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 aim of the study is to search for new sources of resistance to stinking smut among the ITMI population lines. The article presents analysis of data on the study of reaction of spring soft wheat, which is resistant to stinking smut, to the introduction of pathogen. The experimental part of the work was carried out in 2016-2018 on an infectious background of a phyto-stage in the conditions of the forest-steppe of the Middle Volga region (Samara ARI-branch of SamRC RAS, Bezenchuk country). 77 lines of ITMI mapping population were used as objects, as well as a population of Tilletia caries pathogen collected from zoned and susceptible varieties. In the experiment, healthy seeds (control) and seeds infected with pathogen were sown. For inoculation of wheat seeds with this pathogen, the A. I. Borggardt-Anpilogov method was used. Cleaning was carried out manually, by cutting plants from the plot in the phase of full ripeness. Accounting for damage to samples of stinking smut was carried out in the phase of milk-wax stage of the grain, carefully viewing and counting all the spikes on the plot. A five-grade scale created by V. I. Krivchenko was used for classing the samples resistance to stinking smut. Weather conditions in the years of research were different, but developed mainly favorable for creating an infectious background, as well as for the growth of spring wheat plants. 4 lines had immunity (ITMI-40, 75, 90, 91). Practical stability was observed on 5 lines (damage from 4.3 to 10.0%). 8 lines were poorly susceptible (the maximum lesion was 21.0%). With an average susceptibility, 21 lines were isolated, the remaining lines were mostly affected by more than 50%. Selected samples can serve as a valuable source material for use in immunological breeding programs.

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).
