The source material is the initial link of the selection process of any crop. A careful study of it in specific environmental conditions largely determines the effectiveness of breeding activities. The paper presents the results of a study of 102 cultivars of soft winter wheat of various ecological and geographical origin in terms of the yield, winter hardiness, the plant height, the duration of the growing season, the resistance to the frit fly. The sources of individual and a complex of economically valuable indicators were identified and recommended as the source material for breeding use in the forest-steppe conditions of the Middle Volga region.

The duration of the growing season is an important, adaptively significant indicator for any crop variety. In wheat breeding, a reliable criterion for determining the maturity group of a variety is the ear formation period. The purpose of the study was to determine the ear formation period of soft winter wheat varieties of various ecological and geographical origins in the conditions of the forest steppe of the Middle Volga region, and also to determine its effect on yield. Among the studied varieties of wheat from the world collection, German varieties were characterized by late ripeness, wheat from China, Japan, Bulgaria and the North Caucasus region of Russia by early ripeness and mid-ripeness, - varieties from the Siberian region of the country by mid-ripeness. Ukrainian cultivars were represented by wheat of different maturity groups. It has been found in the studies that under varying environmental conditions in different years early ripening, mid-early, mid-ripening and mid-late wheat can be highly productive. A well selected system of ripening varieties of soft winter wheat (65–70 % mid-ripening, 25 % mid-early and early-ripening, 5–10 % mid-late) will make it possible to use favorable environmental factors with great efficiency and withstand environmental stresses.

Research has been conducted on forming the productivity elements of main ear of soft winter wheat in the conditions of the forest-steppe of the middle Volga region. It was found that the productivity of main ear is in a strong positive correlative dependence on a number of seeds per ear and on the mass of 1000 grains. The other elements of the structure were also examined in detail – the ear length, the number of spikelets per ear, intravarietal and intervarietal variability of them.

Traits For Breeding

The work was carried out in 2018-2019 in the forest-steppe zone of Samara region. The purpose of the research is to conduct study samples of collection nursery of various ecological and geographical origins and identify new sources of economically valuable traits for breeding in the forest – steppe of the Middle Volga region. The material for research was 352 collection samples of spring soft wheat, including 108 foreign varieties and hybrids and 244 domestic samples of breeding institutions of the Russian Federation. Meteorological conditions during the research years were quite severe, and vegetation took place in arid and acutely arid conditions (hydrothermal coefficient in 2018 – 0.51, in 2019 – 0.48, with a long-term value in the region of 0.73). The greatest variability over the years of research was observed in the indicators of grain yield of samples (Сv=23.9...27.5 %) and plants height (Сv=10.8...12.9 %). According to the research results, 30 new genetic sources of economically valuable traits of spring soft wheat were identified.

The work presents the results of studies for 2017-2019, aimed at developing methods for increasing the productivity of sunflower hybrids cultivated according to the Clearfield system when using the microfertilizing mixture Agromineral in the forest-steppe zone of Middle Volga region. The results of the studies showed that the safety of plants at the time of harvesting is up to 91.8%; the maximum safety is achieved when processing crops by vegetation with Agromineral microfertilizing mixture at a dose of 3 l/ha. The leaf area increased until the budding phase, reaching a maximum of 99.2 thousand m2/ha, on a mid-season hybrid when processing crops with a dose of 3 l/ha, and then, due to drying of the lower leaves, it begins to decrease to the phase of the onset of flowering to 37.8 ... 57.9 thousand m2/ha. The maximum value of the photosynthetic potential is formed by crops of the mid-season hybrid 8N477KLDM - 4.781 million m2/ha days. The use of fertilizers and micronutrient mixtures increases its value and, as a result, increases productivity by 9.09 ... 9.36 kg/ha with an absolute indicator of 27.2 ... 33.2 kg/ha.

Tillage Treatment

The aim of the study is to increase the yield of winter wheat with the use of innovative organic fertilizers during overall tillage in conditions of the forest-steppe zone of the Middle Volga region. The research was conducted in the period involving 2017-2020. The Svetoch variety winter wheat plants, were subjected to the research. In the field experiment, organic fertilizers were applied at different tillage treatment stages. The fertilizers use during early spring sowing or winter crops aftergrowing contributed to an increase of moisture content in the meter-depth soil layer by 0.8-1.3%. Winter wheat harvesting was not affected by the soil moisture significantly depending either on fertilizers used or main tillage treatment. The organic fertilizers use led to a slight decrease in soil compaction during the sowing of early spring crops or winter wheat spring aftergrowing compared to the option without fertilizers. The in-troduction of fresh manure led to a certain increase in the contamination of crops, after the introduction of other or-ganic fertilizers studied, the number of residues and their weight was less, and no significant differences were ob-served between the variants. Factor A showed (organic fertilizers applied) during periods of 2017-2020 the yield of winter wheat was – 2.95 t/ha; fertilizers were not applied, when 30 t/ha of manure applied – 3.32 t/ha; dry organic fertilizer use – 3.35 t/ha; and liquid one – 3.36 t/ha; biohumus – 3.32 t/ha. An increase of winter wheat yield from the action of organic fertilizers was 0.37-0.41 t/ha (or 12.5-13.9%). According to factor B (main tillage), the crop yield amounted to: when plowing by 20-22 cm – 3.33 t/ha; surface tillage by 10-12 cm – 3.25 t/ha; without autumn cultural practice – 3.19 t/ha. The use of resource-saving tillage reduced the winter wheat yield by 0.08-0.14 t/ha (or by 2.5-4.4 %), that is, without a significant difference between the options.

The results of the study of 250 collection samples of spring soft wheat of various ecological and geographical groups are presented in order to identify the source material that combines optimal plant height and high productivity for the conditions of the forest-steppe zone of the Middle Volga region. The work was carried out in 2017–2020 in the Samara region. The study and evaluation of samples was carried out according to the Methodology of the state variety testing and the methodological recommendations of the VIR. The average height of plants in the samples over the years of research varied within 68.5-109.2 cm, the coefficient of variation of the trait was 11.86-13.72 %. The presence of a positive average and weak correlation between the yield and plant height, regardless of the moisture conditions of the year (r = 0.15-0.47), was revealed. A strong positive relationship was observed between the height of the samples and the following weather factors: precipitation in June (r = 0.94), precipitation during the growing season (r = 0.87), hydrothermal coefficient of June (r = 0.93), hydrothermal coefficient for the growing season (r = 0.83). The highest grain yield was formed by samples from the group of undersized and medium-grown, on average 416 and 428 g/m2, respectively. A number of highly productive varieties were identified: 3 medium-grown samples (105 cm) with a yield of 419.7-435.7 g/m2 and 21 undersized samples (85-102 cm) with an average grain yield of 485.0-585.7 g/m2. Dwarf specimens sample a stable manifestation of short-stemmed growth over the years and high resistance to lodging were noted. According to the research results, it was found that the optimal height of plants for the forest-steppe zone of the Middle Volga region is in the range of 85-105 cm. The selected undersized and medium-grown samples with high grain yield and dwarf samples with high resistance to lodging are recommended for use in breeding programs of the region and places with similar conditions.
