“…Изучение комбинационной способности позволяет также иметь представление о донорских способностях сортов, роли и характере взаимодействия генов в наследовании признаков и свойств организма [10,11]. В исследованиях многих авторов отмечалось преимущество этого метода при оценке исходного селекционного материала на элементы продуктивности [12,13,14], длину стебля [15], продуктивную кустистость [16] и устойчивость к полеганию [17]. Комбинационная способность бывает общей (ОКС) и специфической (СКС).…”

In increasing the efficiency of breeding work on the creation of spring soft wheat varieties information about the combinational ability of the source material is of great importance. In 2021-2022 in the conditions of the Kirov region the general and specific combinational ability of 8 varieties and 28 hybrids of the second generation of spring soft wheat was studied according to the degree of leaf septoria damage, grain size and yield. The studies were carried out under natural conditions of development on the leaves of Parastagonospora nodorum as the molecular-genetic affiliation of the causative agent of septoria blotch to this species had been established. As the result of the conducted studies, for further breeding work there were selected 14 resistant F2 hybrids characterized by average values of the resistance index and a slow growth of infection. According to the complex of selective-immunological traits, the hybrid Rosinka 2 × Tertsiya was isolated, combining resistance to septoria with a high mass of 1000 seeds (41.6 g) and yield (410.0 g/m2). The tolerant hybrid of the Stepnaya 50 × Daria was particularly noted, which with a high degree of damage (34.2 %) formed a large grain (42.6 g) and the maximum yield for the experiment (411.1 g/m2). The conducted dispersion analysis of the data obtained has shown that the spring wheat variety Tertsiya (Russia) has a significantly high overall combinational ability (ОСА) by all the studied traits and can be their source in breeding programs. Moreover, the Epos variety (Germany) is the most effective as a source of resistance to septoria; Egisar 29, Niva 2, Stepnaya 50 and Rosinka 2 (Russia) are sources of grain size; Daria (Belarus) is a source of high yield. As the result of the analysis of the dominance index in most of the studied hybrids, the additive effect of genes on the manifestation of resistance to leaf septoria and seeds size was found. The effect of heterosis by disease resistance was observed in 21.4 %, by weight of 1000 seeds – in 42.9 % and by productivity – in 50.0 % of the studied hybrid combinations.

Abstract. The article presents the results of experimental studies on the study of seeding rates – 3, 4, 5 million germinating seeds per 1 ha, and sowing dates, in the rainfed conditions of the steppe zone of the Republic of North Ossetia Alania, on two new high-yielding varieties – Gomer and Bagrat, bred by the National Central Plant named after. P. P. Lukyanenko. The purpose of the research is to study the optimal sowing dates and sowing rates of new high-yielding winter wheat varieties in the conditions of the steppe zone of North Ossetia-Alania. Scientific novelty. For the first time in specific soil and climatic conditions of the steppe zone, the reaction of new zoned varieties to different sowing dates and seeding rates was studied. Methodology. The studies were carried out in 2019–2021, on the experimental fields of the Vladikavkaz Scientific Center, located in the steppe zone of the Mozdok region. Sowing was carried out on September 10, 20, 30. We studied seeding rates of 3, 4, and 5 million germinating seeds. Before sowing, the seeds were treated with “Tabu Neo” insecticide (to protect seeds from pests) and “Maksim Forte” fungicide (to protect seeds from pathogens). Results. It has been established that the sowing of winter wheat in the third sowing period (September 30) with a seeding rate of 5 million. of germinating seeds per 1 ha showed the best results in terms of yield, where the yield of the Gomer variety was – 4.74 t/ha, when the same variety, when sown in the 1st term (September 10), the yield was 4.45 t/ha. The same trend was revealed for the variety Bagrat, where the yield was the highest – 4.65 t/ha, with a seeding rate of 5 million seedlings. Seeds per 1 ha in the third sowing period. The studied varieties formed a heavier grain in the third sowing period (September 30). In the winter wheat variety Homer, the weight of 1000 seeds was 45.4 g. in the variety Bagrat – 43.9 g.

Relevance. On winter wheat crops, the use of mineral fertilizers and herbicides is an urgent task of agricultural production. In 2019–2021, experiments were laid in the rain–fed conditions of the steppe zone of the Mozdoksky district of the Republic of North Ossetia — Alania. The purpose of the research is to study the effectiveness of the use of mineral fertilizers and herbicides on winter wheat crops.Methods. Field experiments were laid in the steppe zone in the NGO «Oktyabrsky», in the fields of the SCNIIGPSH VNC RAS. In 2019–2021, where the climate is continental, summers are hot, dry, and winters are snowless, with frequent thaws. There is 455 mm of precipitation per year. Chestnut-carbonate soils predominate in the steppe zone of Mozdoksky district. The humus content is 2–4%. The object of research is high–yielding varieties of winter wheat Alekseich, Yumpa.Results. The use of the herbicide Gran Star (25 g/ha) ensured the death of weeds by 72.5–82.7%, when applying the herbicide Dialen Super (0.7 l/ha), the death of weeds was 60%, when applying mineral fertilizers N90P90K90 — 62.7%. The studied herbicides contributed to a decrease in the dry mass of weed vegetation (by 55.5–86.6%), an increase in the yield of the winter wheat variety Alekseich (by 4.4 t/ha), an increase of 2.4 t/ha when applying the herbicide Gran Star (25 g/ha) against the background with the introduction of mineral N60P60K60, with an increase of N90P90K90, the increase was 2.9 t/ha with a yield of 4.8 t/ha.
