early variety Rosara – 1.95–2.26 t/ha. Whereas the effect of glauconite on the seed productivity of varieties had the opposite pattern: the greatest increase was observed in early-maturing varieties (Rozara – 1.30–1.56 times, Nevsky – 1.30–1.61 times), and the smallest – in the mid-season variety Tarasov (1.17–1.25 times).

The Impact

The impact of contrasting conditions of water availability on the size of the upper internodes in wheat varieties was studied under the conditions of the Orenburg steppe zone. It was noted, that less drought-resistant varieties formed a short upper internodes. We conducted a mathematical analysis of the relationship of productivity and length of ear-carrying internodes of spring soft wheat varieties of different ecological groups. It was established, that we can observe a gradual increase of grain productivity with increasing the length of the upper internodes in the studied range. As a result, the following varities were selected for inclusion into the hybridization: Logachevka, Tulaykovskaya steppe, Tulaykovskaya 1, Tulaykovskaya Belozernaya, Prokhorovka and Uchitel. They have the optimal settings for the presented feature. Using the selected varieties as parental forms can enhance the efficiency of wheat breeding programs for resistance to drought in the forest-steppe zone of the Southern Urals.

New Variant

The diversity of weed-field communities of sunflower crops within the forest-steppe zone of the Orenburg Region (Abdulinskiy, Matveevskiy, Oktyabrskiy, Aleksandrovskiy, Sharlykskiy districts) was studied. The communities in the system of ecological-floristic classification units are assigned to the new variant Orobanche cumana of the Amarantho blitoides - Lactucetum tataricae Khasanova et al. 2019. In the core of the cenoflora of communities juvenile weed species prevail. The most active of them are late spring annuals ( Amaranthus blitoides , Panicum miliaceum , Amaranthus retroflexus , Setaria viridis ) and early spring annuals ( Chenopodium album , Fallopia convolvulus , Camelina microcarpa ). Root perennials such as Lactuca tatarica , Convolvulus arvensis , Euphorbia virgata , Cirsium arvense have also a high proportion. A distinctive feature of the communities is the participation in their floristic composition of a dangerous quarantine species - Sunflower broomrape ( Orobanche cumana ). Modeling the area of the association under a moderate scenario of climate change shows that the distribution of communities by 2050 can cover almost the entire territory of the Cis-Urals (within the Republic of Bashkortostan). It is necessary to organize a monitoring system for the range of these communities in the Southern Urals.

Современная экономика диктует необходимость быстрой и эффективной окупаемости затрат, вложенных в производство продукции садоводства, что требует интенсификации отрасли. Одним из путей решения поставленных задач является закладка садов на клоновых подвоях, обеспечивающих высокое, стабильное плодоношение, с плодами отменных вкусовых качеств, подбор новых подвоев, приспособленных к условиям Крыма и не уступающих по комплексу хозяйственно-биологических свойств районированным в регионе. В статье освещены результаты многолетнего изучения 14 клоновых подвоев в сочетании с двумя сортами яблони. Определена сила роста изучаемых привойно-подвойных комбинаций в почвенно-климатических условиях Предгорного Крыма. Комбинации сортов Аскольда и Ренет Симиренко с подвоями ЕМ-IX, КД 4, КД 5 по показателям параметров кроны относятся к слаборослой группе. Деревья на К 104 по силе роста занимают положение промежуточное между ЕМ-IX и ММ-106, но имеют хорошо развитую корневую систему и компактную форму кроны. Выделенные комбинации рано вступают в плодоношение (на 2-3-й год). Средний урожай таких насаждений равен 24,4-30,6 т/га. Отобранные подвои обладают большим биологическим потенциалом и эффективными хозяйственно-биологическими свойствами, и представляют интерес для южного садоводства. Modern economy necessitates quick and effective return of costs invested in the horticultural production, which requires the intensification of the industry. One of the ways to solve the assigned tasks is to establish gardens on clonal rootstocks ensuring high and consistent fruiting with crops of excellent palatability traits, selection of new rootstocks adapted to the conditions of Crimea and not inferior in terms of the range of economic and biological properties to those released in the region. This paper highlights the results of long-term study of 14 clonal rootstocks in combinations with two apple varieties. The growth power of the studied scion-rootstock combinations in the soil and weather conditions of the Piedmont Crimea was determined. Combinations of ‘Ascolda’ and ‘Renet Simirenko’ varieties with rootstocks EM-IX, KD 4, and KD 5 in terms of crown parameter values belong to a dwarf group. Trees on K 104 are intermediate between EM-IX and MM-106 in terms of growth power, but have a well-developed root system and a compact crown shape. The above mentioned combinations enter into fruiting very early (on the 2nd-3d year). The average yield of such plantations is 24.4- 30.6 t/ha. The selected rootstocks are of great biological potential and effective economic and biological properties, so they are promising for southern horticulture.

On the basis of summarizing the results of many years experience on environmental study varieties and breeding numbers of spring wheat, we can base models of early maturing, middle maturing and mid-season varieties for the forest-steppe zone of Orenburg region. The identified dependence of grain yield on the productivity elements, morphological and structural features, the assimilation apparatus parameters, biological and physiological characteristics reliably described by the equations of regression. Such kind of varities, as Varyag, D-1847/97, Omskaa 20, Prokhorovka, Samsar, Saratovskaya 42 and Solveig were high adaptive capacities in this area. It is well to combine the best parameters of efficiency elements of main spike in favorable years: Kinelskaya 59, Lyuba, Moskovskaya 35, Orenburgskaya 13, Prokhorovka, Saratovskaya 55 and Enita; in dry years: Logachevka, Saratovskaya 42, Solveig and D-1847/97. The optimal parameters of the assimilation apparatus were observed in the following varities: Volgouralskaya, Varyag, Kinelskaya 59, Logachevka, Lyuba, Prokhorovka, Solveig, Tulaykovskaya 1, steppe Tulaykovskaya and Enita. The use of hybrid models in the selection of breeding material and varieties, selected as parent forms to better address selection on efficiency and sustainability in the forest of the Southern Urals.

On the basis of summarizing the results of many years of experience about environmental study of varieties and breeding varieties of spring wheat, we revealed the peculiarities of influence of plants’ assimilation apparatus parameters on the productivity level of early ripening, middle- and late ripening varieties in the forest-steppe zone of Orenburg Urals. These varieties should be used to create hybrid forms of spring wheat with optimal parameters of photosynthetic surface. This will better in solution the selection issues on efficiency in the forest of the Southern Urals. As a result, during the study of the influence of the size of the surface to the grain photosynthetic productivity level of wheat varieties, we found that in this case with an increase in the parameters of the assimilation apparatus, there is an increase of yields up to a certain limit, then a further increase in the size of the photosynthetic surface leads to lower yields. This pattern is clearly related to the fact that the overgrowing foliage due to worsening conditions for leaf photosynthetic activity, the rate of photosynthesis decreases. The following studied varieties of spring wheat have optimal parameters of the photosynthetic index: Volgouralskaya, Varyag, Kinelskaya 59, Logachevka, Lyuba, Prokhorovka, Solveig, Tulaykovskaya 1, Tulaykovskaya stepnaya and Enita. These varieties should be used to create hybrid forms of spring wheat with optimal parameters of the assimilation apparatus.
