During the research, there were studied 186 varieties of spring soft wheat of different ecological and geographical origin to develop valuable initial material for new varieties in the conditions of Middle Volga. The studies were carried out in accordance with the methodic recommendations of VIR. According to the duration of the growing season, the samples were divided into three groups: early ripening – 29.4 %, mid-ripening – 45.0 % and mid-late-ripening – 25.6 %. The largest number of high-yielding varieties belongs to the mid-ripening group. Five groups are distinguished according to plant height: above 120 cm – tall, 120-105 cm – medium-grown, 104-85 cm – undersized, 84-60 cm – semi-dwarfs, less than 60 cm – dwarfs. A group of semi-dwarfs showed high resistance to lodging. The yield of productive genotypes in this group is 192-210 g/m2. The analysis of the elements of the yield structure showed the varieties that exceeded the standard in the number of grains in the ear (32.8 pcs.): Annet (38.2 pcs.), Baganskaya 95 (36.5 pcs.), Riks (37.7 pcs.), Lubninka (36.8 pcs.), (Russia, West Siberian Region), Biryusa (37.2 pcs.) (Russia, East Siberian Region), by grain weight per ear – Russian varieties from East Siberian, West Siberian and Lower Volga Regions (0.96-1.52 g), and varieties of foreign selection from North America (0.89-1.64 г). According to the yield the following varieties significantly exceeded the standard variety Kinelskaya Niva (310 g/m2) by 30-54 g/m2 (LSD05 = 22.5 g/m2): Russian varieties Annet, Baganskaya 95, Lavrusha, Tarskaya 10, Pamyati Maistrenko, Omskaya 39, Duet (West Siberian region), Voevoda (Lower Volga region) and Uyarochka (East Siberian region), foreign varieties Aktyube 10 (Kazakhstan) and Granit (Canada). The varieties with complex resistance to the main types of leaf diseases (leaf rust and powdery mildew) have been identified: Norwell, Granit, Dandy, CDC Merlin (Kanada), Lavrusha, Tarskaya 10 (West Siberian Region), Tybalt (Netherlands), Voevoda (Lower Volga Region), Etyud (Ukraine). The identified varieties were used as parental forms in crosses.

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.

The complex effect of pre-sowing treatment of seeds with a protectant and liquid mineral fertilizer with subsequent foliar feeding on the growth processes and the formation of elements of productivity of hemp in the conditions of the forest-steppe of the Middle Volga region was studied. Studies have established that treatment of seeds before sowing by fungicide TMTD, VSC at the dose rate of 2.5-5.0 l/t provided the safety of the plant to harvest to 88,0-89,8 %, fertilizer Isagri Force at a rate of 1.0 l/t -- of 90.2 %. The positive influence of the investigated factors on yield structure elements: the length of inflorescence increased with the use of drugs TMTD, VSC and Isagri Force to study the consumption rates of 22.9 and 37.1 %, adding foliar treatment by 20,0% compared with the control without treatments. A significant increase in the diameter of the stem was observed when processing seeds with TMTD, VSK and Izagri Force in the consumption rates of 2.5 and 1.0 l / t by 9.5 % compared to the control. The increase in the number of internodes was promoted by treatment with drugs TMTD, VSC at a rate of 5.0 l/t and Isagri Force in doses of 1.0 and 0.5 l/t in comparison with control without treatments. Pre-sowing treatment with Izagri Force fertilizer in the consumption rates of 0.5-1.0 l / t increased the yield of seeds by 4.3 – 7.5 %. A statistically significant increase in this indicator relative to the control variant was found in the variants with Izagri Phosphorus treatment for vegetation (+0.17 t/ha or 13.6 %). The most responsive hemp plants were on the interaction of the mordant, fertilizer and foliar feeding of plants during vegetation, the increase in yield was 0.38 t / ha.
